    HECHT, Justice.
    The defendant killed her longtime boyfriend. At trial she raised a
    defense of justification based on evidence of battered women’s syndrome
    and a defense of insanity based on various diagnoses including
    depression and an anxiety disorder. She was convicted of first-degree
    murder. On appeal, she alleges the district court erred in denying her
    motion for mistrial and by giving improper jury instructions on
    justification, insanity, and reasonable doubt.           Finding no error in the
    record, we affirm the conviction.
    I. Background Facts and Proceedings.
    In response to a 911 call shortly before 2:00 a.m. on July 19,
    2009, police found Denise Frei sitting on the front porch of the home she
    shared with Curtis Bailey in Marengo, Iowa.1 She had blood on her shirt
    and hands.         Inside, Bailey’s dead body lay on the living room floor,
    beaten severely with blunt objects.            Frei told the police she had been
    upstairs and overheard a drug deal “gone bad” and then found Bailey’s
    body. Later, however, she admitted that she had killed Bailey with the
    help of her eighteen-year-old son and his girlfriend.
    Frei was charged with first-degree murder. At trial, she relied on
    defenses of justification and insanity. She testified that Bailey subjected
    her to humiliating and degrading emotional, verbal, and sexual abuse
    and that he threatened to kill her children and grandchild if she ever left
    him.    She described Bailey as an extremely jealous and controlling
    person who checked her sales receipts after shopping trips to see if her
    purchases had been rung up by a male cashier. If the receipts evidenced
    the involvement of a male cashier, Bailey forced her to return the items
    1Frei   described Bailey as her common law husband.
    3
    for a refund. He allegedly cut her off from her family, including her adult
    sons and her grandchild. Frei testified that she had tried to leave Bailey
    at least once and had talked about it on other occasions but that he had
    threatened to slit the throats of her children and grandchild if she did,
    and that he had told her that even if she killed herself, he would still
    harm her family.    She testified that she tried to kill Bailey on three
    previous occasions by giving him doses of morphine and insulin.
    Frei devised a plan in early July 2009 to get Bailey drunk enough
    to pass out and then smother him by wrapping his face in Saran Wrap.
    She believed that if she suffocated him with the plastic wrap it would
    leave no marks and it would appear Bailey had died as a consequence of
    an overdose or heart attack. She sought the help of her eighteen-year-
    old son, Jacob, and his girlfriend, Jessica. Frei told Bailey that she and
    Jessica would engage in sex acts together while he watched if he would
    drink a shot of vodka for each sex act they performed.        Bailey agreed
    and, on the morning of Saturday, July 18, told his work acquaintances
    about the ménage à trois that was to take place that night.
    That night, Frei and Jessica followed their plan, serving Bailey
    shots of vodka until he passed out in the living room.              Jessica
    summoned Jacob to the house, and Frei bound Bailey’s wrists with
    plastic wrap. As his face was being wrapped, however, Bailey woke up
    and struggled to free himself.   Frei, Jacob, and Jessica each grabbed
    objects nearby, including a rock and a candy dish, and struck Bailey
    approximately thirty times until he died. The three cleaned up the scene,
    and Jacob and Jessica left the house. Frei called 911 and reported a
    false story about the circumstances surrounding Bailey’s death. She told
    the police that Bailey died during a drug deal gone bad—that while she
    was upstairs he had let two men into the house to purchase drugs and
    4
    that she heard them struggle and came down to find Bailey dead. When
    she later learned that her son had confessed his participation in the
    incident, she returned to the police station and admitted her own
    involvement.
    Frei offered the trial testimony of Dr. Marilyn Hutchinson, who
    testified that Frei suffered from depression, posttraumatic stress
    syndrome (PTSD), battered women’s syndrome (BWS),2 and possibly an
    anxiety disorder. Dr. Hutchinson explained that she believed Frei had
    endured a tremendous amount of sexual and emotional abuse from
    Bailey, childhood sexual and physical abuse, and adult physical abuse
    from her former husband.            She opined this extensive history of abuse
    distorted Frei’s thoughts and feelings and impacted her ability to make
    rational decisions. Dr. Hutchinson further testified that at the time of
    the murder, Frei would have had the ability to distinguish between right
    and wrong, but that Frei would not have understood right and wrong the
    way people without these mental health issues understand them.                           In
    particular, Dr. Hutchinson opined that Frei would have understood it
    was legally wrong to kill Bailey but would have also believed that it was
    right to protect her children from his threat to kill them.
