    CHRISTENSEN, Justice.
    This medical malpractice case concerns plaintiff’s suit against
    defendants for negligent acts or omissions during plaintiff’s birth.
    Defendants encountered the medical emergency of shoulder dystocia after
    plaintiff’s shoulder became stuck on his mother’s pelvis.       Defendants
    performed maneuvers to resolve the stuck shoulder, but plaintiff was born
    with a permanent injury to his left arm preventing normal use and
    function.     The jury returned a defense verdict and the district court
    dismissed plaintiff’s claims. On direct appeal, we first consider whether
    the district court committed reversible error in the specifications of
    negligence it submitted to the jury. We also consider whether the district
    court abused its discretion when it prohibited plaintiff from offering
    evidence of defendants’ continuing medical education credits. Next, we
    are asked to determine whether the district court properly admitted expert
    opinion testimony. Lastly, we determine whether limiting the jury’s access
    to evidence during deliberations was within the district court’s discretion.
    For reasons expressed below, we conclude the plaintiff’s proffered
    instructions were sufficiently encompassed by the instructions submitted
    or, in the alternative, were not supported by substantial evidence. We
    further conclude the district court did not abuse its discretion in
    prohibiting the plaintiff from introducing continuing medical education
    records to show a breach in the standard of care. However, although it
    was an abuse of discretion for the district court to prohibit the use of
    continuing medical education records as impeachment evidence, the error
    was harmless. Next, we determine defendants’ expert opinion testimony
    was properly disclosed and did not reflect an opinion in anticipation of
    litigation.   We further determine the district court did not abuse its
    4
    discretion in limiting the jury’s access to video evidence during
    deliberation; it was a judgment call for the district court to make.
    I. Background Facts and Proceedings.
    T.D. was born on August 31, 2007, at the Henry County Health
    Center (HCHC).         Dr. Widmer, employed by Family Medicine of Mt.
    Pleasant, P.C., 1 was the physician in charge of T.D.’s prenatal care and
    delivery. Many of the facts surrounding T.D.’s birth are not disputed.
    During the delivery, T.D.’s head delivered but his left shoulder became
    stuck on his mother’s pelvis. This situation, a shoulder dystocia, is a
    medical emergency because the infant’s delay in birth may cause severe
    brain damage or death if not resolved in six minutes or less. Dr. Widmer
    and the nurses performed maneuvers that resolved the shoulder dystocia
    in one minute and ten seconds. However, T.D. was born with a permanent
    injury to his left brachial plexus preventing normal use and function of his
    arm. T.D.’s delivery was captured on a twenty-one minute birth video
    recorded by T.D.’s aunt.
    T.D., through a conservator, 2 filed a medical malpractice action on
    March 10, 2016, in Henry County alleging defendants were negligent
    during labor and delivery, causing injury. Nearly a year and a half later,
    T.D. filed a motion for leave to amend and substitute his original petition.
    Defendants resisted, citing concerns that T.D. was raising new claims of
    negligent training and credentialing for the first time less than sixty days
    before trial. On October 13, 2017, after an evidentiary hearing, the district
    1We will refer to HCHC, Dr. Widmer, and Family Medicine of Mt. Pleasant, P.C.
    jointly as “defendants.”
    2T.D.’s mother, Lisa Hirschy, individually and as next friend of T.D., filed the
    original petition against the defendants. The original petition was later amended and
    substituted Hirschy with plaintiff “Larry Eisenhauer, Conservator, ex. rel.
    Conservatorship of [T.D.]” We will refer to the plaintiff simply as T.D.
    5
    court determined T.D.’s proposed amendment “that adds a new claim of
    negligent training does ‘substantially change the issues or defenses of the
    case.’ Allowing the amendment would prejudice the defense in this case.”
    It ruled,
    The primary issues in this case remain as to what the
    applicable standard of care was on the date in question and
    whether there was a violation of this standard with a causal
    relationship to the injury.
    ....
    To the extent there may be any reference in the
    [a]mended [p]etition that relates to a theory of recovery based
    on negligent training or credentialing, the amendment is
    denied.
    The district court later granted defendants’ motion in limine relating to,
    among other things, any reference to either HCHC’s training and
    credentialing process or Dr. Widmer’s training as a family practice
    physician, including his Continuing Medical Education (CME) records.
    Trial commenced on November 7, 2017, and concluded on November
    17.   Both parties offered expert testimony to support their respective
    positions. T.D. offered the birth video into evidence without objection. At
    the close of his case-in-chief, T.D. sought to admit Dr. Widmer’s CME
    records and made on offer of proof. The district court affirmed its prior
    ruling and prohibited T.D. from offering evidence of the CME records.
    During direct examination by defendants, Dr. Widmer testified:
    Q. Do you have an opinion as to whether the
    maneuvers you used were in conformity with the standard of
    care?
    MR. GOODMAN: Undisclosed opinion.
    THE COURT: Overruled.
    A. I believe I did.
    6
    On the sixth day of trial, during redirect examination, Dr. Widmer
    referred to a single page of handwritten notes. He testified to creating the
    notes when he reviewed the birth video and stated his notes would assist
    in recalling the times he heard fetal heart rates without the need to watch
    the entire birth video.   Defendants later moved to admit the notes as
    demonstrative evidence.
    During deliberations, the jury asked to view the birth video, which
    was not submitted to the jury for deliberations. The district court complied
    with the request and played the video for the jury once in its entirety. Over
    plaintiff’s objections, the birth video was not sent back to the jury room
    during deliberations but could be viewed an additional time upon request
    by the jury. Such a request was made and the video was again played in
    its entirety.   Subsequently, the jury returned a verdict for defendants,
    finding   neither   HCHC’s    nurses       nor   Dr. Widmer   were   negligent.
    Consequently, the jury did not reach the question of causation or
    damages.
    The district court, based upon the jury’s verdict, entered an order
    dismissing T.D.’s claims. T.D. appealed the district court order, and we
    retained the appeal.
    II. Standard of Review.
    The standard of review for jury instructions is for prejudicial error
    by the district court. Thavenet v. Davis, 
    589 N.W.2d 233
    , 236 (Iowa 1999)
    (en banc). Therefore, a district court’s refusal to give a requested jury
    instruction is reviewed for correction of errors at law. See Alcala v. Marriott
    Int’l, Inc., 
    880 N.W.2d 699
    , 707 (Iowa 2016).          “Instructions must be
    considered as a whole, and if the jury has not been misled there is no
    reversible error.” 
    Thavenet, 589 N.W.2d at 236
    . “In considering whether
    the instruction is supported by substantial evidence, we give the evidence
    7
    the most favorable construction it will bear in favor of supporting the
    instruction.” Asher v. OB–Gyn Specialists, P.C., 
    846 N.W.2d 492
    , 496–97
    (Iowa 2014), overruled by 
    Alcala, 880 N.W.2d at 707
    –08, 708 n.3.
