    GOLDEN, Justice (Ret.).
    [¶1] Brenda Miller (Plaintiff), acting as personal representative for Decedent Connie
    Rae Scribner, filed a wrongful death action alleging medical malpractice against Sean
    Beyer, M.D. and Emergency Medical Physicians, P.C. (collectively Defendants). The
    first trial ended in a mistrial and entry of an order requiring Defendants to pay attorney
    fees and costs. The second trial ended in a jury verdict in favor of Defendants.
    Following the verdict in the second trial, Plaintiff moved for a new trial on grounds that
    the district court improperly admitted undesignated expert testimony given by Defendant
    Dr. Beyer and Defendants' retained expert. The district court denied the motion, and
    Plaintiff appeals that denial. Defendants cross-appealed, challenging the district court's
    order declaring a mistrial in the first trial. We affirm both district court orders.
    ISSUES
    [¶2]   Plaintiff frames the issues for our review as follows (footnotes omitted):
    Whether the district court erred when it refused to grant the
    Plaintiff/Appellant's motion for a new trial based on three
    independently sufficient reasons?
    A.      The district court improperly admitted opinion
    testimony from Defendant's expert Dr. Kurt Bernhisel which,
    in the interest of justice, requires a new trial;
    B.     The district court improperly admitted testimony
    regarding CURB-65 which, in the interest of justice, requires
    a new trial; and,
    C.     The district court improperly allowed Dr. Beyer to
    offer speculative, non-designated expert testimony
    concerning the BUN tests on the 21st and their relation to
    sepsis which, in the interest of justice, requires a new trial.
    [¶3] In their cross-appeal, Defendants state the issue on appeal as follows (footnote
    omitted):
    Whether the district court erred when it granted a mistrial,
    and subsequently awarded fees and costs, based upon a single
    unanswered question from defense counsel that, while
    arguably lacking in form or timing, touched upon relevant
    and admissible evidence that should have been presented to
    the jury.
    1
    [¶4] In responding to Defendants' cross-appeal, Plaintiff presents the following
    additional issue concerning the timeliness of Defendants' cross-appeal:
    A.     The Cross-Appellants failed to timely file their notice
    of appeal as to the November 6, 2012 Order Allowing Costs
    and Fees for the mistrial, which was an appealable order
    because it was a [sic] "[a]n order affecting a substantial right
    in an action, when such order, in effect, determine[d] the
    action." Wyo. R. App. P. 105(a).
    FACTS
    [¶5] On October 20, 2005, Connie Rae Scribner sought treatment at the Wyoming
    Medical Center emergency room. Ms. Scribner complained of a severe cough, upper
    respiratory infection, and difficulty breathing. She was evaluated by Defendant Dr. Sean
    Beyer, and he diagnosed her as suffering from bilateral pneumonia. While in the
    emergency room, Ms. Scribner was administered intravenous antibiotics and saline,
    inhalation treatments, cough medication, and Tylenol. After Ms. Scribner spent
    approximately three and one-half hours in the emergency room, Dr. Beyer noted her
    condition had improved and discharged her with care instructions and with prescriptions
    for an antibiotic, a cough syrup with codeine, and an inhaler.
    [¶6] The following afternoon, on October 21, 2005, while at home with her twenty-
    year-old son and her boyfriend, Ms. Scribner stopped breathing. Ms. Scribner's son
    performed CPR and an ambulance was called, but Ms. Scribner died at the hospital that
    afternoon. The medical examiner found that Ms. Scribner died of "panlobar organizing
    and acute pneumonia."
    [¶7] On January 15, 2008, Plaintiff filed a wrongful death complaint against
    Defendants.1 In general terms, Plaintiff alleged that Defendants' care of Ms. Scribner fell
    below the standard of care because they failed to diagnose the seriousness of Ms.
    Scribner's condition and failed to admit her to the hospital for observation and treatment.
    [¶8] A first trial began on August 27, 2012. On the fourth day of the first trial, during
    cross-examination of Decedent's son, defense counsel asked a question that described
    Decedent as a drug addict. On August 31, 2012, Plaintiff moved for and was granted a
    mistrial. On November 6, 2012, the district court entered an Order Allowing Fees and
    Costs, which awarded Plaintiff approximately $60,000 for costs and fees incurred in
    connection with the first trial. The orders declaring a mistrial and awarding fees and
    1
    The complaint also named Wyoming Medical Center as a defendant, but by the time the matter reached
    trial, the only remaining defendants were Dr. Beyer and Emergency Medical Physicians.
    2
    costs are the subject of Defendants' cross-appeal. Additional facts related to the mistrial
    will be set forth in the discussion of that issue.
    [¶9] A second trial began on March 18, 2013. On April 1, 2013, the case was
    submitted to the jury, and on that same date the jury returned a verdict finding no
    negligence in the care and treatment of Ms. Scribner. On April 18, 2013, the district
    court entered judgment on the verdict. On May 2, 2013, Plaintiff filed a motion for new
    trial pursuant to Rule 59 of the Wyoming Rules of Civil Procedure. Plaintiff moved for a
    new trial based on the district court's rulings that allowed testimony, over Plaintiff's
    objection, by Defendant Dr. Beyer and one of Defendants' expert witnesses concerning
    theories that Plaintiff contended were not disclosed during discovery. Plaintiff's motion
    asserted:
    On April 1, 2013, after only a few hours of
    deliberations, the second jury empaneled in the above
    captioned case returned a verdict finding that Dr. Beyer was
    not negligent in his care and treatment of the decedent Connie
    Scribner. The verdict followed nearly seven years of
    litigation and two weeks of trial during which defendant and
    his expert for the first time introduced new theories relating to
    liability and new, undesignated, untested and unreliable
    surprise opinion testimony. The theories offered by the
    defendant and his "expert" were based upon an incomplete
    and inadequate understanding of the very theories they
    advanced. The surprise opinion testimony was amorphous
    and changed repeatedly throughout the expert's sworn
    testimony. The evidence confused and mislead the jury,
    violated the principles behind expert disclosures, and failed to
    meet the requirements of relevance and reliability that govern
    expert testimony, ultimately denying the plaintiff the
    opportunity for a fair trial.
    [¶10] On June 25, 2013, the district court denied Plaintiff's motion for a new trial. The
    court's denial of Plaintiff's new trial motion is the basis for Plaintiff's appeal. Additional
    facts relevant to this issue will be set forth in our discussion of the issue.
    [¶11] On July 24, 2013, Plaintiff filed her notice of appeal, and on August 6, 2013,
    Defendants filed notice of their cross-appeal.
    STANDARD OF REVIEW

    mistrial was timely filed involves the jurisdiction of this Court and is subject to de novo

    the admissibility of evidence, including whether to exclude expert testimony, for an abuse
    of discretion. Black Diamond Energy, Inc. v. Encana Oil & Gas (USA), Inc., 
    2014 WY 64

    within the sound discretion of the trial court and will not be disturbed by this Court
    absent a clear abuse of discretion."); Wilson v. Tyrrell,

    246 P.3d 265
    ,
    279 (Wyo. 2011) ("The question of the admissibility of evidence is primarily a question
    for the trial court.").
    [¶14] The following will be considered in determining whether a district court has
    abused its discretion:
    "'Judicial discretion is a composite of many things, among
    which are conclusions drawn from objective criteria; it means
    a sound judgment exercised with regard to what is right under
    the circumstances and without doing so arbitrarily or
    capriciously.'" Vaughn v. State, 
    962 P.2d 149
    , 151 (Wyo.
    1998) (quoting Martin v. State, 
    720 P.2d 894
    , 897 (Wyo.
    1986)); see also Stroup v. Oedekoven, 
    995 P.2d 125
    , 128
    (Wyo. 1999).
    In determining whether there has been an abuse of
    discretion, we focus on the "reasonableness of the
    choice made by the trial court." Vaughn, 
    962 P.2d 149
    ,
    151 (Wyo.1998). If the trial court could reasonably
    conclude as it did and the ruling is one based on sound
    judgment with regard to what is right under the
    circumstances, it will not be disturbed absent a
    showing that some facet of the ruling is arbitrary or
    capricious.

    DISCUSSION
    [¶15] Addressing the issues in chronological order, rather than in the order in which they
    were presented on appeal, we first address Defendants' appeal from the order granting a
    mistrial in the first trial. We will then turn to the issues related to the admission of expert
    testimony in the second trial and the denial of Plaintiff's motion for a new trial following
    the jury's unfavorable verdict in that second trial.
    A.     Order Granting Mistrial
    [¶16] The district court declared a mistrial of the first trial because, on cross-
    examination of Decedent's son, defense counsel asked a question that described Decedent
    as a drug addict. The court found the question improper on grounds that the question
    assumed facts not in evidence, called for speculation, was based on hearsay, was not
    relevant, and was unfairly prejudicial to Plaintiff. In considering Defendants' appeal of
    the mistrial order, we will first address Plaintiff's argument that Defendants' appeal was
    not timely, and then we will consider Defendants' abuse of discretion argument.
    1.     Timeliness of Appeal
    [¶17] On August 31, 2012, Plaintiff moved for a mistrial, and the district court granted
    that motion. In so ruling, the court directed Plaintiff's counsel to submit an application
    for costs and fees and indicated it would rule on that application after Defendants'
    counsel had an opportunity to respond. The court also set a scheduling conference for the
    purpose of choosing a date for the second trial.
