    OPINION
    By the Court, SILVER, J.:
    When a juror is biased against a party, that juror must be
    struck from the jury. In this appeal, we consider whether the district
    court erred in declining to strike an empaneled juror whose background

    experience implied bias but who asserted he could be impartial. We also
    consider the district court's decisions to invite challenges for cause with
    the juror present and to allow a newly discovered document to be entered
    into evidence and testified to on the final day of trial. We hold the district
    court erred in these respects and, accordingly, we reverse and remand for
    a new trial.
    FACTS AND PROCEDURE
    This appeal arises from a jury trial on a personal injury claim
    for damages following a 2009 car accident. Respondent Risa Sears-Page
    made a right turn from a left-hand lane and hit appellant Toni Sanders'
    car. Initially, the accident appeared minor as neither party claimed
    injuries at the scene. A few days later, Sanders purportedly began
    experiencing neck pain that worsened over time. Sanders and her
    husband, appellant Robert Sanders, sued Sears-Page for negligence to
    recover damages, including medical expenses. Sears-Page admitted
    liability but denied causation and damages.
    Sanders' injuries
    The central issues at trial involved whether the accident had
    caused or contributed to Sanders' injury and, if so, whether Sanders'
    claimed medical expenses were reasonable. Sanders, who had chronic
    back pain, had previously experienced neck pain in 2004 from a bone spur.
    But she denied having neck pain in the years immediately preceding the
    accident, and two of her treating physicians testified the accident with
    Sears-Page caused Sanders' 2009 neck pain. Both doctors also testified
    Sanders' medical procedures and surgeries following the accident to
    alleviate pain were reasonably necessary.
    To support her claimed damages, Sanders presented medical
    records and bills from Nevada Spine Clinic. Those records were generated
    COURT OF APPEALS
    OF
    NEVADA
    2
    (0) 1947B
    primarily by treatment from Doctors Jaswinder Grover, Babuk Ghuman,
    and Jorg Rosler, but many records were generated by other doctors and
    medical professionals at Nevada Spine Clinic. Of the people who treated
    Sanders at Nevada Spine Clinic, only Dr. Grover testified at trial. Dr.
    Grover was one of several doctors at that clinic who treated Sanders for
    chronic back pain before the 2009 accident and also treated her for neck
    pain after the accident, and testified all of Sanders' medical bills from
    Nevada Spine Clinic were reasonable.
    Sears-Page denied Sanders' injuries occurred as a result of the
    automobile accident. Instead, Sears-Page asserted Sanders' symptoms
    arose from a preexisting degenerative medical condition. In opening
    statements, Sears-Page emphasized that Dr. Grover "sold [Sanders] spine
    surgery" and the doctors at Nevada Spine Clinic encouraged unnecessary
    surgery and medical procedures for their own financial gain. Sears-Page
    argued she should not have to pay for Sanders' unnecessary medical
    expenses, which were purposely inflated by Nevada Spine Clinic.
    During trial, Sears-Page's retained medical experts, Dr.
    Joseph Schifini and Dr. Derek Duke, both testified Sanders' medical
    records showed a preexisting degenerative condition that developed over
    the course of several years, and her post-accident medical records were
    devoid of trauma to her neck. Both experts opined the accident did not
    cause Sanders' medical condition or contribute to her current neck pain.
    Dr. Duke further noted Sanders' medical history prior to the accident
    included treatment for neck pain in 2004 and 2009, which supported his
    opinion that Sanders' degenerative condition alone caused her current
    neck pain.