    A district court’s decision to admit relevant evidence is reviewed for
    an abuse of discretion. See Mohammed v. Otoadese, 
    738 N.W.2d 628
    , 631
    (Iowa 2007). “An abuse of discretion occurs when ‘the court exercise[s]
    [its] discretion on grounds or for reasons clearly untenable or to an extent
    clearly unreasonable.’ ” Graber v. City of Ankeny, 
    616 N.W.2d 633
    , 638
    (Iowa 2000) (en banc) (alteration in original) (quoting Waits v. United Fire
    & Cas. Co., 
    572 N.W.2d 565
    , 569 (Iowa 1997)). Grounds or reasons are
    clearly untenable if they are not supported by substantial evidence or if
    they are based on an erroneous application of law. 
    Id. “A party
    may claim
    error in a ruling to admit or exclude evidence only if the error affects a
    substantial right of the party . . . .” Iowa R. Evid. 5.103(a).
    We review whether a district court properly admitted expert
    testimony for abuse of discretion. See Hansen v. Cent. Iowa Hosp. Corp.,
    
    686 N.W.2d 476
    , 479 (Iowa 2004).
    Similarly, “[s]ubmission of exhibits to the jury is a matter resting in
    [the] trial court’s discretion.” Brooks v. Holtz, 
    661 N.W.2d 526
    , 532 (Iowa
    2003) (alteration in original) (quoting Heth v. Iowa City, 
    206 N.W.2d 299
    ,
    303 (Iowa 1973)).
    III. Analysis.
    A. Specifications of Negligence. We first consider whether there
    was reversible error in the district court’s specifications of negligence. In
    a medical malpractice action, “a plaintiff must produce evidence that (1)
    establishes the applicable standard of care, (2) demonstrates a violation of
    this standard, and (3) develops a causal relationship between the violation
    and the injury sustained.” Oswald v. LeGrand, 
    453 N.W.2d 634
    , 635 (Iowa
    8
    1990). The questions respecting the violation of a standard of care and
    the causal relationship are ordinarily for the trier of fact. See Speed v.
    State, 
    240 N.W.2d 901
    , 904 (Iowa 1976).
    A plaintiff is required to identify the specific acts or omissions relied
    upon to generate questions for the trier of fact. See Herbst v. State, 
    616 N.W.2d 582
    , 585 (2000) (en banc).         As we explained in Herbst, “Jury
    instructions should be formulated so as to require the jury to focus on
    each specification of negligence that finds support in the evidence.” 
    Id. (quoting Bigalk
    v. Bigalk, 
    540 N.W.2d 247
    , 249 (Iowa 1995)). Put another
    way, a party is entitled to have its legal theory submitted to the jury if that
    theory is supported by substantial evidence. See Ludman v. Davenport
    Assumption High Sch., 
    895 N.W.2d 902
    , 919–20 (Iowa 2017).
    Of course, whether a jury instruction sufficiently encompasses each
    specification of negligence alleged by a plaintiff is determined by the facts
    of the particular case. See 
    Herbst, 616 N.W.2d at 586
    . Iowa law requires
    a court give a requested instruction as long as the instruction is a correct
    statement of law, is applicable to the case, and is not otherwise embodied
    elsewhere in the instructions. See 
    Ludman, 895 N.W.2d at 919
    ; Porter v.
    Iowa Power & Light Co., 
    217 N.W.2d 221
    , 234 (Iowa 1974). This principle,
    however, does not require a court give instructions that provide undue
    emphasis to any particular aspect of the case, Burkhalter v. Burkhalter,
    
    841 N.W.2d 93
    , 106 (Iowa 2013), or that duplicate specifications
    adequately encompassed elsewhere in the instructions, 
    Porter, 217 N.W.2d at 233
    –34.
    T.D. challenges the manner in which the district court instructed
    the jury on his specific claims of negligence. Regarding Dr. Widmer, T.D.
    proposed the following instruction with six subparts:
    9
    Dr. Widmer was negligent by failing to meet the standard of
    care in the following way:
    a. Repeatedly directing [mother] to push after shoulder
    dystocia was identified and traction failed to deliver
    the stuck shoulder;
    or
    b. Applying improper traction to [T.D.]’s head or neck
    during the delivery;
    or
    c. Failing to properly and effectively supervise, direct,
    or coordinate the efforts of the delivery team;
    or
    d. Mistakenly concluding that [T.D.] was experiencing
    bradycardia and as a result, delivering [T.D.] hastily
    and without due care;
    or
    e. Failing to follow the HCHC policy on Shoulder
    Dystocia, or Vacuum Extraction, or Pitocin;
    or
    f. Failing to properly and effectively use maternal and
    fetal maneuvers to safely deliver [T.D.] after shoulder
    dystocia occurred, including, but not limited to:
    McRoberts maneuver, suprapubic pressure, Wood’s
    screw, reverse Wood[’s] screw (Rubin’s), delivering
    the posterior arm, and Gaskin’s maneuver;
    The district court whittled down T.D.’s proposed specifications about
    Dr. Widmer and instructed the jury on the following specifications of
    negligence:
    Dr. Widmer was negligent by failing to meet the standard of
    care in one or more of the following ways:
    (a) in failing to direct or coordinate proper maneuvers
    to deliver the baby after the recognition of shoulder
    dystocia;
    10
    (b) by applying excessive or improper traction in an
    effort to deliver him after the recognition of shoulder
    dystocia;
    Regarding the nurses, T.D. proposed the following instruction with
    five subparts:
    Either nurse or both Rebecca Fraise, R.N. and Yvonne
    Sloan, R.N. were negligent by failing to meet the standard
    of care in the following way:
    a. Repeatedly directing [mother] to push after shoulder
    dystocia was identified and traction failed to deliver
    the stuck shoulder;
    or
    b. Failing to follow the HCHC policy on Shoulder
    Dystocia or Pitocin;
    or
    c. Failing to properly and effectively perform the
    McRoberts maneuver and suprapubic pressure, to
    safely deliver [T.D.] after shoulder dystocia
    occurred[;]
    or
    d. Acting without due care in delivering [T.D.];
    or
    e. Failing to call for help;
    The district court whittled down T.D.’s proposed specifications about the
    nurses and instructed the jury on the following specifications of
    negligence:
    That either of the nurses was negligent by failing to meet the
    standard of care in the following way:
    (a) in the performance of the McRobert[s] maneuver
    and/or the application of suprapubic pressure.
    T.D. asserts the districts court’s instructions failed to instruct the
    jury on certain acts or omissions in which defendants violated the
    11
    standard of care.    Specifically, T.D. claims the district court failed to
    incorporate the following specifications of negligence against Dr. Widmer:
    (1) directing to push after shoulder dystocia was identified, (2) failing to
    properly and effectively direct the delivery team as well as failing to
    properly and effectively use maternal and fetal maneuvers, and
    (3) mistakenly concluding T.D. was experiencing bradycardia.            With
    respect to the HCHC nurses, T.D. claims the district court failed to
    incorporate two specifications of negligence: (1) directing to push after
    shoulder dystocia was identified, and (2) failing to properly and effectively
    perform maternal maneuvers.
    Defendants argue that T.D.’s proffered specifications of negligence
    were adequately embodied in the court’s final jury instructions, and
    because the more general language allowed T.D. to emphasize his proffered
    specifications of negligence throughout his trial presentation, the district
    court’s refusal to provide instructions on specific acts or omissions was
    not prejudicial.