    The State offered expert testimony from Dr. Michael Taylor, who
    concluded that Frei did not suffer from any psychiatric disorder and that
    she understood the nature and quality of her acts when she plotted to
    kill Bailey. He specifically rejected Dr. Hutchinson’s posttraumatic stress
    syndrome disorder diagnosis, noting Frei had denied all of the normal
    2In this case, Frei’s expert testified that she believed Frei suffered from “battered
    women’s syndrome.” This condition is also sometimes referred to as “battered woman
    syndrome,” “battered person syndrome,” or “battered spouse syndrome.” For clarity, we
    use the term utilized by the expert and the parties in this case.
    5
    symptoms of PTSD during his interview with her. The State also relied
    on Frei’s own admissions to disprove her justification defense—
    specifically that she planned Bailey’s death for a week-and-a-half to two
    weeks and that she tried to make it look like an accidental death rather
    than a murder.     The State also introduced evidence that she made
    statements suggesting proceeds from life insurance on Bailey’s life would
    allow her to pay off debts on the restaurant she owned with Bailey.
    The jury found Frei guilty. On appeal, she raises four issues: that
    the district court erroneously (1) instructed the jury on the elements of a
    justification defense, (2) instructed the jury that the defendant bore the
    burden to prove an insanity defense, (3) instructed the jury on the
    definition of reasonable doubt, and (4) denied Frei’s motion for mistrial
    after the prosecution violated a ruling in limine during opening
    statements.
    II. Scope of Review.
    We review challenges to jury instructions for correction of errors at
    law. State v. Marin, 
    788 N.W.2d 833
    , 836 (Iowa 2010); see also Iowa R.
    App. P. 6.907. “ ‘We review the related claim that the trial court should
    have given the defendant’s requested instructions for an abuse of
    discretion.’ ” Marin, 788 N.W.2d at 836 (quoting Summy v. City of Des
    Moines, 
    708 N.W.2d 333
    , 340 (Iowa 2006)). “Error in giving or refusing
    to give a particular instruction warrants reversal unless the record shows
    the absence of prejudice.” Id. “ ‘When the error is not of constitutional
    magnitude, the test of prejudice is whether it sufficiently appears that
    the rights of the complaining party have been injuriously affected or that
    the party has suffered a miscarriage of justice.’ ”   Id. (quoting State v.
    Gansz, 
    376 N.W.2d 887
    , 891 (Iowa 1985)).              When the alleged
    instructional error is of constitutional magnitude, the burden is on the
    6
    State to prove lack of prejudice beyond a reasonable doubt.           State v.
    Hanes, 
    790 N.W.2d 545
    , 550 (Iowa 2010).           We review a trial court’s
    denial of a motion for mistrial for an abuse of discretion. State v. Greene,
    
    592 N.W.2d 24
    , 30 (Iowa 1999).
    III. Discussion.
    A.   Jury Instructions on Justification Defense.            Iowa Code
    section 704.3 (2011) prescribes the elements of a justification defense.
    A person is justified in the use of reasonable force
    when the person reasonably believes that such force is
    necessary to defend oneself or another from any imminent
    use of unlawful force.
    Iowa Code § 704.3.
    “Reasonable force” is defined as
    that force and no more which a reasonable person, in like
    circumstances, would judge to be necessary to prevent an
    injury or loss and can include deadly force if it is reasonable
    to believe that such force is necessary to avoid injury or risk
    to one’s life or safety or the life or safety of another, or it is
    reasonable to believe that such force is necessary to resist a
    like force or threat. Reasonable force, including deadly force,
    may be used even if an alternative course of action is
    available if the alternative entails a risk to life or safety, or
    the life or safety of a third party, or requires one to abandon
    or retreat from one’s dwelling or place of business or
    employment.
    Id. § 704.1.