    Both experts testified Sanders' surgery and medical
    procedures performed by Nevada Spine Clinic doctors were unnecessary
    and unreasonable. Further, they emphasized the clinic doctors' fees were
    significantly higher than average doctor's fees. Sears-Page argued Nevada
    Spine Clinic's physicians' practice of referring patients (like Sanders) to
    medical facilities owned by the physicians not only benefited the
    physicians financially, but also inflated Sanders' medical bills.
    Juror 9
    After opening statements and the testimony of Robert
    Sanders, Juror 9 notified the district court he previously had been a
    patient of Dr. Ghuman's at Nevada Spine Clinic. Because neither party
    mentioned Nevada Spine Clinic or Dr. Ghuman by name during voir dire,
    and the attorneys did not question Juror 9 regarding the names of his
    treating physicians for the back pain he disclosed during voir dire, Juror 9
    was unaware of the connection until after opening statements.
    Outside the presence of the other jurors, the district court and
    the attorneys questioned Juror 9. Juror 9 acknowledged several doctors at
    Nevada Spine Clinic treated him for a herniated disc. After an initial
    consultation with Dr. Ghuman, he was ultimately treated by other doctors
    at Nevada Spine Clinic who did not treat Sanders. When one of those
    doctors advised Juror 9 back surgery was "inevitable" and encouraged him
    to schedule surgery, Juror 9 sought a second opinion from a doctor at a
    different facility regarding back surgery. Juror 9 followed the advice of
    the second doctor and opted for nonsurgical treatments.
    Juror 9 stated he could be impartial "without a doubt," would
    "base [his] decision on facts," and would not "be inclined to give more
    credibility" to the conclusions of the doctors at Nevada Spine Clinic. When
    specifically questioned whether his experience might bias him against the
    COURT OF APPEALS
    OF
    NEVADA
    4
    (0) 1947B
    doctors at Nevada Spine Clinic, however, Juror 9 told the court, "I don't—I
    don't think so" and "I think I can keep an open mind." When Juror 9 was
    questioned regarding his ability to be impartial when viewing Nevada
    Spine Clinic's billing records, Juror 9 stated he had no problem with the
    billing from the clinic because he "didn't pay the bills anyway," referring to
    his insurance. Juror 9 advised the court he viewed "surgery as a last
    resort" and had "never been real enamored with having surgery."
    Additionally, Juror 9 stated he conducted "some research on fusion versus
    disc replacement" when deciding whether to have back surgery, and
    stated, "I kind of know which way I'm personally going to be
    leaning . . . [a]s far as my case." Neither the judge nor the attorneys asked
    Juror 9 about the nature or extent of his independent research.
    With Juror 9 still present, the district court asked the parties
    if either wished to challenge Juror 9 for cause. Sears-Page stated she did
    not, but Sanders challenged Juror 9 for cause. The district court then
    asked Juror 9 to leave the courtroom, and Sanders argued for striking
    Juror 9. Although Sears-Page told the court the juror appeared to be
    impartial, Sears-Page also acknowledged there was an issue of bias.
    Additionally, Sears-Page characterized Sanders' arguments for striking
    Juror 9 as "good," and suggested the district court make Juror 9 an
    alternate instead of removing him for cause. The court denied Sanders'
    motion to strike Juror 9 for cause, stating Juror 9's answers demonstrated
    his ability to be impartial. Juror 9 later became the foreman of the jury.
    Exhibit 62
    Prior to trial, both parties sought medical records from Dr.
    Pollard, who was unaffiliated with Nevada Spine Clinic and treated
    Sanders between 2004 and the accident, but Dr. Pollard only provided
    incomplete medical records in response. Both sides demanded Dr. Pollard
    COURT OF APPEALS
    OF
    NEVADA
    5
    (0) 1947B
    produce additional records prior to the close of discovery, but he failed to
    comply with those requests. Neither party sought an order to show cause
    for contempt from the discovery commissioner regarding this issue.
    Instead, the parties proceeded to trial with the incomplete records.
    During the week of trial, however, Sears-Page threatened Dr.
    Pollard with contempt if the complete records were not produced. Then,
    on the morning of the last day of trial, an unidentified person dropped off
    a box of documents at the courthouse to a member of Sears-Page's legal
    team. One of the documents was allegedly a portion of a medical record
    from a visit Sanders made to Dr. Pollard in 2005. That document stated
    Sanders suffered from "spinal degenerative joint disease and upper
    cervical area with bone spur." Yet, Sanders testified in her case-in-chief
    that she had not sought treatment for neck pain in 2005.
    Sears-Page sought to introduce this document into evidence
    and proposed to the district court that Dr. Duke, one of Sears-Page's
    retained medical experts, authenticate the document. Sanders objected to
    the document's admission, but the district court admitted the document as
    exhibit 62 because the court felt this result was fair given Sears-Page's
    aggressive tactics to obtain the records during the trial proceedings.
    Dr. Duke viewed exhibit 62 for the first time on the witness
    stand. He testified the document looked like a typical medical record. He
    then reviewed the document and opined that it supported his theory that
    Sanders had a chronic, degenerative disease that predated the 2009
    automobile accident and was the sole cause of her neck pain.
    The jury unanimously found for Sears-Page. Sanders appeals.
    ANALYSIS
    The issues we consider on appeal are whether the district
    court erred in (1) failing to strike Juror 9 for cause, (2) inviting challenges
    COURT OF APPEALS
    OF
    NEVADA
    6
    (0) 1947B
    for cause while Juror 9 was present, (3) admitting exhibit 62, and (4)
    allowing Dr. Duke to give undisclosed opinions based on exhibit 62. 1 We
    agree that in all four instances the district court erred and its errors are
    reversible. 2
    Sanders' challenge to Juror 9 for cause
    Sanders argues the district court erred in failing to remove
    Juror 9 for cause because Juror 9's statements suggested bias and he did
    not unequivocally state he could be impartial. We agree.
    The Nevada Constitution, like the U.S. Constitution,
    guarantees litigants the right to a jury trial. Nev. Const. art. 1, § 3; see
    U.S. Const. amend. VII. "The right to trial by jury, if it is to mean
    anything, must mean the right to a fair and impartial jury." McNally v.

    , 1018 (1969). "The
    importance of a truly impartial jury, whether the action is criminal or
    civil, is so basic to our notion of jurisprudence that its necessity has never
    really been questioned in this country." Whitlock v. Salmon,

    1 We do not address the remaining issues on appeal, including
    Sanders' arguments regarding attorney misconduct, the proposed jury
    instructions, and the eggshell plaintiff instruction. Insofar as the
    proposed jury instruction on apportionment of damages raises a purely
    legal question, we note the district court instructed the jury on
    aggravation of damages and appellants cite no Nevada law requiring the
    district court to also instruct the jury on apportionment of damages where
    there is only one alleged tortfeasor.
    2 Withoutcommenting on the merits of Sanders' arguments, we
    caution the parties to be mindful of the potential grounds for attorney
    misconduct.