    [¶18] On September 5, 2012, the district court issued a Scheduling Order that set a new
    trial date of March 18, 2013. On September 17, 2012, Plaintiff filed her motion for
    attorney fees and costs related to the mistrial, and on October 2, 2012, Defendants
    responded to that motion. On November 6, 2012, the court entered an Order Allowing
    Costs and Fees.
    [¶19] Plaintiff does not contend that the district court's August 31, 2012 order granting
    Plaintiff's motion for a mistrial was an appealable order. Instead, Plaintiff contends that
    the court's Order Allowing Costs and Fees was the appealable order and that because
    Defendants did not file their cross-appeal until August 6, 2013, their appeal of the
    mistrial order and Order Allowing Costs and Fees was untimely. We disagree.
    [¶20] In arguing that Defendants' appeal was untimely, Plaintiff relies solely on Rule
    1.05(a) of the Wyoming Rules of Appellate Procedure. Rule 1.05(a) defines an
    appealable order as "[a]n order affecting a substantial right in an action, when such order,
    in effect, determines the action and prevents a judgment." W.R.A.P. 1.05(a). This Court
    5
    has held that "an appealable order under Rule 1.05(a) has 'three necessary characteristics.
    . . . It must affect a substantial right, determine the merits of the controversy, and resolve
    all outstanding issues.'" In re E.R.C.K., 
    2013 WY 160
    , ¶ 28, 
    314 P.3d 1170
    , 1176 (Wyo.
    2013) (quoting In re KRA, 
    2004 WY 18
    , ¶ 10, 
    85 P.3d 432
    , 436 (Wyo. 2004)). Said
    another way, to be appealable, an order must leave nothing for future consideration. In re
    KRA, ¶ 10, 85 P.3d at 436 (citing Public Serv. Comm'n v. Lower Valley Power & Light,
    Inc., 
    608 P.2d 660
    , 661 (Wyo. 1980)). The purpose of these Rule 1.05 requirements is
    "to avoid fragmentary appeals and decisions made in a piecemeal fashion." Estate of
    McLean ex rel. Hall v. Benson, 
    2003 WY 78
    , ¶ 8, 
    71 P.3d 750
    , 753 (Wyo. 2003).
    [¶21] Applying these principles, the district court's orders granting a mistrial and
    awarding costs and fees were not appealable orders. While the question of the mistrial
    may have been settled once the court issued its order awarding costs and fees, that issue
    was only one discrete part of the controversy. The parties' controversy would not be fully
    determined on the merits until after the second trial. The orders declaring a mistrial and
    awarding costs and fees thus did not determine the action or prevent a judgment as
    required by Rule 1.05(a), and a ruling that the mistrial orders were immediately
    appealable would necessarily result in the type of fragmentary appeals and piecemeal
    decisions that Rule 1.05 was intended to avoid. See Davis v. Davis, 
    985 P.2d 643
    , 646-47
    (Ariz. Ct. App. 1999) (holding that an order granting a mistrial prior to judgment being
    entered is not an appealable order because such an order neither determines the action nor
    prevents judgment from which an appeal might be taken); Howard v. Kuehnert, 
    641 N.E.2d 804
    , 805-06 (Ohio Ct. App. 1994) (interpreting provisions similar to W.R.A.P.
    1.05 and holding that orders relating to declaration of mistrial not appealable because a
    new trial necessarily follows).
    [¶22] This case has taken an appellate path similar to that followed in Terry v. Sweeney,
    a personal injury lawsuit involving a motor vehicle accident. Terry, 10 P.3d at 555. A
    mistrial was declared in Terry when a witness for the plaintiff, in violation of a pretrial
    order, referenced the defendant's insurance coverage. Id. at 556. The trial court entered
    an order awarding costs related to the mistrial, and the matter remained pending for two
    years because the court would not set a new trial until the plaintiff paid the costs. Id. The
    plaintiff continued in her failure to pay the award of costs, and, nearly three years after
    entry of the original order awarding costs, the trial court entered an order of dismissal
    with prejudice. Id. at 557. The plaintiff then appealed the dismissal order and the orders
    declaring a mistrial and awarding costs. Id. This Court did not directly address the
    timeliness of the plaintiff's appeal from the orders declaring a mistrial and awarding
    costs, but given our willingness to dismiss an appeal on our own motion when we find
    that an order is not appealable, our acceptance of the appeal and ruling on the issues
    presented signaled that the appeal had been properly taken. See Bd. of Trustees of Mem'l
    Hosp. of Sheridan Cnty. v. Martin, 
    2003 WY 1
    , ¶¶ 9-16, 
    60 P.3d 1273
    , 1275-77 (Wyo.
    2003) (dismissing appeal on ground that order was not appealable though issue was not
    raised by parties).
    6
    [¶23] Our ruling in Terry implicitly recognized that an order declaring a mistrial is not
    an appealable order itself and that the proper procedure for appealing such an order is to
    take an appeal after the parties' controversy is fully determined on the merits. See also
    Dollarhide, ¶ 16 n.5, 239 P.3d at 1173 n.5 (reviewing the trial court's exercise of
    discretion in granting a mistrial while at the same time observing the arguable mootness
    of the issue given that by the time a mistrial ruling makes its way to the Court on appeal
    the jury has been released and another trial has taken place).
    [¶24] The orders declaring a mistrial and awarding costs and fees did not determine the
    action or prevent a judgment, and neither order was therefore an appealable order as
    defined by W.R.A.P. 1.05(a). We thus conclude that Defendants' appeal of the mistrial
    order was timely and turn then to Defendants' argument that the district court abused its
    discretion in declaring a mistrial.
    2.     District Court's Exercise of Discretion in Declaring Mistrial
    [¶25] As noted above, the offending question that led the district court to declare a
    mistrial was one that described Decedent as a drug addict. Evidence relating to
    Decedent's alleged use of Vicodin and marijuana, her alleged alcohol use, and her alleged
    drug-seeking behaviors was the subject of motions in limine and multiple arguments to
    the district court, both pretrial and during trial. At a pretrial motions hearing, Defendants
    argued that the evidence was relevant to Decedent's cause of death and was therefore
    admissible. Essentially, Defendants contended that Decedent misused her prescription
    medications and consumed alcohol and marijuana, and that these actions combined with
    Decedent's pneumonia to cause her respiratory failure. Plaintiff argued for exclusion of
    evidence related to Decedent's history of drug and alcohol abuse on grounds that the
    prejudicial nature of the evidence outweighed its probative value because there was no
    evidence that showed a recent use of Vicodin or a link between Decedent's marijuana use
    and her respiratory failure. At a pretrial motions hearing, the district court ruled that
    evidence related to Decedent's past abuse of Vicodin was not admissible because the
    allegations were too remote in time. With respect to Decedent's use of marijuana, the
    court ruled:
    THE COURT: My inclination is to grant the motion with
    regard to the THC. I'm getting different versions of what the
    experts are going to say, so I am – I'm reserving to the
    defendant if they can somehow specifically tie the THC to the
    cause of death; but, you know, if the argument is, Well, she
    was smoking marijuana and under the influence and made a
    bad decision, I don't see any experts willing to say that – I
    may have missed that – but, you know, you have to somehow
    say she had X number of nanograms in her system and then
    7
    this is how it affects her judgment. I may have missed it, but
    I don't see that in any of the designations.
    ****
    THE COURT: It does seem to me to be more prejudicial than
    probative of anything; but I – as the testimony develops, I
    will reconsider that ruling at the request of the defendants.
    [¶26] On the first morning of the first trial, defense counsel requested clarification on the
    district court's rulings concerning Decedent's drug use, and the following exchange took
    place:
    [Defense Counsel]: * * * Due to the delicate nature of a few
    of the rulings that you've made in the past, the Zithromax and
    Vicodin and marijuana and so on, we just want to make sure
    that we all understand what to say and what not to say during
    voir dire and openings.
    So the first question I have, I know there was a motion
    that you heard about a particular ER record with Connie
    Scribner, where she admitted she had been seeking Vicodin;
    and you said there's no reason to reference that record. And
    that's fine. What we would like to do, however, Your Honor,
    is establish that she was a drug seeker, because it goes to –
    the plaintiffs have made a big deal about who it was that
    could have possibly consumed the medications at her home.
    The fact that she's a drug seeker in the past goes to the fact
    that she sought the high from time to time for whatever
    medications she could get, and it establishes and provides
    some background information about who in fact was the most
    likely person to have taken the extra gabapentin and the
    codeine cough syrup. So your ruling was specifically tailored
    to that specific medical record; but we didn't want to violate
    anything by mentioning other Vicodin or other records that
    reference that or her history of drug-seeking behavior.
    [Plaintiff's Counsel]: * * * Well, I know that your ruling was
    specific to that record; but it was based upon the idea that the
    nature of the drugs she had admitted to seeking a year prior,
    over a year prior, was Vicodin; that there was no Vicodin in
    her system. It was tested for. There was no evidence that she
    had engaged in any drug-seeking behavior for at least a year
    8
    prior to this event. And that it is therefore a prior bad act
    which should be excluded. And so the – the discussion was a
    lot broader than, Oh, can we – do we erase the reference in
    this record. I think that was the context in which it came up,
    but it was because of the remoteness in time and the risk of
    unfair prejudice relating to it and also that – that there was no
    evidence to – to support admission of such evidence under
    habit or anything else because of the lack of time and the
    dissimilarity between that particular drug that is historically
    an issue and the drugs involved at the time of this event.