    T.D.’s proposed instructions indicated Dr. Widmer and the HCHC
    nurses failed to meet the standard of care by “[r]epeatedly directing
    [mother] to push after shoulder dystocia was identified and traction failed
    to deliver the stuck shoulder.” This theory found support in the testimony
    of each party’s expert, which revealed all commands to push and tractional
    efforts should cease when shoulder dystocia is first recognized.         The
    experts also agreed maternal maneuvers, such as the McRoberts
    maneuver, 3 should be executed to relieve shoulder dystocia. Once the
    McRoberts maneuver is implemented, pushing and tractional forces are
    allowed to resume. Arguably, a breach of the standard of care could occur
    3The   McRoberts maneuver is a nurse performed maneuver that raises the
    mother’s legs to her chest in order to resolve shoulder dystocia.
    12
    if commands to push and tractional efforts occurred after dystocia was
    recognized but before the McRoberts maneuver was implemented.
    We think the specific act or omission of repeatedly directing to push
    was adequately encompassed in the district court’s instructions.         The
    district court’s specifications stated Dr. Widmer was negligent by “failing
    to direct or coordinate proper maneuvers” and “applying excessive or
    improper traction . . . after the recognition of shoulder dystocia.” These
    instructions are directly related to the concept of “directing to push.” The
    record indicates it was Dr. Widmer’s responsibility to communicate with
    the delivery team and it was his responsibility to coordinate maternal
    maneuvers. Any direction by Dr. Widmer to push after shoulder dystocia
    was recognized but before the McRoberts maneuver was implemented falls
    squarely within his failure to direct or coordinate the proper maneuver and
    could result in improper traction.       The district court’s instructions
    adequately instructed the jury on each alleged act or omission.
    The same is also true for the HCHC nurses. Failing to meet the
    standard of care “in the performance of the McRobert[s] maneuver”
    encompassed “directing to push” after the recognition of shoulder dystocia.
    Indeed, HCHC nurses could fail to meet the standard of care if they
    directed the mother to push after the recognition of shoulder dystocia but
    before implementation of the McRoberts maneuver—a direction that is
    contrary to the performance of the maneuver as established in the record.
    Moreover, the district court illustrated the difficulty that a separate
    instruction on “directing to push” would create in conjunction with an
    instruction regarding the proper maneuver to deliver T.D.
    I mean, you can’t say stop pushing and just sit there the rest
    of the day. At some point you have to start pushing again. I
    think that was the testimony of all the experts. I mean, you
    can’t just stop and lollygag around. At some point somebody
    has to push again.
    13
    We agree with its reasoning. Directions to intermittently start and
    stop pushing at certain points in the delivery process are part of the proper
    maneuver.    This is supported by the testimony of each party’s expert.
    Therefore, the district court’s jury instructions adequately encompassed
    T.D.’s specifications of negligence. See 
    Porter, 217 N.W.2d at 233
    .
    T.D.’s proposed instructions also drew a distinction between
    maternal and fetal maneuvers. It was T.D.’s theory that HCHC nurses
    failed to properly and effectively perform the maternal maneuver
    (McRoberts maneuver and suprapubic pressure 4), that Dr. Widmer failed
    to properly and effectively supervise the delivery team,              and that
    Dr. Widmer failed to properly and effectively use fetal maneuvers. When
    faced with an improper and ineffective maternal maneuver, T.D.’s expert
    indicated it was Dr. Widmer’s responsibility to direct the proper and
    effective performance of the maternal maneuver. If the proper and effective
    maternal maneuver failed to release the shoulder dystocia, then
    Dr. Widmer should have moved on to other fetal maneuvers (physician-
    applied maneuvers).
    We    conclude     the    district    court’s   instructions   adequately
    encompassed T.D.’s legal theories of negligence. To begin, both parties’
    experts agreed maternal maneuvers are performed by nurses. Even T.D.
    concedes “the HCHC nurses attempted the proper maternal maneuvers—
    McRobert[s] and suprapubic pressure.”           Yet, T.D. asserts the district
    court’s exclusion of “proper and effective” conveyed only a specification of
    whether the HCHC nurses conducted the proper maneuver, not whether
    it was effective. This exclusion, we believe, was fully encompassed in the
    instruction submitted.         The district court’s instruction begins by
    4Suprapubic   pressure is a nurse applied maneuver that pushes down on the
    mother’s pubic bone to resolve shoulder dystocia.
    14
    explaining that HCHC nurses are negligent if they fail to meet the standard
    of care during the performance or application of a maternal maneuver. We
    are convinced a negligent performance or application of a maternal
    maneuver sufficiently encompassed an act that would violate the standard
    of care, i.e, inadequate or ineffective. The district court “need not adopt
    the form requested by a party.” Schuller v. Hy-Vee Food Stores, Inc., 
    328 N.W.2d 328
    , 332 (Iowa 1982).
    A similar analysis is appropriate for Dr. Widmer’s specifications.
    T.D.’s proposed instructions sought to distinguish two different acts or
    omissions: (1) Dr. Widmer’s failure to supervise maternal maneuvers and
    (2) Dr. Widmer’s failure to use fetal maneuvers. We conclude the district
    court’s instruction sufficiently highlighted two distinct acts or omissions.
    First, unlike the court’s instruction for the HCHC nurses’ specification,
    Dr. Widmer’s instruction was not narrowed to the maternal maneuvers
    (McRoberts and suprapubic pressure). Quite the opposite. It set forth his
    duty to “direct or coordinate proper maneuvers.” We read this two-fold
    specification to include multiple maneuvers, if necessary.
    Second, the district court’s specification reflected the sequential
    nature of proper maneuvers, as expressed by the parties’ expert testimony.
    If shoulder dystocia is encountered during the delivery, it is the physician’s
    responsibility to direct the proper maternal maneuver.         If the proper
    maternal maneuver does not resolve the shoulder dystocia, the physician
    should coordinate a number of fetal maneuvers.          The record indicates
    maternal maneuvers are nurse applied, in contrast to fetal maneuvers,
    which are physician applied. T.D. presented significant evidence reviewing
    fetal maneuvers and their proper use.
    T.D. argues the district court’s use of “direct or coordinate” limited
    Dr. Widmer’s    liability   to   maternal   maneuvers   because   “direct   or
    15
    coordinate” each refer to controlling or managing others.     However, read
    in the context of the two-fold specification, we disagree.      Dr. Widmer’s
    negligence may have stemmed from his failure to direct maternal
    maneuvers or from his failure to coordinate fetal maneuvers. Compare
    Direct, Webster’s Third New International Dictionary (unabr. 2002) (“[T]o
    dedicate to a person[,] . . . to dispatch, aim, or guide usu. along a fixed
    path”), with Coordinate, Webster’s Third New International Dictionary (“[T]o
    bring into a common action, movement, or condition : regulate and
    combine in a harmonious action”). With respect to the district court’s
    exclusion of “effective,” we are again convinced the standard of care implies
    effective direction or coordination.
    Whether Dr. Widmer was negligent for his failure to direct or
    coordinate proper maneuvers was a question for the jury. We believe the
    district court’s instruction sufficiently advised the jury of specific acts or
    omissions related to maternal and fetal maneuvers.