    Nevada law is well-settled that whether a juror must be
    stricken for cause is a question of fact to be determined by the trial judge.
    Jitnan v. Oliver, 127 Nev. „ 
    254 P.3d 623
    , 628 (2011); see also NRS
    16.060 (providing that the district court tries all challenges to jurors for
    cause). Accordingly, we review a district court's denial of a challenge for
    cause to either a venireperson or a sworn juror for an abuse of discretion.
    See Jitnan, 127 Nev. at , 254 P.3d at 628-29; Blake v. State, 
    121 Nev. 779
    , 795-96, 
    121 P.3d 567
    , 578 (2005); see also Nelson v. Commonwealth,

    , 30-31 (Va. Ct. App. 2003) (applying the abuse of discretion
    standard to decisions regarding challenges for cause to both seated jurors
    and venirepersons).
    If a juror's statements suggest actual bias, the trial court must
    properly question the juror to determine if the juror will be impartial
    despite the bias. See Thompson v. Altheimer & Gray, 
    248 F.3d 621
    , 627
    (7th Cir. 2001) ("When a prospective juror manifests a prior belief that is
    both material and contestable . . . , it is the judge's duty to determine
    whether the juror is capable of suspending that belief for the duration of
    the trial." (emphasis omitted)). Actual bias arises where the juror's
    3Although   the right to an impartial jury has largely been addressed
    by our supreme court in a criminal context rather than in civil law, we
    note California's constitutional provision regarding the right to a jury trial
    is similar to ours, and California law has consistently extended the right
    of an impartial jury to civil litigants. See Weathers v. Kaiser Found.

    statements evince a biased state of mind that will prevent the juror from
    acting impartially. United States v. Torres, 
    128 F.3d 38
    , 43 (2d Cir. 1997);
    see State v. Squaires, 
    2 Nev. 226
    , 230-31 (1866) (defining actual bias).
    A juror's opinions or views for or against a party do not,
    without more, establish bias. See Kaplan v. State, 
    96 Nev. 798
    , 800, 
    618 P.2d 354
    , 355-56 (1980) (quoting Irvin v. Dowd, 
    366 U.S. 717
    (1961)); see
    also 
    Thompson, 248 F.3d at 625
    (noting that a juror's stated tendency to
    believe prison guards over inmates, without more, is not a sign of bias).
    Rather, bias exists when the juror's views either prevent or substantially
    impair the juror's ability to apply the law and the instructions of the court
    in deciding the verdict. See Preciado v. State, 130 Nev. , , 
    318 P.3d 176
    , 178 (2014); see also 
    Thompson, 248 F.3d at 625
    (holding that a prior
    belief becomes "bias only if it were irrational or unshakable, so that the
    prospective juror would be unable to faithfully and impartially apply the
    law" (internal quotation marks and emphasis omitted)).
    If the trial court sufficiently      questions the juror and
    determines the juror can set aside any bias and be impartial, we will
    generally defer to the trial court's decision. See Preciado, 130 Nev. at ,
    318 P.3d at 178 (discussing the standard of review in challenges for
    cause); 
    Thompson, 248 F.3d at 626-27
    (finding the district court's failure to
    sufficiently question a juror after the juror revealed potential bias
    constituted reversible error); see also United States v. Maloney, 
    699 F.3d 1130
    , 1137-38 (9th Cir. 2012) (discussing several cases where the jurors in
    question had experiences similar to the facts of this case and the district
    courts' questioning of those jurors was sufficient to show their
    impartiality), overruled on other grounds by United States v. Maloney, 
    755 F.3d 1044
    (2014).
    9
    Deference does not, however, mandate affirmance where
    failure to strike the juror was erroneous. See Jitnan, 127 Nev. at , 254
    P.3d at 629 (holding the district court abused its discretion in failing to
    strike a juror for cause). The Nevada Supreme Court has clarified that
    the district court should err in favor of seating an impartial jury whenever
    doubts remain as to the juror's impartiality. Bryant v. State, 
    72 Nev. 330
    ,
    333, 
    305 P.2d 360
    , 361 (1956). Recently, the court reaffirmed that a
    "prospective juror who is anything less than unequivocal about his or her
    impartiality should be excused for cause." Preciado, 130 Nev. at , 318
    P.3d at 177; see 
    Whitlock, 104 Nev. at 27
    , 752 P.2d at 212 ("The
    importance of a truly impartial jury, whether the action is criminal or
    civil, is so basic to our notion of jurisprudence that its necessity has never
    really been questioned in this country."). Thus, if the juror's statements,
    taken as a whole, indicate bias, the juror must be struck.     See Jitnan, 127
    Nev. at , 254 P.3d at 629.
    Our supreme court has never addressed a situation where a
    juror asserts impartiality despite having an experience so similar to the
    case being tried that the juror's impartiality is improbable. Other
    jurisdictions considering this question have determined that a juror's
    experience may directly impact the juror's ability to fairly judge the case,
    leading to bias. See, e.g., Kirk v. Raymark Indus., Inc., 
    61 F.3d 147
    , 156
    (3d Cir. 1995); Dyer v. Calderon, 
    151 F.3d 970
    , 975-76 (9th Cir. 1998). In
    such cases, reliance on the juror's promise of impartiality is insufficient
    when the record as a whole demonstrates lingering bias. See 
    Kirk, 61 F.3d at 156
    ; Wolfe v. Brigano, 
    232 F.3d 499
    , 502 (6th Cir. 2000).
    In Kirk, the United States Court of Appeals for the Third
    Circuit held that a juror who had inhaled asbestos, knew people who were
    COURT OF APPEALS
    OF
    NEVADA
    10
    (0) 1947B
    suffering from asbestos poisoning, and feared succumbing to an asbestos-
    induced disease, should not have been empaneled in an asbestos damages
    