    [Defense Counsel]: Even though the drug at issue in this case
    wasn't whether Vicodin killed her, the cause of her death is
    definitely an issue. And one of the – our entire theory of the
    case is that she overmedicated herself. And so it goes to that
    point, because they have contested that she consumed the
    cough syrup and they have contested that she consumed the
    gabapentin without any proof whatsoever that anybody else
    could have taken it. And so it's important for that, Your
    Honor, on this particular issue.
    THE COURT: You may respond to those things but only
    those things. As to other drug-seeking proclivities, I will rule
    on those questions as they come up. But do not address it in
    your opening.
    [¶27] On the second day of trial, the issue of Decedent's drug use again raised its head
    when Plaintiff's expert referred to Decedent's past "prescription drug issues" during cross-
    examination by defense counsel. The following exchange then occurred:
    [Plaintiff's Counsel]:     Through no doing of [Defense
    Counsel], there was testimony from the doctor that the
    medical records in the past indicated some prescription drug
    issues. Right now, I would like to leave that alone. I would
    like the opportunity – because we have a motion in limine to
    preclude that evidence. I think that the doctor is tired
    because, of course, I informed him of that. I don't want it to
    go further. I would like the opportunity to discuss with the
    witness that it is not something he should say. I don't think it
    was error in any way for [Defense Counsel]. I'm not
    objecting to that. I don't have a problem with that. I would
    like the opportunity now to make it not worse, and I do not
    think that he opened the door to it because he just said issues
    9
    and not – didn't define it any more. So I would like to stop it
    in its tracks.
    [Defense Counsel]: * * * I understand that you have ruled
    that the 2004 incident with regard to the Vicodin is not
    admissible; and I wasn't really focused on him saying what he
    said. I don't intend to go further with it right now; but I want
    you to know that it is my position that her drug-seeking
    mentality is at issue and it's germane to Dr. Kulig's opinions
    in this case about what happened to the drugs and what
    happened to Connie.
    THE COURT: All right. I'm not going to make a ruling on
    that at this point.
    [¶28] On the third day of the first trial, another exchange took place between the court
    and counsel concerning evidence related to Decedent's alleged drug use:
    THE COURT: Okay. I want to at least have you prepared to
    discuss something if you're not now, and I suspect you're not.
    An issue has come up occasionally – and my guess is it's
    going to – there's going to be [an] increasing chance for it
    come up the further we go into this case. And I can't
    remember the phrase that [Defense Counsel] uses, but it has
    to do with allegations of drug abuse by Ms. Scribner. And
    you referred to that as high seeking or –
    [Defense Counsel]: Drug seeking.
    THE COURT: Drug seeking. So I'm not sure what it is that
    you're trying to establish. Are you trying to establish habit or
    are you trying to establish character or character through
    habit? I want some – I'm trying to prepare for this, so I'm
    trying to delineate the issue.
    ****
    [Defense Counsel]: It's character. And it comes under
    404(b), where it says it's admissible for other purposes, such
    as proof of motive, opportunity, intent, those sorts of items.
    And just so they can respond to both of the things, I just want
    to make sure we don't run into a problem with Adam
    Scribner.
    10
    THE COURT: I just wanted to know what the issue was so I
    can be prepared. I don't know if you said you want to
    respond now or not.
    [Defense Counsel]: Can I say one more thing? Just because I
    don't want anybody to be unfairly surprised, and I want to be
    fair, too.
    But with Adam Scribner, there's evidence in the
    records – he's claiming damages in this case as a family
    member based upon his relationship with his mother and what
    he's lost as a result of her death. There is evidence in the
    records that she told medical providers that her kids believed
    she was a drug addict and – along with other opinions that her
    kids had of her. But I'm going to ask that question of him,
    you know, Did you believe your mom was a drug addict. I
    don't know what he'll say. But it's in the records that she
    reported that to medical providers. And so it's not to show
    whether she was a drug addict on the day that she actually
    died, but it's relevant to the relationship that they had with
    one another and his claim for damages and the daughter's
    claim for damages, as well.
    ****
    THE COURT: If this is not going to come up in this next
    witness, we can postpone this discussion and bring the jury
    back in and go forward. I didn't mean to get so distracted. I
    was just trying to delineate the issue. I didn't really mean to
    get into a full-blown argument on it.
    [Defense Counsel]: I believe that Dr. Beyer is the next
    witness, they will tell you. But if he's the next witness, this
    probably is not coming up in his testimony.
    THE COURT: All right. Let's proceed, then, with the jury;
    and we'll discuss this. But the parties are going to have to
    alert me when they anticipate it.
    [¶29] On the fourth day of the first trial, defense counsel's cross-examination of
    Decedent's son, Adam Scribner, led to the following exchange and motion for a mistrial:
    11
    Q. Did you ever think of your mom as a drug addict?
    A. No, absolutely not.
    Q. Do you have any idea why she would report that to any of
    her health care providers, that her children thought she was a
    drug addict?
    [Defense Counsel]: Your honor, may we approach?
    THE COURT: Yes.
    [Bench Conference]
    THE COURT: So we're here.
    [Defense Counsel]: And I'm not going any further.
    [Plaintiff's Counsel]: It's too late. Thank you very much.
    I request a mistrial. This is subject to a motion in
    limine to preclude prior drug use. We talked about it three
    times, not less than that. And now you're coming up and
    you're asking him in front of the jury, Do you know why your
    mom would tell health care providers she's a drug addict. Not
    only is this something that's been the subject of motions in
    limine but it's also hearsay.
    [¶30] The district court then excused the witness, recessed for the day, and instructed
    counsel to reconvene the following morning for further discussion of Plaintiff's motion
    for a mistrial. The next morning, August 31, 2012, the hearing on Plaintiff's mistrial
    motion was held. At the outset of the hearing, the court described its concerns with the
    question asked by defense counsel:
    There are many, many problems with this question.
    First, it assumes a fact not in evidence. Not only does it
    assume a fact not in evidence, it assumes a fact unlikely to be
    in evidence.
    Secondly, when a question starts "Do you have any
    idea," that certainly is a red flag that it's going to call for
    speculation. And in this case, it does. So it requires the
    witness to speculate.
    12
    Third, it is hearsay based on hearsay; arguably, double
    hearsay; and depending on the context of the question, triple
    hearsay.
    Fourth, it has questionable, at best, relevance. If the
    question is offered to show Adam's impression of his mother,
    putting aside all of the other problems that I mentioned, then
    it proves nothing, because you can't determine from the
    context of the question whether assuming he said that – and
    I'm only assuming that for purposes of this limited discussion
    – he was asking for help, he was being critical of her, or he
    was not doing either. And, again, that's assuming he asked
    for it, and I'm not making that assumption. If it is offered to
    show Ms. Scribner's character, then it doesn't establish
    anything.
    Finally, it is extremely prejudicial for two reasons.
    First, it is the use of the term "drug addict." It did not say use
    drugs, controlled substance, or prescription medicine. It did
    not even say abused drugs or controlled substances or
    prescription medicine. And I think the term "drug addict" for
    many of us brings up or conjures visions of people in alleys
    shooting up with needles in dirty places.
    It is also prejudicial because it can't be answered. It's
    worse than when did you stop beating your dog. If Adam
    were to say he has no idea why his mother would say that, it
    still leaves open the suggestion that he thought his mother
    was a drug addict or worse, that she was a drug addict. If he
    says he has no idea and he didn't say that, it still leaves open
    the suggestion that his mother might have said it; and he
    obviously has no ability to respond to that question.
    So the question clearly can't stand. And there wasn't
    formally an objection; but I assume for all practical purposes
    there was, and that objection is sustained.
    The question should not have been asked. I have to
    believe that very little critical thought was given to that
    question. It is difficult for me to say this, because I have
    known [Defense Counsel] for many years – I think she
    appeared in front of me when I was a county judge – but the
    13
    fact of the matter is I think that's the worst question I've ever
    heard posed to a witness in my legal career.
    You notice that in my discussion I have not considered
    the impact of the liminal motions on Vicodin or marijuana.
    There are a couple of problems with that. No orders have
    been entered that I can find. I did review my oral rulings.
    They are not specifically on point, but it's difficult for me to
    believe that anybody who was present for those hearings
    didn't understand I had any serious reservations about any
    mention of any other drugs. But that's not part of my analysis
    nor am I considering this part of my analysis, my belief that I
    thought the parties would approach first before these kinds of
    things were brought up. That may not have been clear, and so
    I'm not really considering that.
    But as I said, the question was – the objection is
    sustained. It should not have been presented. And so we're
    now going to focus on what the remedy is.
    [¶31] After additional discussion and argument concerning possible curative
    instructions, Plaintiff renewed her motion for a mistrial. The district court granted the
    motion, stating:
    I think that the remarks made by counsel were not
    made in bad faith. It was a momentary lapse in judgment and
    that's all, and everybody is susceptible to that. But they are
    such that objection and instructions to disregard them cannot
    cure the resulting prejudice. So I will grant the motion for a
    mistrial.
    [¶32] Defendants argue that the district court abused its discretion in granting a mistrial.
    In so arguing, Defendants challenge the court's conclusion that the healthcare record on
    which defense counsel based her question, and Decedent's alleged statement contained in
    that record, were inadmissible. As the linchpin of their analysis, Defendants contend that
    neither the healthcare record nor Decedent's statement contained within that record
    constituted inadmissible hearsay. They assert:
    Absolutely no analysis was made as to whether the statements
    were subject to hearsay exceptions. This is particularly
    problematic, because even a rudimentary inquiry into the
    hearsay exclusionary rule and its exceptions would have
    likely yielded a different result. Given the absence of any
    14
    meaningful discussion or reference to the actual hearsay rules,
    the court's conclusions were not reasonable or based upon
    sound judgment.