    T.D. also argues that the district court erred in its refusal to provide
    T.D.’s specification of negligence regarding Dr. Widmer’s assessment of
    bradycardia:
    (d) Mistakenly concluding that [T.D.] was experiencing
    bradycardia and as a result, delivering [T.D.] hastily and
    without due care;
    The record indicates bradycardia occurs when the fetal heart rate remains
    below 110 beats per minute for a full ten-minute period.               When
    bradycardia occurs, there is a danger the fetus will be deprived of oxygen
    and suffer a brain injury. A more severe bradycardia will result in less
    time for a physician to complete delivery.
    Defendants argue the evidence is insufficient to support T.D.’s
    specification of negligence. If substantial evidence in the record supports
    16
    T.D.’s legal theory concerning bradycardia, he is entitled to submit that
    theory to the jury. See 
    Lundman, 895 N.W.2d at 919
    –20. “Evidence is
    substantial enough to support a requested instruction when a reasonable
    mind would accept it as adequate to reach a conclusion.”

    (quoting Beyer v. Todd, 
    601 N.W.2d 35
    , 38 (Iowa 1999)). “[W]e give the
    evidence the most favorable construction it will bear in favor of supporting
    the instruction.” 
    Asher, 846 N.W.2d at 496
    –97.
    Applying this favorable construction, we determine a reasonable
    mind would not accept the evidence as adequate to conclude there was no
    bradycardia. Dr. Widmer testified T.D.’s heart rate lowered to eighty beats
    per minute, which revealed T.D. “was having some distress.”              In
    Dr. Widmer’s opinion, T.D. was experiencing late deceleration following his
    mother’s push and contraction, and “[t]hat’s usually a sign that the baby
    is not doing well.” In T.D.’s circumstances, the late deceleration kept his
    heart rate down in the eighty beats-per-minute range. Further, T.D.’s own
    expert testified it was impossible to determine whether Dr. Widmer
    misdiagnosed bradycardia because the fetal heart rate charts only
    reflected T.D.’s heart rate every five minutes. He stated,
    [W]e really don’t know what the care showed, other than
    nursing charts that every five minutes heart rate 80’s to 90’s,
    90 to a hundred, but it doesn’t tell you what it is minute to
    minute to minute, so we don’t know if these are what we call
    variable decelerations . . . . So it may have been indicated, it
    may not have been. I don’t think there’s enough information
    there in the record to tell you.
    (Emphasis added.) The record contains insufficient evidence to support
    the legal theory that Dr. Widmer mistakenly concluded T.D. was
    experiencing bradycardia. We conclude the district court did not err in
    refusing T.D.’s specification of negligence.
    17
    T.D. next contends Iowa caselaw is clear on the specification issue:
    jury instructions must include each specification of negligence that finds
    support in the evidence. Caselaw in the form of premises liability provides
    relevant rules of proper jury instructions.
    “The court is entitled to choose its own language in submitting an
    issue and need not adopt the form requested by a party.” 
    Schuller, 328 N.W.2d at 332
    . That was the rule expressed by our court in Schuller after
    we determined the jury instructions adequately incorporated plaintiff’s
    specifications of negligence. See 
    id. There, Schuller
    was injured after
    tripping over an ashtray canister as he entered the aisle in defendant’s
    grocery store.   
    Id. at 330.
      He sought four specifications of negligence
    against the grocery store: “blocking an aisle by placing an ashtray where
    a customer was expected to walk, placing an ashtray in a concealed
    location, failing to place the ashtray in a safe location, and failing to warn
    of the ashtray’s location.” 
    Id. at 331–32.
    The district court only submitted instructions concerning whether
    the grocery store was negligent “in placing the ashtray stand in an aisle
    where customers were expected to walk” and circumstances that would
    give rise to a duty to warn. 
    Id. at 332.
    We concluded Schuller’s first three
    specifications of negligence related to the concept of ashtray placement,
    which was adequately incorporated in the single specification submitted.
    See 
    id. In Bigalk,
    our court addressed the issue of whether a plaintiff was
    entitled to have the jury instructed on each alleged act or 
    omission. 540 N.W.2d at 248
    . After falling into an unguarded stairwell, Bigalk brought
    a personal injury claim against the property owner. 
    Id. Her theory
    was,
    as a possessor of land, the property owner owed a duty under Restatement
    (Second) of Torts. 
    Id. 18 Bigalk
    claimed the property owner was negligent in failing to warn
    of the danger, failing to provide adequate lighting, failing to cover the open
    stairwell, and failing to provide a railing around the stairwell. 
    Id. at 248–
    49.   The district court limited the specifications of negligence and
    instructed the jury, “The Defendant was negligent in failing to make the
    condition (open stairway) safe or in failing to warn the Plaintiff of the
    condition and risk involved.” 
    Id. at 249.
    Bigalk objected on the ground
    that, apart from the warning language, the instructions did not advise the
    jury concerning the specific acts or omissions she claims were negligent
    conduct. 
    Id. at 249.
    On appeal, we reversed the district court. 
    Id. at 250.
    We said, “[Bigalk] was entitled to have the jury instructed in the present
    case concerning each alleged act or omission that found support in the
    evidence.” 
    Id. We later
    contrasted Schuller with Bigalk in Herbst, 
    616 N.W.2d 582
    .
    The narrow question in Herbst was whether the district court adequately
    instructed the jury concerning specifications of negligence. 
    Id. at 585.
    We
    identified two issues with the instructions given in Herbst. 
    Id. at 587.
    First, the district court did not adequately instruct the jury concerning
    defendant’s negligent act.    
    Id. Second, the
    jury was not adequately
    instructed concerning Herbst’s theory of defendant’s negligent omission.
    
    Id. Herbst sustained
    injuries while descending from a stage in a
    university rehearsal hall. 
    Id. at 583.
    It was her theory that the university
    was negligent by (1) “permitting makeshift stairs to be used,” (2) “failing to
    provide a safe and secure set of stairs,” and (3) “failing to provide
    unimpeded access to the permanent stairs.” 
    Id. at 586.
    The district court
    instructed the specification of negligence as “failing to provide safe and
    secure access onto the stage.” 
    Id. at 586–87.
                                         19
    We concluded the instruction did not adequately instruct the jury
    concerning each alleged act (permitting makeshift stairs to be used) or
    omission (failing to provide safe and secure access). See 
    id. at 587.
    We
    determined Herbst’s third specification of negligence (failing to provide
    unimpeded access) was to be encompassed in the first two instructions.
    See 
    id. Upon our
    review, we determine the jury was adequately instructed
    concerning T.D.’s specifications of negligence.     Viewed as a whole, the
    district court’s instructions ensured the jury would give consideration to
    each alleged act or omission. In Bigalk and Herbst, the standard of care
    was simply repeated to the jury.          Like Schuller, the district court’s
    instructions in this case related to the concept of specific acts or omissions
    during the delivery of T.D. and sufficiently encompassed T.D.’s
    specifications of negligence.
    We need not reach T.D.’s claim of prejudice given our holding on the
    manner in which the district court instructed the jury. “An error in giving
    an instruction ‘does not warrant reversal unless the error is prejudicial to
    a party.’ ” 
    Asher, 846 N.W.2d at 496
    (quoting 
    Herbst, 616 N.W.2d at 585
    ).
    “Prejudice results when the trial court’s instruction materially misstates
    the law, confuses or misleads the jury, or is unduly emphasized.”