    case. 61 F.3d at 156
    . The court held the juror's background gave rise to
    an inference of impermissible bias in favor of the plaintiffs, and the juror
    would be more likely to return a large award of damages because of his
    own experiences. 
    Id. Accordingly, the
    juror's statement of impartiality
    was insufficient to support the district court's denial of the challenge for
    cause. 
    Id. Likewise, in
    Wolfe, the Sixth Circuit determined a district
    court erred by accepting a juror's assertion of impartiality where the juror
    had a close relationship with the victim's family and had spoken to them
    about the 
    crime. 232 F.3d at 502
    . The Second Circuit in Torres upheld a
    district court's finding of bias where a prospective juror in a criminal trial
    engaged in similar conduct as the conduct with which the defendant was
    criminally 
    charged. 128 F.3d at 44-45
    . And in 
    Dyer, 151 F.3d at 975-76
    ,
    the Ninth Circuit held a trial judge erred in accepting a juror could be
    impartial in a murder trial where the juror's brother died under
    circumstances similar to those suffered by the victims.
    We agree with these jurisdictions and hold that if a juror's
    "background is replete with circumstances which would call into question
    his ability to be fair," the district court should remove the juror for cause,
    even if the juror has stated he or she can be impartial. 
    Kirk, 61 F.3d at 156
    . In determining whether to strike a juror for cause, the trial court
    should assess the actual facts of the juror's experience rather than rely
    solely upon the juror's assertion of impartiality.
    In opening statements, Sears-Page told the jury "Nevada
    Spine Clinic sold Sanders surgery" and further suggested Sanders wanted
    COURT OF APPEALS
    OF
    NEVADA
    11
    (0) 1947B
    to make Sears-Page pay hundreds of thousands of dollars for this
    unnecessary surgery. After opening statements, Juror 9 admitted to the
    district court and parties he, too, was a patient at Nevada Spine Clinic.
    The district court questioned Juror 9 and elicited Juror 9's promise he
    would try to be impartial. The trial judge accepted those assurances as
    reliable.
    It is well-established that trial judges are in the best position
    to view the prospective juror's demeanor and judge the veracity of the
    juror's assertion of impartiality, see Jitnan, 127 Nev. at , 254 P.3d at
    628-29, and therefore, in many cases, our inquiry would normally end
    here. Under the particular facts of this case, however, we conclude the
    district court nevertheless abused its discretion in failing to strike Juror 9
    for cause. Despite Juror 9's assertion of impartiality, his experience was
    "replete with circumstances which would call into question his ability to be
    fair," 
    Kirk, 61 F.3d at 156
    , and the record, read as a whole, suggests bias
    against the clinic's doctors and, by extension, Sanders' case.
    Juror 9's recent experiences with Nevada Spine Clinic bore
    striking similarity to Sanders', with the critical difference being Juror 9
    chose not to follow the clinic's advice. Juror 9 also expressly admitted he
    already determined "I kind of know which way I'm personally going to be
    leaning" under his own, and very similar, circumstances. Although Juror
    9 stated he would not discredit the opinions of the clinic's doctors, his
    decision to discredit the clinic's advice in his own case creates a strong
    inference Juror 9 would be unable to set aside bias in judging the facts of
    Sanders' case. This inference is critical because the crux of this case
    turned on competing expert opinions. The credibility of Sanders' case
    rested almost entirely on the evidence provided by the clinic. Neither the
    COURT OF APPEALS
    OF
    NEVADA
    12
    - (0) 194'7B
    court nor the parties asked any probing questions about Juror 9's opinions
    regarding the doctors or the clinic. The court simply denied Sanders'
    challenge based on Juror 9's superficial statement that he would try to be
    impartial.
    Moreover, Sears-Page's arguments during opening and closing
    statements emphasized the theory that the clinic's doctors "sold" Sanders
    unnecessary and overpriced surgery, along with other medical procedures.
    Because Juror 9 remained empaneled, Sears-Page benefited from making
    this argument to a juror who had been to the same clinic, seen one of the
    same doctors, 4 and been given the same advice to have surgery, but who
    instead researched alternatives to surgery and chose to disregard the
    clinic's opinion in favor of alternative, and inferably less expensive,
    nonsurgical treatments. In other words, this clinic failed to sell surgery to
    Juror 9. Juror 9's experience with this clinic significantly advantaged
    Sears-Page's ability to undermine the credibility of Sanders' experts and
    contest causation and damages.
    Additionally, Juror 9's statements claiming impartiality were
    not wholly unequivocal, supporting the implication of bias. Cf. Jitnan, 127
    Nev. at , 254 P.3d at 629 (detached language does not establish
    impartiality where the record otherwise indicates the juror could not
    unequivocally assure the court of his or her impartiality); see also
    Preciado, 130 Nev. at , 318 P.3d at 177 (holding that "a prospective
    4Although neither Dr. Hoffman nor Dr. Khavkin treated Sanders or
    were involved in the trial, the defense focused on the records generated by
    multiple doctors at Nevada Spine Clinic in arguing that Sanders'
    requested damages were unreasonable and inflated, effectively putting the
    medical opinions and billing practices of Nevada Spine Clinic as a whole at
    issue.