    [¶33] The Defendants follow this statement with a detailed argument as to why the
    record and Decedent's statements therein were not hearsay. The record shows, however,
    that Defendants' hearsay arguments were not presented to the district court. Not only did
    Defendants not argue to the district court that the healthcare record and Decedent's
    statement therein were not hearsay, defense counsel informed the court that she had no
    intention of seeking admission of the healthcare record. Defense counsel stated, our
    emphasis added:
    They are asking for a lot of money for damages. And
    he continually described this very good relationship he had
    with his mom. And in the record I was referencing, I didn't
    put it in evidence and I didn't plan to, because there was
    more in that record; but it was from Central Wyoming
    Counseling Center, I believe. And it referenced that – her
    horrible relationship with her kids. They think I'm a drug
    addict. I wasn't going to be cruel to Adam and point out what
    his mom thought of her kids. There's so many references in
    many of the medical records that she was less than fond of
    her children. And I wasn't going to ever go that direction.
    That would be cruel. But the fact is they were talking about
    their opinions of one another, their relationship. He had
    already talked about his conviction for a couple of drug-
    related crimes. And so it went right to that issue in my mind.
    Apparently, it was very poor judgment. And I – believe me;
    I'm very apologetic for that. I – I thought I alerted everybody
    to that. And I – maybe I'm ignorant about how harmful that
    question could have been. It was not intentional.
    [¶34] This Court has repeatedly stated that it will not consider arguments made for the
    first time on appeal. State ex rel. Dep't of Family Serv. v. Kisling, 
    2013 WY 91
    , ¶ 14, 
    305 P.3d 1157
    , 1162 (Wyo. 2013); BP America Prod. Co. v. Dep’t of Revenue, 
    2006 WY 27
    ,
    ¶ 33, 
    130 P.3d 438
    , 468 (Wyo. 2006). And we have explained why new arguments are
    particularly problematic when we are reviewing a court's decision for an abuse of
    discretion:
    It simply is not appropriate for this Court to reverse a district
    court ruling on grounds that were never presented to it.
    Whitten v. State, 
    2005 WY 55
    , ¶ 24, 
    110 P.3d 892
    , 898 (Wyo.
    2005). This is particularly true when our review is for an
    15
    abuse of discretion because to determine whether there was
    an abuse we necessarily must consider the arguments and
    evidence presented to the district court. Amoco Prod. Co. v.
    Dep’t of Revenue, 
    2004 WY 89
    , ¶ 53, 
    94 P.3d 430
    , 449 (Wyo.
    2004). Plainly stated, a party cannot fail to present an
    argument and then argue on appeal that the district court
    abused its discretion in not considering the argument the party
    did not present.
    Sundance Mtn. Resort, Inc. v. Union Tel. Co., 
    2007 WY 11
    , ¶ 17, 
    150 P.3d 191
    , 196
    (Wyo. 2007).
    [¶35] In arguing against the motion for mistrial, defense counsel did not contest the
    district court's characterization of the question as being based on inadmissible hearsay,
    assuming facts not in evidence, or calling for speculation. Instead, defense counsel
    argued that: 1) she did not believe her question violated any of the court's orders; 2) that
    the question went to the quality of Decedent's relationship with her children and was
    therefore relevant to damages; and 3) that the question was not unfairly prejudicial to
    Plaintiff. Defense counsel concluded her argument:
    The Court, of course, granting a mistrial is an extreme
    and drastic remedy that should be resorted to only in the face
    of an error so prejudicial that justice could not be served by
    proceeding with trial. So the question remains what potential
    prejudice does exist with the jury. At the time that question
    was asked, the jury already knew that Ms. Scribner had high
    levels of codeine in her system; that she had alcohol in her
    system; that she was on multiple medications for her bipolar
    disorder; that she had gone to Wyoming Medical Center
    emergency room in excess of 40 times; and that she had
    smoked pot with her son as early as two weeks before her
    death. They didn't object to any of that. And so the jury
    already had that information about her. This and what a –
    whether he knew what his mom told the medical care
    provider, to me, doesn't add anything more detrimental or
    more damaging than what the jury already knew about Ms.
    Scribner. And so I think we're lacking the prejudice
    necessary to grant a mistrial.
    I agree wholeheartedly that you should give a
    cautionary – or a curative instruction to the jury and blame it
    on me and say that I asked an inappropriate question. I'm fine
    with that. * * *
    16
    So I would just ask that an instruction be given to the
    jury that questioning by [Defense Counsel] to Adam Scribner
    regarding drug-addict questions were improper and
    inappropriate and that they should disregard them, you know,
    judge the case based on the evidence, the questions of
    attorneys are not evidence, that kind of thing.
    I'm sorry, other than that.
    [¶36] Given that defense counsel did not argue before the district court that the court
    was wrong in its conclusion that the offending question was based on inadmissible
    hearsay, assumed facts not in evidence, or called for speculation, we will not consider
    Defendants' arguments to that effect on appeal. Instead, we will confine our review to the
    question of whether the district court abused its discretion in finding that the question was
    so prejudicial as to warrant a mistrial.
    [¶37] The district court found defense counsel's question "extremely prejudicial"
    because of its use of the term "drug addict" and the negative connotations associated with
    that term and because the question could not be answered in a meaningful way by the
    witness. We have previously explained why it is difficult for this Court to second-guess
    such a determination by a trial court:
    The gravamen of the mistrial motion, as well as the
    district court’s rationale for granting the motion, was that
    Dollarhide’s counsel had irrevocably tainted the jury by
    telling it, in effect, that Judge Guthrie had found Dollarhide to
    have a valid case against the defendants. The reason that we
    must affirm the district court is that it is impossible to show
    that the mistrial decision was unreasonable or arbitrary or
    capricious under these circumstances. While it is the law that
    “[g]ranting a mistrial is an extreme and drastic remedy that
    should be resorted to only in the face of an error so
    prejudicial that justice could not be served by proceeding with
    trial[,]” it is also the law that “[t]he trial court is also in the
    best position to assess the prejudicial impact of such error.”
    Warner v. State, 
    897 P.2d 472
    , 474 (Wyo. 1995); see also
    Martin v. State, 
    2007 WY 2
    , ¶ 19, 
    149 P.3d 707
    , 712 (Wyo.
    2007). We are in no position to second-guess the trial court’s
    on-site, real-time assessment. Dollarhide argues that, “even if
    the statement was improper, it could have been cured by an
    instruction.” Obviously, we also are in no position to test the
    accuracy of that assumption.
    17
    Dollarhide, ¶ 16, 239 P.3d at 1173 (footnote omitted).
    [¶38] The question of Decedent's alleged drug abuse and whether evidence would be
    permitted regarding those and related allegations was the subject of multiple arguments
    and discussions between counsel and the district court. The record clearly illustrates that
    the court was sensitive to the potential prejudice of such evidence and intended to allow
    its use for only limited purposes when appropriate. The district court was in the best
    position to assess how evidence was being received and whether an improper question
    had so crossed a line that the unfair prejudicial taint was irrevocable. Based on the record
    before us, we cannot find that the court's assessment was unreasonable, arbitrary or
    capricious.
    B.     Order Denying Plaintiff's Motion for New Trial
    [¶39] We turn then to Plaintiff's appeal. We will begin our discussion of Plaintiff's
    appeal with an overview of the parties' competing theories concerning whether the
    standard of care required that Decedent be hospitalized. Against that backdrop, we will
    discuss the district court's admission of testimony by Defendant Dr. Beyer and
    Defendants' emergency medicine expert, Dr. Kurt Bernhisel, and Plaintiff's objections to
    that testimony and motion for new trial based on that testimony.
    1.     Overview
    [¶40] As noted earlier, in general terms, Plaintiff alleged that Defendant Dr. Beyer's care
    of Decedent fell below the standard of care because he failed to diagnose the seriousness
    of Decedent's condition and failed to admit her to the hospital for monitoring and
    treatment. More particularly, Plaintiff's theory, presented through her emergency
    medicine expert, Dr. Anthony Haftel, was that Defendant Dr. Beyer should have
    diagnosed Decedent as suffering from sepsis, which is a toxic response to an infection,
    and should have recommended hospitalization to treat the sepsis.
    [¶41] In offering this theory, Dr. Haftel testified to a definition of sepsis, which he
    described as a nationally accepted guideline. Dr. Haftel defined sepsis as an infection
    plus SIRS, which is the acronym for systemic inflammatory response syndrome. He
    explained that SIRS occurs when a patient has two or more of the following symptoms:
    1) a temperature greater or equal to 38 degrees Celsius (100.4 degrees Fahrenheit); 2) a
    pulse rate over 90 beats per minute; 3) a respiratory rate over 20 breaths per minute; and
    4) a white blood cell count greater than 12,000. Essentially, Dr. Haftel testified that a
    patient has sepsis if the patient has an infection, such as pneumonia, and two of the four
    SIRS symptoms.
    18
    [¶42] Dr. Haftel testified as to the danger of sepsis, explaining that sepsis can progress
    on a continuum: sepsis to severe sepsis to septic shock to multiple organ dysfunction and
    eventually to death. He further testified that this progression can occur in some cases
    within twenty-four hours and that a diagnosis of sepsis requires hospitalization.