    Anderson v. Webster City Cmty. Sch. Dist., 
    620 N.W.2d 263
    , 268 (Iowa
    2000) (en banc).    In any event, T.D. was free to emphasize, and did
    emphasize, that his proffered specifications of negligence breached the
    standard of care. By his own admissions, T.D. indicated he emphasized
    his specifications of negligence throughout his opening, case-in-chief, and
    closing. While discussing the proffered instructions with the parties, the
    district court even encouraged T.D. to argue his specifications: “You can
    argue that point, that’s fine. You can argue that all you want, and that’s
    20
    fine . . . .” T.D.’s presentation of his legal theory, in conjunction with the
    instructions as a whole, properly explained the relevant law to the jury.
    See 
    id. (“In this
    case, all the instructions when read together properly
    explained the applicable law to the jury.”). We conclude the district court
    fulfilled its “duty to see that a jury has a clear and intelligent
    understanding of what it is to decide.” Sonnek v. Warren, 
    522 N.W.2d 45
    ,
    47 (Iowa 1994).
    B. Training and Medical Education. The district court prohibited
    T.D. from offering evidence of Dr. Widmer’s CME records. T.D. contends,
    as he did in the district court, that Dr. Widmer’s training and medical
    education records were admissible.          The CMEs were admissible, T.D.
    argues, because (1) the records were relevant to show a breach in the
    standard of care and (2) he was entitled to introduce impeachment
    evidence that lessened the weight of Dr. Widmer’s expert opinion.            We
    disagree with T.D.’s contention regarding the relevancy of CME records to
    show a breach in the standard of care, but we agree that he was entitled
    to introduce CME records for impeachment purposes. However, we affirm
    the district court’s decision because the erroneous ruling did not affect
    T.D.’s substantial rights. See Iowa R. Evid. 5.103(a).
    The procedural background surrounding Dr. Widmer’s CME records
    offers insight to the district court’s ruling. A year and a half after T.D. filed
    his petition in district court, he filed a motion for leave to amend and
    substitute the original petition. Defendants resisted, citing concerns that
    T.D. was raising new claims of negligent training and credentialing for the
    first time less than sixty days before trial. The district court denied T.D.’s
    motion. The order stated, “It is clear that what the [p]laintiff is asking for
    is the inclusion of a claim of negligent training.” It concluded the proposed
    amendment, which added a new claim of negligent training, would
    21
    substantially change the issues or defenses of the case. The district court
    ruled:
    The primary issues in this case remain as to what the
    applicable standard of care was on the date in question and
    whether there was a violation of this standard with a causal
    relationship to the injury.
    ....
    To the extent there may be any reference in the
    [a]mended [p]etition that relates to a theory of recovery based
    on negligent training or credentialing, the amendment is
    denied.
    The district court later granted defendants’ joint motion in limine
    regarding any reference to HCHC’s training and credentialing process and
    any reference to or evidence concerning Dr. Widmer’s training as a family
    practice physician, including Dr. Widmer’s CME records. 5 At the close of
    his case-in-chief, T.D. again sought to admit Dr. Widmer’s CME records.
    The district court maintained the same ruling, which excluded the records.
    5In
    passing, T.D.’s brief asserts the district court abused its discretion by granting
    overly broad motions in limine. He points to, as an example, the motions in limine
    regarding HCHC’s training and credentialing process and Dr. Widmer’s CME records. We
    have stated,
    The function of a motion in limine is not only to exclude during the
    voir dire examination and opening statements, reference to anticipated
    evidence claimed to be objectionable because of incompetent, irrelevant,
    immaterial or privileged but to also restrict opposing counsel in asking
    questions or making statements in offering such matters until the
    admissibility of the questionable evidence can be determined during the
    course of the trial by presenting to the court in the absence of the jury
    such evidence by offer and objection. Its objective is to control such
    matters in advance and thus avoid disclosing to the jury prejudicial
    material which may compel declaring a mistrial.
    Twyford v. Weber, 
    220 N.W.2d 919
    , 922–23 (Iowa 1974). Here, the district court did not
    abuse its discretion by granting the motions in limine. Any reference to negligent training
    or credentialing would be a new claim prejudicial to the defense, as previously determined
    by the district court. It was appropriate to grant the motions in limine until the
    admissibility of the evidence was determined by offer of proof. 
    Id. at 923.
                                        22
    Defendants claim T.D. failed to preserve error on the admissibility
    of Dr. Widmer’s CME records. “If the ruling excludes evidence, a party
    informs the court of its substance by an offer of proof, unless the
    substance was apparent from the context.” 
    Id. r. 5.103(a)(2).
    In this case,
    T.D. made the following offer of proof:
    It’s a long-standing rule in Iowa that evidence may be
    introduced to impeach an expert witness or to lessen the
    weight of his expert opinion or qualifications. . . . And since
    we know Dr. Widmer will testify as an expert witness, it’s
    Plaintiff’s position that we’re entitled to introduce evidence
    that will lessen the weight of his opinion and also to raise
    doubts about the quality of his expertise.
    Dr. Widmer’s CME records are relevant and admissible for
    this purpose. Even had Dr. Widmer not been designated as
    an expert witness, this evidence is relevant to call into
    question the professional judgment he exercised in the
    delivery of [T.D.] and also the expected testimony . . . to give
    in his defense that he—he did not need more than two
    maneuvers. . . .
    T.D. concluded his offer of proof by providing the court with Dr. Widmer’s
    CME records, a collection of discovery relevant to the CMEs, and a
    breakdown of the type of CMEs Dr. Widmer obtained.
    “The purpose of an offer of proof is to give the trial court a more
    adequate basis for its evidentiary ruling and to make a meaningful record
    for appellate review . . . .” State v. Ritchison, 
    223 N.W.2d 207
    , 212 (Iowa
    1974). We conclude T.D.’s offer of proof provided the district court with
    an adequate basis and provided our court with a meaningful record for
    review. It is clear T.D. sought to introduce CME records to show a breach
    in Dr. Widmer’s standard of care and to lessen the weight of his expert
    opinion.
    We now turn to the merits of T.D.’s claim. Relevant evidence is
    admissible, unless provided otherwise. See Iowa R. Evid. 5.402. However,
    “[i]rrelevant evidence is not admissible.” 
    Id. Evidence is
    relevant if “[i]t
    23
    has any tendency to make a fact more or less probable than it would be
    without the evidence; and . . . [t]he fact is of consequence in determining
    the action.” 
    Id. r. 5.401.
    1. CME records to show breach in the standard of care. “A physician
    is liable for injury to a patient caused by failure of the physician to apply
    that degree of skill, care, and learning ordinarily possessed and exercised
    by other physicians in similar circumstances.” 
    Speed, 240 N.W.2d at 904
    .
    In other words, “[a] physician owes a duty to his patient to exercise the
    ordinary knowledge and skill of his or her profession” when providing care
    and treatment. J.A.H. ex rel. R.M.H. v. Wadle & Assocs., P.C., 
    589 N.W.2d 256
    , 260 (Iowa 1999).        Dr. Widmer thus owed a duty to exercise “the
    ordinary knowledge and skill” of his profession during T.D.’s delivery, and
    if that standard was violated, he is liable for injuries. See 
    id. The question
    becomes whether Dr. Widmer’s CME records have a tendency to make a
    fact, that is of consequence to his outlined duty, more or less probable.