    juror who is anything less than unequivocal about his or her impartiality
    should be excused for cause"). Although Juror 9 did not state he doubted
    his ability to be impartial or he harbored bias, when directly questioned by
    the parties about whether his experience with the clinic would interfere
    with his ability to equally credit the evidence proffered by the clinic
    doctors, he qualified his statements regarding his ability to be impartial
    by responding, "I don't think so," and "I think I can keep an open mind."
    (Emphases added.) Further, Juror 9's statements that he did not have a
    problem with the clinic's billing practices because he did not have to pay
    the clinic's bills becomes particularly troublesome in light of defense
    counsel's continued arguments throughout trial that Sanders wanted
    Sears-Page to "pay for [her] surgery."
    Despite these facts, the district court refused to strike Juror 9
    for cause. This refusal is more disconcerting because the court later
    struck a juror who had dozed off for one to four minutes during the fifth
    day of trial. There, the juror was questioned separately and the juror
    assured the court she had been paying close attention and dozed for only a
    minute or two. Although neither party moved to strike that juror, the
    court sua sponte dismissed her. While we do not disparage the district
    court's determination to ensure the parties presented the case to an alert
    jury, we question why the court would remove a drowsy juror and not
    remove a juror whose background experiences unquestionably raised an
    inference of bias, to which both parties conceded. The court's sua sponte
    action of removing a drowsy juror while refusing to strike a juror whose
    background evinces bias is puzzling, particularly since there were
    sufficient alternates to replace both jurors.

    Because a review of the record as a whole casts serious doubt
    on Juror 9's ability to be fair and impartial, we hold the district court
    abused its discretion by failing to strike Juror 9 for cause.
    This error is reversible because Juror 9's presence on the jury
    resulted in an unfair empaneled jury.       See Jitnan, 127 Nev. at , 254
    P.3d at 630 (noting the party's constitutional right is violated when a
    seated juror is partial or unfair); Aftercare of Clark Cnty. v. Justice Court
    of Las Vegas Twp., 
    120 Nev. 1
    , 5, 
    82 P.3d 931
    , 933 (2004) (explaining
    Nevada's right to a jury trial in civil cases). Under Nevada law, when a
    failure to remove a biased juror results in an unfair empaneled jury, the
    error is reversible.   See Jitnan, 127 Nev. at , 254 P.3d at 630-31
    (holding that "a party's state constitutional rights [are not violated] unless
    he or she demonstrates actual prejudice; in other words, he or she must
    show that a member of the jury was unfair or partial"); 
    McNally, 85 Nev. at 700
    , 462 P.2d at 1018. This is true even if the error is harmless, as the
    biased juror's presence on the jury violates the parties' right to an
    impartial jury under the Nevada Constitution. See Preciado, 130 Nev. at
    , 318 P.3d at 179 (a court's error in failing to strike a biased juror is
    harmless if the juror is not ultimately empaneled); Aftercare of Clark

    (holding the presence of a biased juror on a jury panel in a Title VII

    venirepersons was harmless because they were not ultimately empaneled,
    130 Nev. at      , 254 P.3d at 630-31; 130 Nev. at        , 318 P.3d at 179, the
    biased juror was empaneled, and Sanders had no ability to exercise a
    peremptory strike to remove him from the jury. Under these particular
    facts, this court cannot state with certainty that Juror 9's preconceptions
    did not infect the jury panel or affect the jury's verdict in addition to
    biasing the juror's views. See Preciado, 130 Nev. at        , 318 P.3d at 179.
    A party's challenge for cause while an empaneled juror is present
    In conjunction with the district court's error in failing to strike
    Juror 9, we also consider the ramifications of the district court's conduct in
    asking the parties, in front of Juror 9, whether either wished to challenge
    Juror 9 for cause. On appeal, Sanders argues these actions constitute
    error. The parties did not object to the court's conduct at trial, and we
    generally do not review unpreserved issues on appeal.            See Old Aztec
    Mine, Inc. v. Brown,

    outside the presence of the prospective jurors during voir dire, see People
    v. Flockhart,    304 F'.3d 227, 236 n.8 (Colo. 2013) (discussing this
    jurisdictional split), several have noted this refusal may amount to error if
    it results in the seating of a prejudiced juror. 5 The American Bar
    Association recommends trial courts entertain challenges for cause outside
    the juror's presence, in part so the juror is not prejudiced against the party
    making the challenge. See ABA Standards for Criminal Justice: Discovery
    and Trial by Jury 15-2.7(a) (3d ed. 1996).
    After questioning Juror 9, and with Juror 9 still seated in the

    stated she wished to challenge Juror 9 for cause. The trial judge then
    asked Juror 9 to leave the courtroom.
    Although Nevada law does not mandate judges entertain
    challenges for cause outside of the prospective juror's presence, a critical
    difference exists between the challenge of a prospective juror during voir
    dire and a challenge for cause in front of an empaneled juror, particularly
    where the challenge occurs immediately after the empaneled juror admits
    facts establishing an inference of bias against the party making the
    challenge, as occurred here. Had this exchange occurred during voir dire,
    the trial judge's conduct may not have prejudiced Sanders, as she would
    have had the ability to use a peremptory strike if she feared Juror 9 would
    be biased by the failed challenge.
    Yet, "[w]hat may be innocuous conduct in some circumstances
    may constitute prejudicial conduct in a trial setting,"