    When interpreting and applying these statutes, we have explained
    that “the test of justification is both subjective and objective. The actor
    must actually believe that he is in danger and that belief must be a
    reasonable one.” State v. Elam, 
    328 N.W.2d 314
    , 317 (Iowa 1982). Frei
    takes issue with this characterization of the justification defense. She
    contends the “objective” element of the justification—requiring the
    defendant to act and perceive as a reasonable person—is incompatible
    with the requirement that the State must prove the defendant possessed
    7
    the level of culpability required to support a conviction for the charged
    crime. She asserts that if the defendant possesses the subjective belief
    that her actions are justified, then “the objective reasonableness of that
    belief should not matter.” Accordingly, she contends the district court
    erred when it rejected her proposed instruction defining “reasonable
    force” as “only the amount of force a reasonable person or a person with
    the Defendant’s alleged degree of mental illness would find necessary to
    use under the circumstances.” Frei contends the district court further
    erred in denying her requested justification instruction, which would
    have permitted the jurors to acquit her if they found she subjectively
    believed her actions were justified without considering whether her
    perception of danger or belief regarding the availability of an alternative
    course of action was reasonable. The given justification instruction, by
    contrast, retained an objective reasonableness requirement.
    Frei contends the decision of our court of appeals in State v. Price
    supports her contention that the standard should be subjective.        See
    State v. Price, No. 07–1659, 
    2008 WL 5234351
     (Iowa Ct. App. Dec. 17,
    2008).   In its discussion of the admissibility of BWS evidence in that
    case, the court noted:
    [W]e think the expert’s testimony would have given the jury
    information that it needed to understand the significance
    and meaning of the victim’s conduct and to understand the
    defendant’s reaction to that conduct . . . . Furthermore, we
    agree with those jurisdictions that have concluded that while
    evidence of battered women’s syndrome is not in and of itself
    a defense, “its function is to aid the jury in determining
    whether a defendant’s fear and claim of self-defense are
    reasonable.”
    Id. at *6 (citation omitted) (quoting State v. Edwards, 
    60 S.W.3d 602
    , 613
    (Mo. Ct. App. 2001)).
    8
    While the decision in the unreported Price decision is not binding
    authority for this court, it appears to be the only decision of an appellate
    court in the state addressing the admissibility of expert testimony about
    BWS offered by a defendant in furtherance of her justification defense.3
    We note the conclusion reached by the court of appeals in Price that such
    evidence is relevant to both the defendant’s subjective belief and the
    reasonableness of her belief is consistent with the results reached by
    several other courts across the country. See, e.g., People v. Humphrey,
    
    921 P.2d 1
    , 9 (Cal. 1996); Smith v. State, 
    486 S.E.2d 819
    , 822 (Ga.
    1997); State v. Hennum, 
    441 N.W.2d 793
    , 798 (Minn. 1989); State v.
    Kelly, 
    478 A.2d 364
    , 376–77 (N.J. 1984); State v. Seeley, 
    720 N.Y.S.2d 315
    , 321 (Sup. Ct. 2000); State v. Koss, 
    551 N.E.2d 970
    , 973–74 (Ohio
    1990).      The decisions of these courts have not eliminated the
    reasonableness requirement            from a justification defense when a
    defendant relies on BWS. But see Bechtel v. State, 
    840 P.2d 1
    , 11 (Okla.
    Crim. App. 1992) (modifying jury instructions, in BWS cases, to eliminate
    requirement that defendant “reasonably” believe use of deadly force is
    necessary to avoid imminent danger).                  Instead, these cases have
    examined       the    appropriate      level    of    contextualization       for    the
    reasonableness inquiry. See Smith, 486 S.E.2d at 823. As applied to a
    battered woman, an appropriately specific reasonableness inquiry might
    consider objective facts about the batterer, any history of violence, any
    failed attempts to escape abuse, and any other facts relevant under the
    3We have twice addressed the admission of testimony regarding battered
    women’s syndrome in criminal trials, but neither case involved a defendant’s offer of
    BWS evidence. Instead, the evidence was used by the State against the defendant—to
    explain an abuse victim’s recantation of an accusation, State v. Griffin, 
    564 N.W.2d 370
    ,
    374 (Iowa 1997), or to prove the defendant confined the victim against her will, State v.
    Rodriquez, 
    636 N.W.2d 234
    , 246 (Iowa 2001).
    9
    circumstances. Further, expert testimony can aid in cautioning jurors
    that the behavior of battered women should not be lightly dismissed as
    inherently unreasonable. These cases do not, however, establish that an
    appropriate reasonableness inquiry extends only as far as a specific
    defendant’s    actual,   subjective   beliefs     regarding   the   surrounding
    circumstances.    Accordingly, Frei’s reliance on Price, and by extension
    the authorities from other jurisdictions, does not support her argument
    for a purely subjective test for justification.