    [¶43] Dr. Haftel concluded that when Decedent first presented to the emergency room
    on October 20th, she had pneumonia and met two of the four SIRS criteria: her white
    blood cell count was elevated above 12,000 and her pulse rate was greater than 90. He
    further concluded that when Decedent was discharged from the emergency room, a few
    hours later, her condition had worsened and she met all four of the SIRS criteria. On this
    basis, Dr. Haftel opined that Decedent had sepsis and that the standard of care required
    that she be admitted to the hospital for monitoring and treatment.
    [¶44] Defendants did not dispute Plaintiff's definition of sepsis. Defendant Dr. Beyer
    testified, on examination by Plaintiff's counsel:
    Q. [Dr. Haftel] talked about the four criteria for systemic
    inflammatory response syndrome. And are those accurately
    reflected there?
    A. They are.
    Q. Okay. And you know and knew in 2005 that it only takes
    two or more of those criteria to conclude that a patient has
    systemic inflammatory response syndrome?
    A. Yes.
    Q. And do you agree that pneumonia is an infection in the
    lungs?
    A. Yes.
    Q. And so if somebody has pneumonia and two or more of
    these criteria, would you agree that they have – they meet the
    definition for sepsis?
    A. Yes.
    [¶45] Defendants did not dispute the SIRS plus infection definition of sepsis. What they
    instead challenged was Plaintiff's assertion that the standard of care requires
    hospitalization of any patient who presents with symptoms meeting that definition of
    sepsis. Defendants presented testimony, through Defendant Dr. Beyer and through
    19
    Defendants' expert, Dr. Bernhisel, that the SIRS plus infection definition of sepsis is not a
    good prognostic tool for predicting whether a patient will progress through the sepsis
    spectrum from sepsis to severe sepsis to septic shock to organ failure and death.
    Essentially, Defendants' position was that the SIRS plus infection definition of sepsis is
    an overly cautious and overly sensitive guideline for determining when a patient must be
    hospitalized. In keeping with that view, Dr. Bernhisel testified on direct examination by
    defense counsel:
    Q. How many pneumonia patients have three or four of the
    SIRS criteria and an infection?
    A. A lot. I don't have – I don't know if there's a statistic that
    would tell you – tell you that. But we see a lot of
    pneumonias, and the majority of them have SIRS criteria.
    Q. Do you admit the majority of them or send the majority of
    them home?
    A. We send the majority of them home.
    [¶46] Defendants offered alternative guidelines, known by the acronyms CURB-65 and
    PORT, which Defendants contended were more accurate predictors of mortality risk
    associated with pneumonia and provided better guidance on whether a patient should be
    hospitalized. CURB-65 is a pneumonia severity index, with each letter of the acronym
    signifying a condition in the patient. Broken down, the letters stand for: C-confusion; U-
    urea, requiring an elevated blood urea nitrogen (BUN) level; R-respiration, requiring a
    respiratory rate elevated to more than 30 breaths per minute; B-blood pressure, requiring
    a systolic blood pressure below 90 or a diastolic blood pressure below 60; and 65 stands
    for an age of 65 or greater. The index specifies that a patient meeting one or two of these
    criteria may be discharged home and a patient meeting three criteria should be considered
    for hospital admission or very close monitoring.
    [¶47] PORT is an acronym that refers to the title of a study: "Pneumonia Patient
    Outcomes Research Team (PORT) validation study (1991)." The PORT guideline
    requires consideration of factors such as demographic features, physical exam features
    and initial vital signs, including age, altered mental status, pulse, blood pressure, and
    respiratory rate, and, then based on those factors, classifies the level of the patient's
    mortality risk.
    [¶48] Defendant Dr. Beyer testified that application of the CURB-65 criteria to
    Decedent's symptoms on October 20 indicated that it was acceptable to discharge her
    home. Dr. Bernhisel testified that based on application of either the CURB-65 criteria or
    20
    the PORT criteria, Decedent had a low mortality risk and it was acceptable to discharge
    her home.
    [¶49] With this background on the parties' competing theories, we will turn to Plaintiff's
    objections to certain of the testimony by Drs. Beyer and Bernhisel.
    2.    Plaintiff's Objections
    a.    Dr. Bernhisel's Testimony
    Dr. Bernhisel's Testimony Re: SIRS Plus Infection Definition of Sepsis
    [¶50] During trial, Plaintiff's counsel objected to two aspects of Dr. Bernhisel's
    testimony. His first objection was to Dr. Bernhisel's testimony that although the SIRS
    plus infection definition of sepsis is useful in a research setting, it is not useful in a
    clinical setting for predicting whether a patient will progress further on the sepsis
    continuum or for assessing whether a patient should be hospitalized. Specifically, Dr.
    Bernhisel testified concerning a follow-up study on the SIRS plus infection definition of
    sepsis, explaining:
    Then the next conclusion was that these definitions do
    not allow for precise staging or prognostication of the host
    response to infection. That's kind of gobbledygook, but let
    me try to give you what I think it says. That these definitions,
    the SIRS sepsis definition, are not such that you can say,
    Well, if you've got two of these or three of these, you're more
    severe than somebody that has just two of them, or four
    means that they are sicker than three. I think you heard
    testimony that Dr. Haftel said if they had four of them, that
    was worse than three. And there is no staging. It's not – it's
    not – it's not that type of a – of a system. So – and you can
    also not prognosticate. There are – which means predict.
    You can't predict from this how the host – it's a great word; it
    means patient. But when you're a scientist and academician,
    you're going to use a word like "host." Clinicians often use
    "patient." You can't predict how each patient is going to
    respond to these SIRS definition. It's SIRS sepsis. It's – it's –
    they can't look at that and say, Yes, because you've got this, it
    means that you're sicker than – than something else. So the –
    it's a very nonpredictive tool. Okay?
    And the other important thing says, While SIRS
    remains a useful concept, the diagnostic criteria for SIRS
    21
    published in 1992 are overly sensitive and nonspecific. It's
    just like I've been saying. You – you – how you use that
    information is – is so hard. You're – you're taking everything
    in on your – so sensitive it gets all kinds of – of patients that
    may not be clinically relevant and labeled as SIRS sepsis. So
    it's – it's a – it's a useful tool to have this concept of a
    continuum of sepsis; but it may not be as useful clinically
    when you're seeing a patient that has some of these findings
    or all of the findings. You still have to have a lot of other
    information. It's – it's – it's a piece of information, but it's not
    a predicting piece of information.
    [¶51] Dr. Bernhisel further testified that the definition of sepsis that he finds useful in
    the clinical setting is termed "clinical sepsis," which he explained is the same as "severe
    sepsis" on the SIRS plus infection sepsis continuum. Plaintiff objected to all of this
    testimony on the ground that it was not designated in Dr. Bernhisel's expert designation
    and amounted to unfair surprise.
    [¶52] On the question of whether Dr. Bernhisel's opinions were disclosed in his expert
    designation, defense counsel agreed at trial that Dr. Bernhisel's designation did not
    reference the SIRS plus infection definition of sepsis or Dr. Bernhisel's opinions
    concerning the clinical value of the definition. Defense counsel also pointed out,
    however, that Plaintiff's expert designation for Dr. Haftel did not disclose that he would
    advocate the SIRS plus infection definition of sepsis or that he would opine that any
    patient that presents with symptoms meeting that definition of sepsis must be
    hospitalized. Our review of the expert designations for Drs. Haftel and Bernhisel
    confirms that neither designation addressed these opinions. Plaintiff's designation of Dr.
    Haftel did not attach an expert's report, and instead specified that Dr. Haftel would testify
    to facts and matters contained in his deposition should one be taken. The designation
    further provided, in relevant part:
    Dr. Haftel is expected to testify as to his conclusions relating
    to the care and treatment provided to Connie Scribner while
    at the Emergency Department of the Wyoming Medical
    Center and under the care of emergency room physician, Dr.
    Beyer. He is expected to testify that Dr. Beyer's care fell
    below the accepted standard of care and that his failures
    ultimately led to Connie Scribner's death through a failure to
    properly treat her diagnosed bilateral pneumonia and failure
    to secure her admission to the hospital. * * * Based upon her
    presentation at the emergency department, her physical signs,
    blood work, vitals and x-rays she met admission requirements
    and should have been admitted to the hospital for care and
    22
    follow-up treatment. By failing to seek admission, Dr.
    Beyer's care fell below the standard of care.
    [¶53] Defendants’ designation of Dr. Bernhisel included an attached report that
    explained Dr. Bernhisel's review of Decedent's condition, treatment and death, set forth
    his opinion concerning the standard of care and his opinion that Defendants provided care
    in keeping with that standard, and set forth his opinions as to the cause of Decedent's
    death, which he did not attribute to Defendants' care. The designation of Dr. Bernhisel
    further provided, in relevant part:
    Dr. Bernhisel will testify in accordance with the
    applicable standards of care for emergency medicine
    physicians. He will testify that the care and treatment
    provided to Connie Scribner by the defendants met the
    standard of care.
    ****
    Additionally, Dr. Bernhisel may testify in rebuttal, on
    all issues, to any evidence presented by the plaintiff's expert
    or lay witnesses.
    [¶54] The district court ultimately was not concerned with the lack of specificity in
    Plaintiff's designation of Dr. Haftel's testimony because the court believed that
    Defendants had received adequate notice of Dr. Haftel's opinions from his testimony in
    the first trial. Our review of the transcripts confirms the court's recollection. Although
    not presented in precisely the same manner as in the second trial, Plaintiff during the first
    trial presented testimony from Dr. Haftel that an emergency room physician should know
    the SIRS plus infection definition of sepsis and that it was his opinion that if a patient is
    diagnosed with sepsis, that patient must be hospitalized.