    See Iowa R. Evid. 5.401.
    T.D.’s brief reviewed the general purpose of CME credits and
    canvased Iowa’s requirements of CME hours for physicians. According to
    T.D.’s calculation, Dr. Widmer’s CME records show, out of approximately
    four hundred hours of CME credits during the relevant timeframe, only
    eight hours were potentially related to obstetrics. Obstetrics accounted
    for less than two percent of his overall CME credits, although obstetrics
    accounted for five to ten percent of his overall practice.        T.D.’s theory
    concludes   Dr. Widmer’s      lack   of    CME   credit   hours   in   obstetrics
    demonstrates he did not possess the same degree of skill, care, and
    learning as other physicians in similar circumstances.
    We are not convinced Dr. Widmer’s CME records make such bold
    statements. This evidence simply reflects the fact that Dr. Widmer has
    24
    discretion in the type and amount of credit hours selected. No evidence
    was produced in T.D.’s offer of proof recognizing the type and amount of
    CMEs obtained by similarly situated doctors.          More importantly,
    Dr. Widmer’s type and amount of credit hours are inconsequential in
    determining T.D.’s action—whether Dr. Widmer violated his standard of
    care on the day he delivered T.D. We conclude Dr. Widmer’s CME records
    are irrelevant to show a breach in that standard of care. Therefore, the
    district court did not abuse its discretion.
    2. CME records for impeachment. We must next address whether
    Dr. Widmer’s CME records were admissible as impeachment evidence.
    Ordinarily, impeachment evidence is admissible if it is relevant to
    undermining the credibility of the witness being impeached. See State v.
    Turecek, 
    456 N.W.2d 219
    , 224 (Iowa 1990).       In the case of an expert
    witness, evidence may be introduced “to lessen the weight of his expert
    opinion.” Ipsen v. Ruess, 
    241 Iowa 730
    , 734, 
    41 N.W.2d 658
    , 661 (1950)
    (quoting 32 C.J.S. Evidence § 571 (now found at 32A C.J.S. Evidence
    § 996, at 78 (2008))).
    Dr. Widmer testified, in his expert opinion, the maternal maneuvers
    he used to deliver T.D. met the standard of care. T.D. asserts the CME
    records would have weakened Dr. Widmer’s credibility as an expert and he
    was entitled to introduce the impeachment evidence.
    Defendants compare this issue to Campbell v. Vinjamuri, 
    19 F.3d 1274
    (8th Cir. 1994), and argue Dr. Widmer’s CME records were properly
    excluded. We think this case is distinguishable. Campbell involved similar
    impeachment evidence during a medical malpractice trial. The deposition
    of Dr. Vinjamuri revealed “he was not board certified in anesthesiology as
    he had, on three or four occasions, failed the board certifying
    examination.”   
    Id. at 1267.
    The district court found the board failures
    25
    irrelevant and inadmissible, but evidence that Dr. Vinjamuri was not
    board certified was allowed to go before the jury.         
    Id. On cross-
    examination, Campbell sought to use Dr. Vinjamuri’s test failures to
    impeach his credibility as an expert, but the district court refused. 
    Id. The United
    States Court of Appeals for the Eighth Circuit affirmed
    on appeal. 
    Id. at 1278.
    However, unlike Dr. Widmer, Dr. Vinjamuri gave
    what was classified as limited expert testimony and the court did “not
    decide whether a different result would be warranted had Vinjamuri given
    more extensive expert testimony.” 
    Id. at 1277
    & n.2. The court reasoned
    Vinjamuri’s test failures had no connection to whether he met the
    standard of care in his treatment. 
    Id. at 1277
    . His reason for the lack of
    certification was deemed of limited significance, but as the court pointed
    out “[i]t [was] sufficient that the jury was given the information that
    Vinjamuri was not board certified in his specialty.” 
    Id. In contrast
    to Dr. Vinjamuri’s limited expert testimony in Campbell,
    Dr. Widmer was designated as an expert and provided his expert opinion
    testimony. Further, evidence that Dr. Vinjamari was not board certified
    was before the jury and that evidence was found to be sufficient. The same
    is not true for Dr. Widmer; there is no evidence before the jury concerning
    the type and amount of his CME credits. T.D. does not seek to impeach
    Dr. Widmer with evidence of the reason for his limited CME credits in
    obstetrics.   He seeks to introduce impeachment evidence as a way of
    informing the jury that Dr. Widmer has limited CME credits in obstetrics.
    We are not inclined to reach the same conclusion as the Eighth Circuit in
    Campbell.
    We agree with T.D.’s argument that the district court should have
    allowed Dr. Widmer’s CMEs to be used for impeachment purposes. The
    cross-examination of Dr. Widmer with his own CME records may have
    26
    lessened the weight of his expert opinion. See 
    Ipsen, 241 Iowa at 734
    , 41
    N.W.2d at 661; see also Heinz v. Heinz, 
    653 N.W.2d 334
    , 342 (Iowa 2002)
    (“The purpose of cross-examination is to test the veracity of statements a
    witness made and to weaken or disprove the opposing case.”). The CME
    records would have shown the jury that Dr. Widmer committed relatively
    few hours of his continuing medical education to obstetrics. Therefore,
    the CME records were relevant to undermining the credibility of
    Dr. Widmer and were admissible as impeachment evidence on this narrow
    issue. See 
    Turecek, 456 N.W.2d at 224
    .
    We must next determine whether reversible error was committed by
    the omission of this evidence. Error in excluding evidence may be claimed
    “only if exclusion of the evidence affected a party’s substantial rights.”
    Scott v. Dutton-Lainson Co., 
    774 N.W.2d 501
    , 503 (Iowa 2009); see Iowa R.
    Evid. 5.103(a). Reversal is warranted only if the exclusion of Dr. Widmer’s
    CME records affected T.D.’s substantial rights. See 
    Scott, 774 N.W.2d at 503
    . Because we are dealing with a nonconstitutional error, we employ
    the harmless error analysis. See State v. Russell, 
    893 N.W.2d 307
    , 314
    (Iowa 2017).    “We presume prejudice and reverse unless the record
    affirmatively establishes otherwise.” 
    Id. Upon our
    review of the record, we conclude the error was harmless.
    The district court’s exclusion of the CME records did not affect T.D.’s
    substantial rights.   At trial, T.D. was able to introduce other evidence
    concerning Dr. Widmer’s training and lack of experience, which lessened
    the weight of his expert opinion. T.D.’s expert testified to the proper use
    of maternal and fetal maneuvers when shoulder dystocia is encountered.
    His expert specifically stated Dr. Widmer did not possess the knowledge
    and experience of proper maneuvers and that Dr. Widmer “didn’t ever have
    a prior experience” with fetal maneuvers. T.D. also played the deposition
    27
    of Dr. Widmer for the jury. The deposition elicited from Dr. Widmer the
    fact he could not recall attending any seminars or practice review courses
    specific to obstetrics. On cross-examination, Dr. Widmer admitted to not
    knowing multiple types of fetal maneuvers. In fact, Dr. Widmer testified
    he had never performed a number of relevant fetal maneuvers used to
    resolve shoulder dystocia. We conclude this evidence, in addition to the
    opinions of many experts over the eight-day trial, weakened the credibility
    of Dr. Widmer’s expert opinion.