    The State argues that the jury instructions given by the court in
    this case accurately express the legal elements of a justification defense
    as provided by sections 704.1 and 704.3 and interpreted by our prior
    caselaw.   We agree.     Frei’s proposal for an entirely subjective test of
    justification is incompatible with the clear mandate of sections 704.1 and
    704.3 requiring the actions and perceptions of the defendant be tested
    against a reasonableness standard.         The district court did not err in
    instructing the jury as it did.
    B.      Reasonable Doubt Instruction.            Frei requested a jury
    instruction on reasonable doubt that read as follows:
    The burden is on the State to prove Denise Frei guilty
    beyond a reasonable doubt.
    A “reasonable doubt” is such a doubt as fairly and naturally
    arises in our mind and by reason of which you cannot say
    that you have a full and abiding conviction of the guilt of the
    defendant; and if, after considering all of the circumstances
    as disclosed by the evidence, you find your mind wavering or
    vacillating, then you have a reasonable doubt, and the
    defendant is entitled to the benefit of such doubt and you
    must acquit her. A reasonable doubt may arise from the
    evidence in the case or it may arise from a lack or failure of
    evidence produced by the State, and it must be such a doubt
    as would cause a reasonable, prudent and considerate man
    to pause and hesitate before acting in the graver and more
    important affairs of life. But you should not ignore credible
    evidence to hunt for doubt, and you should not entertain
    10
    such doubt as is purely imaginary or fanciful or based on
    groundless conjecture. If, after a careful and impartial
    consideration of all evidence in the case, you have a full and
    abiding conviction of the guilt of the defendant, then you are
    satisfied beyond a reasonable doubt, otherwise you are not
    satisfied beyond a reasonable doubt.4
    The district court declined to give the instruction requested by
    Frei, electing instead to give the following instruction on the subject:
    The burden is on the State to prove Denise Leone Frei guilty
    beyond a reasonable doubt.
    A reasonable doubt is one that fairly and naturally arises
    from the evidence or lack of evidence produced by the State.
    If, after a full and fair consideration of all the evidence, you
    are firmly convinced of the defendant’s guilt, then you have
    no reasonable doubt and you should find the defendant
    guilty.
    But if, after a full and fair consideration of all the evidence or
    lack of evidence produced by the State, you are not firmly
    convinced of the defendant’s guilt, then you have a
    reasonable doubt and you should find the defendant not
    guilty.5
    Frei contends the instruction given by the district court violated her due
    process rights.
    4This proposed instruction was derived from language found in one of the
    “Uniform Jury Instructions” drafted by a special committee of the Iowa State Bar
    Association (ISBA) and published by that association prior to 2004.
    5This instruction given by the district court was derived from language found in
    the version of the ISBA’s uniform instruction on reasonable doubt extant from 2004 to
    2009. By the time of the trial of this case in August 2011, the ISBA’s uniform
    instruction on reasonable doubt had been revised to include an additional paragraph
    which provides:
    A reasonable doubt is a doubt based upon reason and common sense,
    and not the mere possibility of innocence. A reasonable doubt is the
    kind of doubt that would make a reasonable person hesitate to act. Proof
    beyond a reasonable doubt, therefore, must be proof of such a
    convincing character that a reasonable person would not hesitate to rely
    and act upon it. However, proof beyond a reasonable doubt does not
    mean proof beyond all possible doubt.
    Iowa Crim. Jury Instruction 100.10 (March 2009).
    11
    We begin our analysis by noting the clearly established proposition
    that “the Due Process Clause protects the accused against conviction
    except upon proof beyond a reasonable doubt of every fact necessary to
    constitute the crime with which he is charged.” In re Winship, 
    397 U.S. 358
    , 364, 
    90 S. Ct. 1068
    , 1073, 
    25 L. Ed. 2d 368
    , 375 (1970). “ ‘[T]aken
    as a whole, the instructions [must] correctly conve[y] the concept of
    reasonable doubt to the jury.’ ” Victor v. Nebraska, 
    511 U.S. 1
    , 5, 
    114 S. Ct. 1239
    , 1243, 
    127 L. Ed. 2d 583
    , 590 (1994) (quoting Holland v.
    United States, 
    348 U.S. 121
    , 140, 
    75 S. Ct. 127
    , 138, 
    99 L. Ed. 150
    , 167
    (1954)). The constitutional question presented here “is whether there is
    a reasonable likelihood that the jury understood the instructions to allow
    conviction based on proof insufficient to meet the Winship standard.” Id.
    at 6, 114 S. Ct. at 1243, 127 L. Ed. 2d at 591.