    , 960 P.2d at 338 (quoting Parodi v. Washoe Med. Ctr., 
    111 Nev. 365
    ,
    367, 
    892 P.2d 588
    , 589 (1995)), and we hold such was the case under these
    facts. The district court's actions here placed Sanders in the difficult
    position of arguing before a juror that he should be removed, and that
    juror knew Sanders did not want him on the jury.             See Brooks v.
    Commonwealth,

    juror for cause due to the potential to create bias, especially when the
    challenge is argued in front of the juror). Under these facts, the district
    court's process of requiring the parties to issue their challenges for cause
    in front of Juror 9 amounted to plain error. See Gaxiola v. State, 
    121 Nev. 638
    , 654, 
    119 P.3d 1225

    Exhibit 62
    We next consider whether the district court erred by admitting
    exhibit 62 into evidence and allowing Dr. Duke to testify to that document.
    We will not overturn a district court's decision regarding the admission of
    evidence absent a palpable abuse of discretion, as district courts have
    broad discretion in determining whether to admit evidence.        Sheehan &
    Sheehan v. Nelson Malley & Co., 
    121 Nev. 481
    , 492, 
    117 P.3d 219
    , 226
    (2005). A district court abuses its discretion by admitting medical expert
    testimony that fails to comply with Nevada's rules governing the
    admission of evidence. See FCH1, LLC v. Rodriguez, 130 Nev.             ,
    
    335 P.3d 183
    , 190 (2014).
    We conclude the district court abused its discretion in
    admitting exhibit 62 because it was not properly authenticated. We
    likewise conclude the district court further abused its discretion in
    allowing Dr. Duke to testify to an undisclosed opinion regarding exhibit
    62. Finally, we conclude these errors were not harmless under these facts.
    Authentication
    Sanders argues exhibit 62 was improperly admitted because it
    was not authenticated. Sears-Page counters exhibit 62 was properly
    admitted because both parties had attempted to obtain it prior to trial, two
    hearsay exemptions applied, and this court should defer to the district
    court's decision. We disagree.
    COURT OF APPEALS