    The record affirmatively established the exclusion of Dr. Widmer’s
    CME records did not affect T.D.’s substantial rights. There is no error
    warranting reversal in this case. See Tucker v. Caterpillar, Inc., 
    564 N.W.2d 410
    , 414 (Iowa 1997).
    C. Undisclosed Expert Opinions.
    1. Direct testimony.        At trial, Dr. Widmer testified on direct
    examination:
    Q. Do you have an opinion as to whether the
    maneuvers you used were in conformity with the standard of
    care?
    MR. GOODMAN: Undisclosed opinion.
    THE COURT: Overruled.
    A. I believe I did.
    T.D. contends this four-word standard of care opinion required prior
    disclosure, which Dr. Widmer failed to do, and the district court erred by
    allowing him to testify.     We consider T.D.’s argument against this
    backdrop.
    Iowa Code chapter 688 contains a provision governing the
    “[d]isclosure of expert witnesses in liability cases involving licensed
    professionals” and states,
    28
    A party in a professional liability case brought against a
    licensed professional pursuant to this chapter who intends to
    call an expert witness of their own selection, shall certify to
    the court and all other parties the expert’s name,
    qualifications and the purpose for calling the expert . . . .
    Iowa Code § 668.11(1) (2017). The parties do not dispute the timeliness of
    Dr. Widmer’s designation pursuant to section 668.11. See 
    id. (requiring disclosure
    of expert witness for defendant “within ninety days of plaintiff’s
    certification”). According to his expert designation, Iowa’s rules of civil
    procedure then required Dr. Widmer to disclose:
    (1) The subject matter on which the witness is expected
    to present evidence under Iowa Rules of Evidence 5.702,
    5.703, or 5.705.
    (2) A summary of the facts and opinions to which the
    witness is expected to testify.
    Iowa R. Civ. P. 1.500(2)(c)(1)–(2).   Defendants’ certification designating
    Dr. Widmer conveyed, among other things, that he would “testify on the
    issues of standard of care, causation and damages.” Defendants’ timely
    certification of experts designated Dr. Widmer and indicated:
    Dr. Widmer is qualified to testify in this case based on his
    education, training, and experience, his review of the medical
    records of [mother and T.D.], birth video, deposition testimony
    in this case, and his care and treatment of [mother and T.D.].
    The purpose of calling Dr. Widmer will be to have him testify on
    the issues of standard of care, causation and damages.
    Dr. Widmer is expected to testify at trial consistent with his
    deposition testimony given in this case.
    (Emphasis added.) We conclude that subject matter was plainly disclosed
    by Dr. Widmer. See 
    id. r. 1.500(2)(c)(1).
    We also conclude the second prong of rule 1.500(2)(c) was satisfied.
    Prior to Dr. Widmer’s designation, T.D. conducted an eight-hour
    deposition of Dr. Widmer.      This deposition, T.D. claims, was before
    Dr. Widmer’s expert designation and was therefore limited to his capacity
    as a treating physician, not as an expert.       T.D.’s timeline for expert
    29
    designation is correct, but his argument overlooks actual testimony
    elicited from Dr. Widmer by T.D.’s counsel:
    Q. And you’re familiar with that method of properly
    doing the McRoberts maneuver? A. I would say yes.
    Q. And did you witness them perform the McRoberts
    maneuver satisfactorily? A. I believe so.
    ....
    Q. Was the McRoberts maneuver successful?            A. I
    believe so.
    Q. And do you believe it was properly executed? A. I
    do.
    ....
    Q. Were these maneuvers that you ordered effective,
    the application of the suprapubic pressure and the McRoberts
    maneuver? A. Yes
    Q. And would you please tell . . . why those maneuvers
    that you ordered were effective? A. They were performed as
    needed, and the baby was delivered.
    Q. And the baby was delivered, what, within a minute
    after the head was delivered, the entire body was delivered?
    A. I believe by our time we thought a minute, 35.
    Q. And you said you usually like to see the baby
    delivered three to five minutes after the head was delivered?
    A. Yes.
    Q. And that was well within your time frame; correct?
    A. It was.
    This line of questioning—before his designation as an expert witness—
    makes clear Dr. Widmer believed the maneuvers he used were in
    conformity with the standard of care. Even if T.D. should “be able to expect
    that a treating physician’s testimony will not include opinions on
    reasonable standards of care,” the deposition of Dr. Widmer, in fact, did.
    See 
    Hansen, 686 N.W.2d at 482
    (addressing expert witness designation
    under Iowa Code section 668.11). The distinction between Dr. Widmer as
    30
    a treating physician and Dr. Widmer as a designated expert, for purposes
    of this disclosure, is inconsequential.        We conclude Dr. Widmer’s
    deposition disclosed a summary of facts and opinions to which he was
    expected to testify. See Iowa R. Civ. P. 1.500(2)(c)(2).
    Relatedly, Dr. Widmer’s direct testimony at trial was consistent with
    and within the scope of his deposition testimony. The Iowa Rules of Civil
    Procedure indicate, “The expert’s direct testimony at trial may not be
    inconsistent with or go beyond the fair scope of the expert’s disclosures,
    report, deposition testimony, or supplement thereto.” 
    Id. r. 1.508(4).
    T.D.
    claims Dr. Widmer’s four-word standard of care opinion was in violation
    of rule 1.508(4)’s mandate. We disagree. At trial, the direct examination
    of Dr. Widmer inquired into whether he believed the maternal maneuvers
    conformed to the standard of care. His response, “I believe I did,” was
    entirely consistent with his previous deposition testimony, which conveyed
    his belief that such maternal maneuvers were successful, proper, and
    effective. Moreover, Dr. Widmer’s direct testimony did not go beyond the
    fair scope of his disclosures or deposition testimony.            His expert
    designation plainly stated, “The purpose of calling Dr. Widmer will be to
    have him testify on the issues of standard of care, causation and
    damages.” He testified exactly to that. Dr. Widmer’s four-word testimony
    on the standard of care was well within the disclosed scope, and his direct
    testimony regarding the maternal maneuver standard of care was
    decidedly less detailed than his responses from the deposition testimony.
    The district court did not err by allowing Dr. Widmer to testify on his expert
    opinions.
    2. Fetal heart rate notes. On the sixth day of trial, during redirect
    examination, Dr. Widmer referred to a single page of handwritten notes.
    He testified to creating the notes “last Friday” when he reviewed the birth
    31
    video and stated his notes would assist in recalling the times he heard
    fetal heart rates without the need to watch the entire birth video. The
    single page of handwritten notes contained nothing more than a column
    of video time stamps with the corresponding fetal heart rates. 6 Only after
    T.D.’s counsel published Dr. Widmer’s notes to the jury did defendants
    later move to admit the notes as demonstrative evidence.
    T.D. argues, as he did at trial, that Dr. Widmer provided an
    undisclosed opinion on the fetal heart rate in the birth video. Defendants
    take the position the handwritten notes were simply a summary of
    Dr. Widmer’s observations used to refresh his recollection.                        We are
    persuaded to agree with defendants.