    [¶55] Our review of the first trial also revealed, however, that Defendant Dr. Beyer
    testified during that trial that he does not agree with Dr. Haftel's opinion that any patient
    who is diagnosed with sepsis using the SIRS plus infection definition must be
    hospitalized. Dr. Beyer characterized the SIRS plus infection definition as "overly
    cautious" and "overly broad," and he cited studies that described the definition as a "poor
    prognostic indicator." The first trial ended in a mistrial before Dr. Bernhisel testified, so
    we do not of course know whether his testimony would have been along similar lines.
    Dr. Beyer's testimony was at least some notice to Plaintiff, though, that Defendants
    intended to challenge the usefulness of the SIRS plus infection definition of sepsis as a
    predictor of when hospitalization of a patient is required.
    23
    [¶56] We need not, however, necessarily resolve the question of the adequacy of
    Defendants' designation. On appeal, Plaintiff argues the district court abused its
    discretion in admitting Dr. Bernhisel's testimony because the testimony was an unfair
    surprise and an irregularity in the proceedings that led to juror confusion. We note,
    though, that despite Plaintiff's varying characterizations of the defects in the ruling, the
    prejudice that Plaintiff argues she suffered as a result of the admission all sounds in
    unfair surprise—specifically, that the undesignated testimony surprised Plaintiff and
    made effective cross-examination, challenge and impeachment of the evidence
    impossible. Where the claim is one of unfair surprise, this Court has repeatedly held that
    "the appropriate response from a surprised party who wishes to counter testimony is a
    request for a continuance, and the failure to request one precludes a claim of prejudice."
    In re MC, 
    2013 WY 43
    , ¶ 48, 
    299 P.3d 75
    , 85 (Wyo. 2013) (quoting Betts v. Crawford,
    
    965 P.2d 680
    , 685 (Wyo. 1998)); see also Parrish v. Groathouse Constr. Co., 
    2006 WY 33
    , ¶ 15 n.4, 
    130 P.3d 502
    , 507 n.4 (Wyo. 2006) ("Since trial counsel did not request a
    continuance at the time the trial court overruled his objection, the objection of unfair
    surprise is effectively waived."); Meyer v. Rodabaugh, 
    982 P.2d 1242
    , 1245 (Wyo. 1999)
    (failure to request a continuance on the ground of surprise precludes a party from
    contending on appeal that he was prejudiced).
    [¶57] The district court approached the concerns with Dr. Bernhisel's testimony with
    great caution, and, while the court admitted Dr. Bernhisel's testimony, it also offered
    Plaintiff the option of taking a continuance at the conclusion of defense counsel's direct
    examination of Dr. Bernhisel. The court ruled:
    * * * I don't believe the plaintiff was properly advised
    of [Dr. Bernhisel's testimony]. And so the issue is how do we
    address that. I'm not going to strike the testimony. I'm
    certainly not going to declare another mistrial. But I will do
    this: At the conclusion of Dr. Bernhisel's testimony, I will
    allow plaintiffs additional time to prepare for cross-
    examination as they require. And that can be a reasonable
    time but not later than reconvening the trial Monday morning.
    So, basically – and I'll have the plaintiffs tell me at the
    conclusion of the trial, out of the presence of the jury, how
    much additional time they wish to prepare, later this
    afternoon, tomorrow morning, tomorrow afternoon, or
    Monday morning, but not later than Monday morning.
    [Plaintiff's Counsel]: Okay.
    THE COURT: And that's to give them additional time not
    only to prepare for cross-examination and do such
    24
    consultation as they need, if they need some; but in addition,
    to determine whether they want to present rebuttal testimony.
    Now, obviously, I'm not directing that they take
    additional time, but I'm giving the opportunity to request that.
    [¶58] At 10:39 a.m. on Wednesday, March 27, of the second trial, Defendants completed
    their direct examination of Dr. Bernhisel. At 10:50 that morning, Plaintiff's counsel
    declined the continuance and proceeded with cross-examination of Dr. Bernhisel. Setting
    aside the questions of whether Defendants properly designated Dr. Bernhisel's testimony
    and whether Plaintiff was in fact surprised by Dr. Bernhisel's testimony, Plaintiff not only
    did not request a continuance but turned down a continuance that could have extended
    from Wednesday morning to Monday morning. Under these circumstances, Plaintiff has
    waived any claim of prejudice related to the asserted surprise of Dr. Bernhisel's testimony
    concerning the clinical value of the SIRS plus infection definition of sepsis.
    Dr. Bernhisel's Testimony Re: PORT and CURB-65
    [¶59] As noted above, Dr. Bernhisel testified that the PORT and CURB-65 pneumonia
    severity indices were better predictors of whether a pneumonia patient requires
    hospitalization and that Dr. Beyer's decision to discharge Decedent was in keeping with
    the PORT and CURB-65 guidelines. Plaintiff objected to Dr. Bernhisel's testimony
    concerning PORT and CURB-65 and its application to Dr. Beyer's discharge decision on
    the grounds reflected in the following exchange:
    [Defense Counsel]: * * * And then, also, Your Honor, with
    the CURB-65, that – like we said before, that was part of Dr.
    Bernhisel's deposition. There is over nine pages where Mr.
    Ulmer asked Dr. Bernhisel how the PORT score and the
    CURB-65 score are used in the clinical setting.
    THE COURT: Okay. He didn't object on that ground.
    ****
    [Plaintiff's Counsel]: My objection with respect to the PORT
    score was – was that – not that it wasn't designated. It was.
    ****
    [Plaintiff's Counsel]: My objection related to 403 and
    relevance and that it was confusing and misleading because it
    wasn't something used at the time. And so it shouldn't be
    25
    allowed to the jury to have them make a determination that,
    oh, Dr. Beyer was thinking all of the right things when he
    made his decisions, because he didn't use it. So that is – that
    is the objection on the PORT score.
    [¶60] The district court allowed Dr. Bernhisel's testimony over Plaintiff's objection, as
    follows:
    First of all, I'm going to allow Dr. Bernhisel –
    Bernhisel – if I'm pronouncing it correctly – to testify
    regarding the PORT scores. I understand that it is an after-
    the-fact test that is being used to say that his clinical judgment
    was correct. And if the – I think that can be brought out
    clearly on cross-examination. And if the plaintiffs want an
    instruction to that effect, then they should draft that
    informally, and I'll give that. That takes care of that issue.
    [¶61] Before the jury began their deliberations, the court gave Instruction No. 24, which
    instructed the jury on the PORT and CURB-65 testimony:
    There has been testimony about PORT scores and
    CURB 65 scores during this trial. These are methods
    sometimes used to analyze pneumonia symptoms. Testimony
    concerning these methods is not intended to say that Dr.
    Beyer properly applied such methods in his care and
    treatment of Connie Scribner and the testimony shall not be
    considered by you as such. The weight of this testimony
    concerning these methods is for you to decide.
    [¶62] During Dr. Bernhisel's testimony, Plaintiff further objected to testimony
    concerning CURB-65, and in particular Dr. Bernhisel's testimony concerning Decedent's
    BUN levels, on grounds that the testimony called for speculation and was outside Dr.
    Bernhisel's designation. The court again overruled Plaintiff's objection.
    [¶63] On appeal, Plaintiff instead argues that the CURB-65 testimony, by both Dr.
    Beyer and Dr. Bernhisel, was a "well organized and preconceived ambush." Plaintiff
    further argues that Dr. Bernhisel lacked expertise in application of CURB-65 and she was
    precluded in showing this through cross-examination because of the surprise nature of the
    testimony. Regarding the surprise nature of Dr. Bernhisel's testimony, Plaintiff argues on
    appeal:
    Dr. Bernhisel's report does make mention of the
    existence of CURB-65 as such a metric but does not discuss it
    26
    in the body of his report or in his deposition. At the time, he
    was more taken with the PORT Score criteria that he
    presumably had to abandon because Dr. Beyer had not done
    enough of the lab tests to obtain a score for Connie Scribner.
    [¶64] Our review of the record indicates that Dr. Bernhisel did in fact discuss CURB-65
    in his deposition. During his deposition taken by Plaintiff's counsel, Dr. Bernhisel
    testified, in part:
    Q. * * * Is there any lab or study that can be done that would
    give the emergency room doctor an understanding of the
    severity of the pneumonia?
    A. Well, your clinical judgment's probably one of the critical
    things, but we do have some guidelines that have been drawn
    up and studied that look at that that give us some information
    that we can use, in addition to our clinical judgment, to
    determine how we treat these patients and who can we treat as
    an inpatient, who do we treat as an outpatient. So we do have
    some guidelines that we use on a regular basis.
    Q. Are those like the pneumonia severity indexes?
    A. The two that we use the most are the PORT score and the
    CURB-65. Those are the two that – at the University of Utah,
    and I believe nationally, are used probably of the most
    frequently for pneumonia.