    Authentication is a basic prerequisite to the admission of
    evidence.   See NRS 52.015. Under NRS 52.015(1), authentication of a
    document requires evidence or some other showing "that the matter in
    question is what its proponent claims." Authentication relates to
    relevancy because "evidence cannot have a tendency to make the existence
    of a disputed fact more or less likely if the evidence is not that which its
    proponent claims." Rodriguez v. State, 128 Nev. „ 
    273 P.3d 845
    ,
    848 (2012) (internal quotation marks omitted).
    NRS 52.325 sets forth the procedure for authenticating
    medical records. This statute requires the custodian of the medical
    records to deliver a "true and exact" copy of the subpoenaed medical
    records to the clerk of the issuing court on or before the subpoena's
    deadline. NRS 52.325(1). The record "must be authenticated by an
    affidavit" in accordance with NRS 52.260(3), and signed by the custodian
    of the medical records, verifying the documents are accurate reproductions
    of the original medical records. NRS 52.325(2), (4). Additionally, the
    custodian must certify those original records were "made at or near the
    time of the act, event, condition, opinion or diagnosis by or from
    information transmitted by a person with knowledge in the course of a
    regularly conducted activity." NRS 52.325(2). Medical records delivered
    pursuant to a subpoena must "be kept in the custody of the clerk of the
    court issuing the subpoena, in a sealed container supplied by the
    custodian of the medical record." NRS 52.335(1).
    In addition, NRS 52.025 through NRS 52.105 provide a
    nonexhaustive list of methods by which a document may be authenticated.
    NRS 52.015(2). As relevant here, NRS 52.025 permits a witness to
    COURT OF APPEALS
    OF
    NEVADA
    20
    (0) 1947B
    authenticate a document through testimony "if the witness has personal
    knowledge that a matter is what it is claimed to be." (Emphasis added.)
    Where an expert authenticating a document has
    "[n]o. . . personal knowledge. . . as to how, when and in what manner" the
    document was made, the expert's testimony as to the document's
    authenticity, standing alone, is insufficient to authenticate the records.
    Frias v. Valle, 
    101 Nev. 219
    , 221-22, 
    698 P.2d 875
    , 877 (1985); see also
    NRS 52.025. In Frias, our supreme court considered an issue nearly
    identical to the one here. There, the district court allowed the admission
    of medical records after a doctor, who had treated the patient but who had
    not generated the records in question, testified the records belonged to the
    patient because they were labeled with the patient's name.       
    Frias, 101 Nev. at 221-22
    , 698 P.2d at 877. The doctor viewed the records for the
    first time while waiting to take the witness stand, and he therefore had no
    personal knowledge regarding those records. 
    Id. at 221,
    698 P.2d at 877.
    The Nevada Supreme Court reversed, holding the records were not
    properly authenticated because the specialist had no personal knowledge
    of the records' authenticity: he neither ordered the records nor used them
    in treating the patient, and he did not even view them until immediately
    prior to giving testimony. 
    Id. Analogous to
    Frias, the document here, exhibit 62, merely
    contained Sanders' name on it. Dr. Duke did not author the document,
    was not the custodian of the record, and testified the document looked like
    a typical medical record. Dr. Duke, therefore, was not a proper witness
    who could authenticate the document under NRS 52.025 and NRS 52.015.
    Because no other evidence corroborated exhibit 62, since Sanders testified
    she had not sought medical care for neck pain in 2005, and the exhibit was
    COURT OF APPEALS
    OF
    NEVADA
    21
    (0) 19475
    not properly authenticated, the district court abused its discretion in
    admitting exhibit 62.
    The district court admitted exhibit 62 over Sanders' objection,
    despite Sears-Page's failure to comply with any of NRS 52.325's
    requirements. Sears-Page's counsel admitted he did not know the identity
    or representative capacity of the person who literally "dropped off'
    documents to his paralegal that morning.      See NRS 52.325(1) (requiring
    the custodian of the records to deliver or mail the records). Here, the
    custodian of records did not deliver them to the clerk of the court as is
    required by NRS 52.325(1). See NRS 52.320(1) (defining "[c]ustodian of
    medical records"). And these medical records were not accompanied by a
    properly authenticated affidavit formatted according to NRS 52.260,
    signed by the custodian, or verified by the custodian to be "a true and
    complete reproduction of the original medical record." NRS 52.325(2).
    Nor was there any verification by the custodian that exhibit 62 was "made
    at or near the time of the. . . event" when it was purportedly recorded by
    Dr. Pollard or his staff during medical treatment of Sanders. 
    Id. The fact
                       that Sears-Page threatened to compel production of the medical records,
    and thereafter documents were dropped off during the trial, does not
    establish Dr. Pollard or his staff actually generated the documents or that
    the records were unaltered when the district court admitted exhibit 62
    into evidence. As in Frias, the district court committed error by admitting
    exhibit 62, and the error was not harmless.
    Undisclosed expert opinion
    Sanders next argues the district court compounded its error by
    allowing Dr. Duke, the retained defense expert, to thereafter testify to an
    undisclosed opinion regarding exhibit 62. Sears-Page claims the district
    COURT OF APPEALS
    OF
    NEVADA
    22
    (0) 1947B
    court did not err by admitting Dr. Duke's testimony regarding exhibit 62,
    which is particularly disconcerting because Sears-Page filed a motion in
    limine prior to trial to prohibit Sanders' experts from testifying to any
    undisclosed opinion. The district court granted Sears-Page's motion
    preventing Sanders' experts from offering any undisclosed opinions. Yet,
    the district court allowed Sears-Page's expert to testify to an undisclosed
    opinion on the final day of trial and after Sanders rested her case-in-chief.
    We agree this is error.
    Nevada Rule of Civil Procedure (NRCP) 16.1(a)(2) requires
    each party to provide a written disclosure of their experts and the contents
    of those experts' testimonies, including the information each expert
    considered in forming an opinion, well in advance of trial. Retained
    medical experts are subject to the requirements of this provision.         See
    FCH1, 130 Nev. at , 335 P.3d at 189 (holding that where a treating
    physician's testimony exceeds the scope of opinions "formed during the
    course of treatment" (internal quotation marks omitted), the physician
    "testifies as an expert and is subject to the relevant requirements"). This
    rule serves to place all parties on an even playing field and to prevent trial
    by ambush or unfair surprise. See 
    id. at ,
    335 P.3d at 190. The history
    behind the amendment of NRCP 16.1 reveals that one concern behind this
    rule was to prevent physicians from offering undisclosed opinions based
    upon evidence that had not been duly admitted or disclosed.          See In re
    Proposed Amendments to NRCP 16.1(a)(2), ADKT 472 (Exhibit A to Order
    Scheduling Public Hearing and Requesting Public Comment, November 9,

    In FCH1, the Nevada Supreme Court held a district court
    erred by allowing the plaintiffs treating doctors to offer opinions based, in
    part, on documents not disclosed during discovery. 130 Nev. at , 335
    P.3d at 190. One doctor read thousands of pages of records to form his
    opinion, yet disclosed only 21 pages during discovery, while other doctors'
    testimonies exceeded the bounds of their NRCP 16.1(a)(2)(B) disclosures
    and addressed topics not previously disclosed. 
    Id. at ,
    335 P.3d at 189-
    90. Ultimately, the district court abused its discretion in admitting this
    testimony. 
    Id. at ,
    335 P.3d at 190. Although the facts of FCH1 are
    somewhat different than the facts here, the supreme court's rationale is
    particularly instructive in this case as the court was ultimately concerned
    with basic fairness, while disfavoring trial by ambush. See 
    id. Sanders testified
    in her case-in-chief that she had not
    experienced neck pain nor had she received treatment for neck pain after
    2004 and prior to the accident. Dr. Duke, Sears-Page's retained medical
    expert, testified Sanders had a chronic condition causing her neck pain.
    Further, he opined Sanders' neck pain predated the accident, citing to a
    Nevada Spine Clinic intake form, which was created shortly before the
    accident, noting Sanders was experiencing neck pain during that time.
    After exhibit 62 was admitted into evidence, the district court allowed Dr.
    Duke to make additional opinions based on its contents supporting his
    previous opinion that Sanders experienced chronic neck pain for years
    prior to the accident and that the accident did not contribute to her pain.
    The district court's decision allowing Dr. Duke to make an
    undisclosed opinion that exhibit 62 supported his position that Sanders
    COURT OF APPEALS
    OF
    NEVADA