    Courts have struggled, however, in settling upon a serviceable
    definition of the “reasonable doubt” standard.          The choice of words
    accurately communicating the nature and extent of certitude jurors must
    have a defendant’s guilt in order to vote for a conviction is not an easy
    project. The Due Process Clause provides no definitional guidance as it
    requires no “particular form of words be used in advising the jury of the
    government’s burden of proof.”       Id. at 5, 114 S. Ct. at 1242–43, 127
    L. Ed. 2d at 590 (noting “[a]lthough this standard is an ancient and
    honored    aspect    of   our   criminal   justice   system,   it   defies   easy
    explication.”).     Yet, Supreme Court jurisprudence teaches that a
    minimum definitional threshold for the standard does exist.                   For
    example, a jury instruction characterizing reasonable doubt as “such
    doubt as would give rise to grave uncertainty” and “an actual substantial
    doubt” amounting to a “moral certainty” set the bar for the State’s
    burden of proof too low and fell below the due process threshold. Cage v.
    12
    Louisiana, 
    498 U.S. 39
    , 41, 
    111 S. Ct. 328
    , 329–30, 
    112 L. Ed. 2d 339
    ,
    342 (1990) (per curiam, overruled in part on other grounds by Estelle v.
    McGuire, 
    502 U.S. 62
    , 72 n.4, 
    112 S. Ct. 475
    , 482 n.4, 
    116 L. Ed. 2d 385
    , 399 n.4 (1991)).
    Other formulations of the reasonable doubt standard have survived
    due process scrutiny.     In Victor, the Supreme Court found no due
    process violation resulted from jury instructions in two consolidated
    cases. In one of these cases, the California state trial court’s instructions
    defined reasonable doubt as follows:
    It is not a mere possible doubt; because everything relating
    to human affairs, and depending on moral evidence, is open
    to some possible or imaginary doubt. It is that state of the
    case which, after the entire comparison and consideration of
    all the evidence, leaves the minds of the jurors in that
    condition that they cannot say they feel an abiding
    conviction, to a moral certainty, of the truth of the charge.
    Victor, 511 U.S. at 7, 114 S. Ct. at 1244, 127 L. Ed. 2d at 591–92
    (citation omitted). In the other consolidated case, a Nebraska state trial
    court defined reasonable doubt as follows:
    “Reasonable doubt” is such a doubt as would cause a
    reasonable and prudent person, in one of the graver and
    more important transactions of life, to pause and hesitate
    before taking the represented facts as true and relying and
    acting thereon. It is such a doubt as will not permit you,
    after full, fair, and impartial consideration of all the
    evidence, to have an abiding conviction, to a moral certainty,
    of the guilt of the accused. At the same time, absolute or
    mathematical certainty is not required.         You may be
    convinced of the truth of a fact beyond a reasonable doubt
    and yet be fully aware that possibly you may be mistaken.
    You may find an accused guilty upon the strong probabilities
    of the case, provided such probabilities are strong enough to
    exclude any doubt of his guilt that is reasonable.          A
    reasonable doubt is an actual and substantial doubt
    reasonably arising from the evidence, from the facts or
    circumstances shown by the evidence, or from the lack of
    evidence on the part of the State, as distinguished from a
    doubt arising from mere possibility, from bare imagination,
    or from fanciful conjecture.
    13
    Id. at 18, 114 S. Ct. at 1249, 127 L. Ed. 2d at 598 (citation omitted). The
    Supreme Court concluded both of these reasonable doubt formulations
    passed due process muster.            Id. at 22–23, 114 S. Ct. at 1252, 127
    L. Ed. 2d at 601.
    Frei contends the reasonable doubt instruction given by the
    district court in this case fell short of the applicable due process
    standard because it failed to “ ‘impress[] upon the factfinder the need to
    reach a subjective state of near certitude of the guilt of the accused.’ ”
    Id. at 15, 114 S. Ct. at 1247, 127 L. Ed. 2d at 596 (quoting Jackson v.