    [¶65] This testimony by Dr. Bernhisel was followed by several pages of further
    examination by Plaintiff's counsel concerning CURB-65 and PORT. Dr. Bernhisel's
    testimony concerning PORT and CURB-65 was therefore in keeping with his expert
    designation. We therefore find no abuse of discretion in the district court's admission of
    Dr. Bernhisel's testimony. 2
    2
    Additionally, we note again that even if Plaintiff was surprised by Dr. Bernhisel's testimony, Plaintiff
    failed to request a continuance. Thus, Plaintiff's claims of prejudice relating to the alleged surprise
    testimony, namely an inability to effectively impeach and confront the testimony, are waived by her
    failure to request a continuance. See In re MC, ¶ 48, 299 P.3d at 85. Finally, although Plaintiff argues
    jury confusion as a result of the district court's rulings on Dr. Bernhisel's testimony, those claims likewise
    seem to stem from unfair surprise and the resulting inability to properly confront Dr. Bernhisel's
    testimony. They do not stem from the ground argued at trial that the testimony regarding PORT and
    CURB-65 was confusing and misleading because Dr. Beyer used neither guideline in treating Decedent
    and making his discharge decision. Certainly, Plaintiff has presented no argument on appeal as to how
    the district court's instruction was in any way inadequate to address the concerns related to Dr. Beyer's
    27
    b.     Dr. Beyer's Testimony
    [¶66] As noted above, Defendant Dr. Beyer testified that application of the CURB-65
    criteria to Decedent's symptoms on October 20 supported his discharge decision. This
    testimony occurred during Plaintiff's direct examination of Dr. Beyer in her case in chief.
    Plaintiff's counsel asked the first question regarding CURB-65 early in his direct
    examination of Dr. Beyer.
    Q. And do you remember [Defense Counsel] was asking Dr.
    Haftel about the CURB-64 [sic]? Do you remember him
    asking that?
    A. Yes.
    Q. And that's a – kind of a pneumonia severity index;
    correct?
    A. That is correct.
    Q. And you don't use pneumonia severity indexes in your
    practice; correct?
    [Defense Counsel]: Actually, I asked him about CURB-65.
    [Plaintiff's Counsel]: Thank you. CURB-65.
    Q. You don't – the CURB-65 is a pneumonia severity index;
    correct?
    A. Correct.
    Q. And you don't use pneumonia severity indexes in your
    practice; correct?
    A. Not – not very often; that is true.
    [¶67] The next day, during his continuing direct examination of Dr. Beyer, Plaintiff's
    counsel asked Dr. Beyer about his ability to determine how Decedent's body was
    functioning internally without performing tests, and the following exchange occurred:
    use or non-use of the guidelines in making his discharge decision. We therefore do not give that claim
    any further consideration.
    28
    Q. And those things are things that you can't tell just by
    looking at somebody; true?
    A. True.
    Q. Okay.
    A. But there are – there are a set of – of prognostic criteria
    set forth that give you – that predict mortality for community-
    acquired pneumonia.
    Q. Now –
    A. The CURB-65. The CURB-65.
    Q. Perfect. Perfect. Let's talk about that again, because I
    want to go back to that. And I would like to –
    [THE COURT]: [Plaintiff's Counsel], before we start a new
    topic, I wonder if this would be a good time for a break.
    ****
    Q. Okay. Right before we took a break, you mentioned that
    there is other prognosticators, like the CURB-65; correct?
    A. Correct.
    Q. But yesterday when we talked, you said that you didn't
    use the CURB-65 when you were treating Connie Scribner.
    Do you recall that testimony?
    A. Correct.
    Q. All right. And that's true; correct?
    A. Correct.
    Q. And that you don't use at all in your practice any kind of
    pneumonia severity index; true?
    A. Correct.
    29
    [¶68] Defendant Dr. Beyer also testified to the following on direct examination by
    Plaintiff's counsel:
    Q. But in terms of recognizing problems – and you're talking
    about pneumonia – but the problems that are associated with
    sepsis, those are problems that require medical monitoring
    that cannot be done by the average person at home; correct?
    A. Correct.
    Q. Right.
    And that is why, when somebody presents in the
    emergency department with a bilateral pneumonia and sepsis,
    they are not sent home; they are admitted to the hospital –
    A. That is not –
    Q. -- where they are monitored?
    A. That is not always the case. It's not.
    Q. It's not what you did?
    A. It's not what I did. My – that is correct. My judgment
    was to discharge her. And there are – you know, there are
    good studies showing that that is appropriate in some cases.
    And she qualifies actually as one of those patients that can be
    given a safely discharged home to be monitored.
    Q. Well, okay.
    The studies that you just referenced saying that she
    was somebody who could be safely sent home to be
    monitored, those aren't studies that you had available to you,
    consulted with, looked at, considered when you made the
    decision to take and send Connie Scribner home; correct?
    A. That is true. They do confirm my clinical impression at
    the time of discharge.
    30
    [¶69] During cross-examination by defense counsel, Dr. Beyer testified as follows,
    without objection:
    Q. [Plaintiff's Counsel] was talking to you about what
    appears to be a continuum, an ongoing study of individuals
    with pneumonia and the relationship that that pneumonia has
    to sepsis and severe sepsis.
    A. Yes.
    Q. Why is there such a continual amount of attention paid to
    that particular subject?
    A. Because it's – you know, it's a very frustrating thing to
    treat. It is – we're constantly trying to come up with new
    ways to treat it better and diagnose it. And so there is a lot of
    research going on in this – in this field.
    Q. In the field, what has been the result of this definition?
    A. This definition has been shown to be, again, overly broad;
    and particularly in the case of community-acquired
    pneumonia, the CURB-65 criteria have been shown compared
    to SIRS plus sepsis, that those – that those exact symptoms –
    or symptom complexes and the studies have been done
    comparing the two in terms of prognosis. And the CURB-65
    trial has been – has shown that the CURB-65 is much better
    at predicting mortality and outcome in community-acquired
    pneumonia as opposed to using the SIRS plus sepsis more
    general criteria.
    Q. SIRS plus sepsis, does that result in a large number of
    unnecessary admissions?
    A. Yes, it does.
    Q. And so to cut down on the unnecessary admissions, you
    identify the dangerous cases. Is that the reason for the study?
    A. Yes. They were trying to – this was in the journal Thorax
    from the Britain's thoracic society, and it's a – they found that
    – that was one of their purposes, was to compare a lot of the –
    the symptom complexes and symptoms to try to figure out
    31
    what is the best way to –to find that balance between treating
    – you know, admitting appropriately too often versus
    discharging folks you don't want to discharge. And, actually,
    that study showed that the CURB-65 criteria are better at both
    predicting those patients that are going to get worse and is
    also better at predicting those that are going to – are not going
    to – are – are going to get better that the SIRS plus an
    infection.
    [¶70] On continued cross-examination by defense counsel, Dr. Beyer testified
    concerning application of the CURB-65 criteria, including his conclusions concerning
    Decedent's blood urea nitrogen level as it related to the "U" in the CURB-65 analysis.
    Q. All right. And the urea would be the BUN that we just
    discussed?
    A. Would be the BUN, correct.
    Q. Connie's BUN when she presented in full cardiac arrest at
    the emergency room was normal?
    A. It was normal.
    Q. And so what does that tell you what it would have been 24
    hours before that?
    A. It would be normal.
    [Plaintiff's Counsel]: Object; calls for speculation.
    THE COURT: Well, wait.
    [Defense Counsel]: I was going to clear up the speculation if
    I could.
    Q. Can you make an extrapolation based upon your
    education, training, and experience about whether a normal
    urea on the day that she is in cardiac arrest would be normal
    24 hours before that?
    A. Yes. In theory –
    32
    [Plaintiff's Counsel]: Your Honor, I'm going to offer an
    objection. If he wants to talk about it, I guess during the
    direct, that's fine. But this is beyond the scope of my cross.
    And I think that we're getting into an area that's also never
    been designated from the witness.
    THE COURT: Was this witness designated as an expert? I
    can't remember.
    [Defense Counsel]: Well, Your Honor, he's the defendant in
    the case.
    THE COURT: I know.
    [Defense Counsel]: And he –
    THE COURT: Does he have to be designated?
    [Defense Counsel]: Well, I haven't designated him as an
    expert witness, but –
    THE COURT: You may ask the question. Go ahead.
    Q. Can you extrapolate 24 hours before that?
    A. Yes. I mean, if this – if Connie, when she arrived in the
    hospital on the 21st, was – had – unconscious, was having
    CPR done, if this would have been due to severe septic shock,
    the BUN creatinine should be abnormal. And so if it was
    normal when she was in this much extremis, then you can
    pretty much assuredly say it was normal the previous day.
    [¶71] On redirect examination by Plaintiff's counsel, the following exchange took place:
    Q. You had mentioned this article from Thorax. Do you
    recall that, the British magazine?
    A. Yes.
    Q. When did you review that?
    A. In the last few days.
    33
    Q. Okay. And so you hadn't reviewed the article about
    Thorax and CURB-65 and its relation to SIRS and its relation
    to sepsis at any time prior to your treatment of Connie
    Scribner; correct?
    A. Correct.
    Q. And, in fact, we talked about the fact that the CURB-65 is
    not even something that you use; correct?
    A. Correct. It does –
    THE COURT: Wait a minute.
    Q. Just a second.
    [Plaintiff's Counsel]: Your Honor, I think that I would move
    to strike any testimony about the BUN and the CURB-65,
    anything directing the Thorax article as having been
    undesignated testimony. He's offering it as an expert witness,
    and it's never been designated.
    [Defense Counsel]: Your Honor, he is simply defending
    himself in a medical malpractice case. And I think that that
    information is relevant. He's entitled to do his research of the
    literature in his own defense, and that's what he did.
    THE COURT: I will not strike the testimony.