    (0) 19475
    experienced chronic neck pain for years prior to the accident directly
    violated NRCP 16.1.
    Although NRCP 16.1(a)(2)(B) allows the trial court to relieve a
    party of its duty to comply with the written report requirement for good
    cause, no facts support the district court's decision that good cause existed
    in this case. Moseley v. Eighth Judicial Dist. Court, 
    124 Nev. 654
    , 668
    n.66, 
    188 P.3d 1136
    , 1146 n.66 (2008) (providing "[g] ood cause generally is
    established when it is shown that the circumstances causing the failure to
    act are beyond the individual's control"). Here, Sears-Page had ample
    opportunity to obtain complete medical records from Dr. Pollard's office
    prior to trial and failed to do so. Rather, she proceeded to trial and
    defended with documents and testimony previously obtained and disclosed
    during discovery. Sears-Page's actions threatening Dr. Pollard with
    contempt and obtaining records during trial do not constitute good cause,
    as nothing prevented Sears-Page from taking such actions prior to the
    discovery deadline.
    Moreover, although this is not a traditional trial-by-ambush
    situation because Sears-Page did not intentionally withhold information,
    the trial court's admission of exhibit 62 and allowing Dr. Duke to testify
    regarding its contents nevertheless unfairly surprised Sanders and
    damaged her case. CI Sheehan & 
    Sheehan, 121 Nev. at 485
    , 
    492-93, 117 P.3d at 222
    , 226-27 (noting that though a party intentionally withheld
    information, it was not a trial-by-ambush situation because that
    information was later disclosed). The district court not only violated the
    25
    express requirements of Rule 16.1, but also its purpose and policy. 6 See
    FCH1, 130 Nev. at , 335 P.3d at 190 (noting the purpose of NRCP
    16.1's document disclosure requirements). Accordingly, under these facts,
    the district court erred in allowing Dr. Duke to testify to an undisclosed
    expert opinion.
    Harmless error
    Sears-Page argues any error regarding exhibit 62 is harmless
    because Dr. Duke formed his opinion on other evidence previously
    disclosed to Sanders. We disagree.
    Although we do not reverse a decision where error is harmless,
    "if the moving party shows that the error is prejudicial, reversal may be
    appropriate."     Wyeth v. Rowatt,   
    126 Nev. 446
    , 465, 
    244 P.3d 765
    , 778
    (2010). An error is prejudicial where the moving party shows "that the
    error affects the party's substantial rights so that, but for the alleged
    error, a different result might reasonably have been reached. The inquiry
    is fact-dependent and requires us to evaluate the error in light of the
    entire record."

    The district court's errors in admitting exhibit 62, although
    the document was not properly authenticated, and in allowing Dr. Duke to
    testify as to an undisclosed opinion regarding that document, were not
    harmless in light of the record as a whole. Importantly, Dr. Duke's

    Procedure 26, which was enacted to prevent ambush at trial. See Ortiz-

    pretrial disclosures focused on records noting Sanders' history of pain in
    her legs and back, yet Dr. Duke utilized exhibit 62 at trial to specifically
    recognize Sanders had an ongoing recorded history of chronic neck pain.
    And, exhibit 62 substantiated Dr. Duke's trial opinion of Sanders' ongoing
    history of neck pain, which significantly bolstered Sears-Page's defense
    while simultaneously impeaching the credibility of Sanders' testimony
    that she had not sought treatment for neck pain after 2004 and before the
    accident.
    This created both unfair surprise to Sanders and prejudice to
    her case. Sanders was unaware of exhibit 62 or Dr. Duke's opinion as to
    that document until the final hours of the trial. And, as exhibit 62 and Dr.
    Duke's opinion regarding that document significantly helped Sears-Page's
    defense and damaged the credibility of Sanders' testimony regarding the
    onset of her pain, but for this document and Dr. Duke's undisclosed
    opinion, the jury may have reached a different result. The unfair surprise
    under these facts is further apparent considering the district court allowed
    Dr. Duke's undisclosed opinion despite granting Sears-Page's pretrial
    motion preventing Sanders' experts from presenting undisclosed opinions.
    Because the district court allowed Dr. Duke, a retained
    defense expert, to testify to an undisclosed opinion after Sanders rested
    her case-in-chief, and because the district court previously granted Sears-
    Page's motion preventing Sanders' experts from presenting undisclosed
    opinions, the district court abused its discretion. And, because these
    errors resulted in prejudice to Sanders' case, the error was palpable and is
    reversible.   See 
    Wyeth, 126 Nev. at 465
    , 244 P.3d at 778 (holding such
    error is reversible where the result may have been different but for the
    error).

    CONCLUSION
    The district court erred in failing to strike Juror 9 for cause as
    Juror 9's statements in their totality evinced bias against Sanders' case.
    This error resulted in an unfair empaneled jury, requiring reversal. The
    district court's process in allowing Juror 9 to be present while Sanders'
    challenged Juror 9 for cause likewise constitutes plain error under these
    facts. Further, the district court erred by admitting into evidence exhibit
    62 over Sanders' objection as this document was not properly
    authenticated. Finally, the district court erred when it allowed a retained
    defense expert to testify to an undisclosed opinion by utilizing exhibit 62.
    Accordingly, we reverse and remand for a new trial.