    The disclosure requirements of rule 1.508 are generally limited to
    physicians retained as experts for purposes of litigation or for trial. See
    
    Hansen, 686 N.W.2d at 483
    ; Iowa R. Civ. P. 1.508. However, “even treating
    physicians may come within the parameters of rule [1.508] when they
    begin to assume a role in the litigation analogous to that of a retained
    expert.”      
    Hansen, 686 N.W.2d at 483
    (quoting Morris-Rosdail v.
    Schechinger, 
    576 N.W.2d 609
    , 612 (Iowa Ct. App. 1998)). This will occur
    if the treating physician focuses more on the legal issues in pending
    litigation and less on the medical facts and opinions associated in treating
    a patient. 
    Id. It is
    clear Dr. Widmer does not satisfy Hansen’s threshold test as a
    retained expert. This very narrow issue focuses on whether Dr. Widmer’s
    handwritten notes reflect opinions in anticipation of litigation.                        We
    conclude they do not. Dr. Widmer’s notes were derived from the birth
    video—when he was T.D.’s treating physician. His notes are the summary
    6Dr.  Widmer testified he calculated the fetal heart rate at a given time by listening
    to the birth video and counting on his watch.
    32
    of his observations and opinions during T.D.’s birth.          Dr. Widmer’s
    handwritten notes focused more on the medical facts and opinions of
    T.D.’s birth and less on the legal issues in the pending trial. See 
    id. D. Access
    to Birth Video. T.D.’s birth was captured on a twenty-
    one minute video. The birth video, recorded by T.D.’s aunt, depicted the
    delivery team’s (Dr. Widmer and the HCHC nurses) efforts during T.D.’s
    birth. Experts from both parties reviewed the birth video prior to the trial.
    Later, T.D. offered the birth video into evidence, and it was admitted
    without objection. At trial, the jury first viewed the twenty-one minute
    birth video in its entirety.     Then, throughout the trial, the record
    demonstrates the birth video was played, paused, and replayed no less
    than forty-one more times. In addition, defendants used ten screenshots
    from the birth video during direct examination of their expert witnesses.
    The ten screenshots were similarly admitted into evidence without
    objection.
    Although the birth video was admitted into evidence, the district
    court denied T.D.’s request for the video to be fully accessible to the jury
    during deliberations. It did, however, allow full access to defendants’ ten
    screenshots. The district court instructed the jury about the birth video
    as follows:
    You’ll have the exhibits in the jury room. As stated by the
    lawyers in the case, if you wish to review the birth tape again,
    we will have that set up. We will play it from beginning to end.
    Actually, I think we probably do it in here, not in the jury room
    because that TV is bigger and you have a little bit more room,
    and I think the acoustics would probably be a bit better. So
    we would do that, just let somebody know. Very simple, okay?
    Consequently, during deliberations, the jury asked to view the birth video.
    The district court permitted the video to be played once through without
    33
    the ability to pause, stop, or rewind. T.D. takes issue with the district
    court’s restrictions and asserts the district court abused its discretion.
    Iowa Rule Civil Procedure 1.926(2) provides, “When retiring to
    deliberate, jurors . . . shall take with them all exhibits in evidence except
    as otherwise ordered.” Whether exhibits are submitted to the jury during
    deliberations is a matter within the district court’s discretion. See State v.
    Thompson, 
    326 N.W.2d 335
    , 337 (Iowa 1982) (reasoning a district court’s
    discretion provided by the rules of criminal procedure is “much the same
    in civil cases”); see also Brooks v. Holtz, 
    661 N.W.2d 526
    , 532 (Iowa 2003)
    (submission of exhibits to jury in civil case within district court’s
    discretion).
    In Brooks, we upheld a district court’s decision to withhold video of
    the accident scene from jury deliberations, even though “the tape was
    shown to the jury several times during the trial and was admitted into
    evidence” and the plaintiffs requested the jury be allowed to have the 
    video. 661 N.W.2d at 532
    . We noted when certain types of evidence are available
    to the jury, “such evidence might be given ‘disproportionate importance in
    relation to other trial testimony, for which the jurors were required to call
    upon their recollection only.’ ” 
    Id. (quoting State
    v. Baumann, 
    236 N.W.2d 361
    , 366 (Iowa 1975)).
    Like Brooks, “[t]his judgment call was one for the trial court to
    make.”    
    Id. In deciding
    whether to submit the birth video for jury
    deliberation, the district court stated,
    What I’ll do, and what I’ve done in the past, we’ll wait
    and see if they want to see it again and what context.
    Sometimes they put a context, if it’s for a particular purpose,
    maybe just general. Wait until it comes up. . . . Generally in
    these situations—situation’s usually in a criminal case—I let
    them play it once. Play it just as it was played, one time, and
    they can resolve any issues they have regarding that.
    34
    If there’s some specific section they want to see to
    confirm or not confirm something that was said by an expert,
    that usually comes up, I play back the whole thing.
    ....
    I think they should have at least one shot at it, see the
    whole thing again, just as it was played in court. So they
    will—I’ll tell them at the end of the thing, if you want to look
    at it, let us know, you can look at it.
    It is clear the district court was concerned with the context of the jury’s
    reason for viewing the video.             To avoid giving a disproportionate
    importance to specific sections of the video, the district court’s judgment
    call was to play the entire video once. This exercise of discretion was not
    clearly unreasonable. See 
    id. Unlike the
       caselaw    T.D.    cites,   the   unique     situation    here
    contemplated extensive competing expert opinions over an eight-day trial.
    See, e.g., State v. Jackson, 
    387 N.W.2d 623
    , 629 (Iowa Ct. App. 1986)
    (holding the district court did not abuse its discretion in granting jury’s
    request to view crime scene video without limitation); State v. Hernandez,
    No. 12–0219, 
    2013 WL 1452958
    , at *6 (Iowa Ct. App. Apr. 10, 2013)
    (concluding the district court was within its discretion in allowing the jury
    unfettered access to audio recordings of the criminal event). In its totality,
    the birth video lasted twenty-one minutes. Yet, an overwhelming majority
    of the forty-one paused or replayed sections focused on the one minute
    and ten seconds following recognition of shoulder dystocia. In view of the
    roughly nineteen minutes of extraneous details on the video, and to be
    quite frank, the personal nature of the birth footage, 7 the district court
    was correct to prevent the video from becoming disproportionately
    7The    birth video captured the reality of T.D.’s delivery, which upon its first
    publication to the jury, caused one juror to “apparently [become] faint—fainted, or
    [become] ill.”
    35
    important in the face of vast expert opinions. The district court did not
    abuse its discretion by limiting access to the birth video.
    IV. Conclusion.
    For the aforementioned reasons, we affirm the district court’s
    judgment.   Specifically, we conclude the district court did not commit
    reversible error in the specifications of negligence it submitted to the jury.
    We determine Dr. Widmer’s CME records were not admissible to show a
    breach in the standard of care. However, although it was an abuse of
    discretion for the district court to prohibit the use of CME records as
    impeachment evidence, the error was harmless.          Further, defendants’
    expert opinion testimony was properly disclosed and did not reflect an
    opinion in anticipation of litigation. We also conclude the district court
    did not abuse its discretion by limiting the jury’s access to the birth video.
    AFFIRMED.
    All justices concur except Waterman, J., who takes no part.