    [¶72] The Court did not strike the testimony, but Plaintiff's counsel was permitted the
    opportunity to review the Thorax article and examine Defendant Dr. Beyer concerning
    the article when Dr. Beyer was called during Defendants' case. After additional
    testimony on redirect examination of Dr. Beyer by Plaintiff's counsel, Plaintiff's counsel
    again objected to Dr. Beyer's testimony concerning CURB-65 and moved to strike the
    testimony:
    [Plaintiff's Counsel]: Your Honor, once again, I would move
    to strike the testimony regarding CURB-65 because it is not
    something that he used in his care and treatment of Connie
    Scribner; and to talk about it as justification for his care and
    treatment now is confusing and highly prejudicial, and it
    shouldn't be something that the jury would have to – to wade
    through in their deliberations.
    34
    [¶73] The court again overruled Plaintiff's objection and denied the motion to strike.
    The court then gave the following instruction to the jury:
    I'm going to instruct the jury that the doctor is not
    testifying that he relied upon this CURB-65 or the CRB-65
    when he made his decision to discharge Ms. Scribner. That is
    not the basis for his testimony. He is only saying that it
    confirms that what he did was right. Now, that is ultimately
    your decision, but you are to consider testimony on this
    CURB-65 only for that limited purpose.3
    [¶74] On appeal, Plaintiff argues that the district court abused its discretion in admitting
    Dr. Beyer's testimony concerning CURB-65 and Decedent's BUN levels because 1) the
    testimony was undesignated expert testimony that unfairly surprised Plaintiff; and 2) the
    testimony misled and confused the jury concerning the standard of care. We disagree
    that Dr. Beyer's testimony should have been excluded as undesignated expert testimony,
    and we also reject Plaintiff's contention that the testimony should have been excluded as
    misleading or confusing.
    [¶75] Rule 26(a) of the Wyoming Rules of Civil Procedure did not require designation
    of Defendant Dr. Beyer's testimony. Rule 26(a) provides, in relevant part:
    (2) Disclosure of expert testimony.
    (A) In addition to the disclosures required by
    paragraph (1) or (1.1), a party shall disclose to other parties
    the identity of any person who may be used at trial to present
    evidence under Rules 702, 703, or 705 of the Wyoming Rules
    of Evidence.
    (B) Except as otherwise stipulated or directed by the
    court, this disclosure shall, with respect to a witness who is
    retained or specially employed to provide expert testimony in
    the case or whose duties as an employee of the party regularly
    involve giving expert testimony, be accompanied by a written
    report prepared and signed by the witness or disclosure signed
    by counsel for the party. The report or disclosure shall contain
    a complete statement of all opinions to be expressed and the
    basis and reasons therefor; the data or other information
    considered by the witness in forming the opinions; any
    3
    This instruction is in addition to the earlier-referenced written instruction the court read to the jury
    before it began its deliberations.
    35
    exhibits to be used as a summary of or support for the
    opinions; the qualifications of the witness, including a list of
    all publications authored by the witness within the preceding
    ten years; the compensation to be paid for the study and
    testimony; and a listing of any other cases in which the
    witness has testified as an expert at trial or by deposition
    within the preceding four years.
    (C) These disclosures shall be made at the times and in
    the sequence directed by the court. In the absence of other
    directions from the court or stipulation by the parties, the
    disclosures shall be made at least 90 days before the trial date
    or the date the case is to be ready for trial or, if the evidence
    is intended solely to contradict or rebut evidence on the same
    subject matter identified by another party under paragraph
    (2)(B), within 30 days after the disclosure made by the other
    party. The parties shall supplement these disclosures when
    required under subdivision (e)(1).
    W.R.C.P. 26(a)(2) (emphasis added).
    [¶76] Defendants' expert witness designation stated that "Defendants reserve the right to
    elicit expert testimony from treating physicians to the extent that those physicians have
    opinions within their fields of expertise which relate to the issues of liability and
    causation in this case." Defendants thus identified Defendant Dr. Beyer as a witness who
    "may be used at trial to present evidence under Rules 702, 703, or 705 of the Wyoming
    Rules of Evidence," as required by Rule 26(a)(2)(A). Beyond that, no further designation
    was required. Rule 26(a)(2)(B), by its plain terms, applies to witnesses retained or
    specially employed to provide expert testimony in a case. Dr. Beyer was neither. He was
    a defendant, not an expert retained or employed to provide testimony.
    [¶77] Moreover, we have held that a party cannot seek to exclude evidence when he
    "opens the door" to inquiry about it. See Roden v. State, 
    2010 WY 11
    , ¶ 14, 
    225 P.3d 497
    , 501 (Wyo. 2010); Lawrence v. State, 
    2007 WY 183
    , ¶ 14, 
    171 P.3d 517
    , 521-22
    (Wyo. 2007). Plaintiff's counsel called Dr. Beyer as a witness in Plaintiff's case-in-chief
    and explored all manner of opinion testimony including the definition of sepsis, the
    requirement that a physician know how to identify sepsis, the progression of sepsis, rules
    an emergency room physician must follow in treating any patient, and the standard of
    care as to when a pneumonia patient must be hospitalized. Additionally, as to Decedent's
    BUN level, Plaintiff's counsel asked Dr. Beyer how he could know how Decedent's
    bodily functions were performing, such as her kidneys, without having requested the
    specific lab tests on the date he saw her in the emergency room. Plaintiff's counsel asked
    a similar line of questions concerning how Dr. Beyer could know whether there were any
    36
    signs or symptoms of severe sepsis if he had not requested the specific lab tests when he
    saw her. Having opened the door to Dr. Beyer's opinions, Plaintiff was not in a position
    to seek exclusion of the relevant testimony.
    [¶78] Finally, on the question of unfair surprise, the district court made allowances for
    Plaintiff's counsel to review the article relied upon by Dr. Beyer in his testimony, and
    gave him leeway to further examine Dr. Beyer on the article when Dr. Beyer was called
    in Defendants’ case. At trial, Plaintiff's counsel commented on that relief, stating, "I
    would say that – Your Honor, that Dr. Beyer talked about CURB-65 being a better
    predictor of mortality than SIRS. And I'm aware of that. And I had the weekend to read
    it. And I am prepared on that." It is apparent that to the extent Plaintiff felt blind-sided
    by Dr. Beyer's CURB-65 testimony, the court adequately addressed that issue at trial. To
    the extent that Plaintiff asserts any further prejudice as a result of unfair surprise, such as
    the ability to impeach Dr. Beyer's reliance on a particular article or the ability to fully
    confront Dr. Beyer's extrapolation of BUN values and the significance of those values,
    we find these claims to be waived by Plaintiff's failure to request a continuance. See also
    Parrish, ¶ 15 n.4, 130 P.3d at 507 n.4 ("Since trial counsel did not request a continuance
    at the time the trial court overruled his objection, the objection of unfair surprise is
    effectively waived.").
    [¶79] We turn last to Plaintiff's argument that Dr. Beyer's testimony should have been
    excluded as misleading and confusing to the jury on the question of the standard of care.
    In making this argument, Plaintiff cites to 
    Wyo. Stat. Ann. § 1-12-601
    , which sets forth a
    plaintiff's burden of proof in a medical malpractice action. In particular, the provision
    requires that a plaintiff prove that the defendant physician "failed to act in accordance
    with the standard of care adhered to by that national board or association." 
    Wyo. Stat. Ann. § 1-12-601
    (a)(i) (LexisNexis 2013). Based on this provision, Plaintiff argues that
    Dr. Beyer's testimony was confusing and misleading because the testimony advocated for
    a standard of care that was not followed by Dr. Beyer and was based on a study published
    in 2006, after Dr. Beyer's treatment and discharge decisions in the care of Decedent.
    [¶80] Plaintiff's argument is flawed for the fundamental reason that it attempts to shift
    the burden of proof. In a medical malpractice action, it is clear that a plaintiff carries the
    burden of establishing: 1) the standard of care; and 2) that the defendant physician
    deviated from that standard of care. Id.; Witherspoon v. Teton Laser Center, LLC, 
    2007 WY 3
    , ¶ 16, 
    149 P.3d 715
    , 726-27 (Wyo. 2007). A defendant is not required to establish
    the standard of care.
    [¶81] In this case, Plaintiff asserted that the definition of sepsis is SIRS plus infection
    and that the standard of care required hospitalization of any pneumonia patient meeting
    that definition. The studies cited by Dr. Beyer, and by Dr. Bernhisel, showed that the
    standard of care asserted by Plaintiff was not supported by studies of pneumonia patients
    and their responses to sepsis. The studies otherwise showed that other guidelines are
    37
    better predictors of mortality among pneumonia patients. That evidence was relevant to
    rebut Plaintiff's proffered standard of care. Dr. Beyer's testimony, again echoed by Dr.
    Bernhisel, was not that Dr. Beyer followed the alternative guidelines, but rather that his
    exercise of clinical judgment was consistent with these guidelines. This too was relevant
    to rebut Plaintiff's evidence that Dr. Beyer deviated from the standard of care.
    [¶82] The district court's repeated instructions to the jury that testimony concerning
    alternative guidelines was not testimony that Dr. Beyer followed those particular
    guidelines adequately guarded against any confusion that could arise from either Dr.
    Beyer's or Dr. Bernhisel's testimony. We find no abuse of discretion in the admission of
    Dr. Beyer's testimony concerning CURB-65 or Decedent's extrapolated BUN levels.
    CONCLUSION
    [¶83] The district court did not abuse its discretion in declaring a mistrial or in admitting
    the testimony of Defendant Dr. Beyer and Defendants' emergency medicine expert
    specified in Plaintiff's statement of her issues on appeal. Affirmed.