    Virginia, 
    443 U.S. 307
    , 315, 
    99 S. Ct. 2781
    , 2786, 
    61 L. Ed. 2d 560
    , 571
    (1979)). In particular, she posits that the “firmly convinced” formulation
    of reasonable doubt instructed upon in this case provided no real
    guidance to the jurors as to the nature or quality of doubt that would
    require an acquittal, and thus allowed them to convict her with a lesser
    quantum of certainty than is required by the Federal Constitution.6
    We approved a very similar formulation of the reasonable doubt
    standard in State v. McFarland, 
    287 N.W.2d 162
    , 163 (Iowa 1980). The
    relevant instructions in McFarland authorized the jury to convict the
    defendant only if they were “firmly and abidingly convinced” of the
    defendant’s guilt. Id. We concluded the instructions sufficiently “set out
    an objective standard for measuring the jurors’ doubts.” Id.
    6Frei also suggests “this Court can interpret the due process clause of the Iowa
    Constitution to require the use of Ms. Frei’s proposed instruction, even if the U.S.
    Supreme Court’s interpretation of the federal Constitution would not require it.” She
    makes no argument however, suggesting a different interpretation is mandated under
    the corollary due process clause in the Iowa Constitution. “As a result, prudential
    concerns ordinarily mean that where an argument that the Iowa Constitution should be
    construed differently than the United States Constitution is not presented, we assume
    for purposes of the case that the provisions should be interpreted in an identical
    fashion.” State v. Feregrino, 
    756 N.W.2d 700
    , 703–04 n.1 (Iowa 2008).

    Since Victor was decided in 1994, the “firmly convinced” standard
    has achieved extensive recognition and is likely the formulation of the
    reasonable doubt standard most widely approved by American jurists,
    academics, and litigants. Lawrence M. Solan, Refocusing the Burden of
    Proof in Criminal Cases: Some Doubt About Reasonable Doubt, 
    78 Tex. L
    .
    Rev. 105, 145 (1999) (“The superiority of the firmly convinced instruction
    comes not from its semantic fidelity to the reasonable doubt standard
    but from its greater success in promoting important values.”); see also
    Jon O. Newman, Beyond “Reasonable Doubt,” 68 N.Y.U. L. Rev. 979,
    990–91 (1993); Irwin A. Horowitz, Reasonable Doubt Instructions, 3
    Psychol. Pub. Pol’y & L. 285, 297–98 (1997) (discussing the superiority of
    the firmly convinced standard as evidenced by statistical analysis); A
    Handbook of Criminal Terms 574 (Bryan A. Garner ed., 2000); Black’s
    Law Dictionary 1380 (9th ed. 2009) (defining reasonable doubt as “the
    doubt that prevents one from being firmly convinced of a defendant’s
    guilt, or the belief that there is a real possibility that a defendant is not
    guilty.”).
    In her concurring opinion in Victor, Justice Ginsburg stoutly
    endorsed a reasonable doubt instruction proposed by the Federal
    Judicial Center,    characterizing it as     “clear, straightforward, and
    accurate.” 511 U.S. at 27, 114 S. Ct. at 1253, 127 L. Ed. 2d at 603
    (Ginsburg, J., concurring in part and concurring in judgment) (quoting
    Federal Judicial Center (FJC), Pattern Criminal Jury Instructions, at 17-
    18 (instruction 21)).     That instruction embraced firmly convinced
    language comparable to that used in the instruction challenged in this
    case: “Proof beyond a reasonable doubt is proof that leaves you firmly
    convinced of the defendant’s guilt. . . . If, based on your consideration of
    the evidence, you are firmly convinced that the defendant is guilty of the
    15
    crime charged, you must find him guilty.”        Id.   Six federal courts of
    appeals have approved the firmly convinced standard, finding that it
    accurately expresses the degree of certainty required to find a defendant
    guilty beyond a reasonable doubt. See, e.g., United States v. Rodriguez,
    
    162 F.3d 135
    , 146 (1st Cir. 1998); United States v. Conway, 
    73 F.3d 975
    ,
    980 (10th Cir. 1995); United States v. Reese, 
    33 F.3d 166
    , 172 (2d Cir.
    1994); United States v. Williams, 
    20 F.3d 125
    , 131–32 (5th Cir. 1994);
    United States v. Taylor, 
    997 F.2d 1551
    , 1555–56 (D.C. Cir. 1993); United
    States v. Velasquez, 
    980 F.2d 1275
    , 1278 (9th Cir. 1992).
    Numerous state courts have also adopted the FJC pattern
    instruction and expressly approved its firmly convinced language. State
    v. Portillo, 
    898 P.2d 970
    , 974 (Ariz. 1995) (adopting the FJC firmly
    convinced standard in all criminal cases); Winegeart v. State, 
    665 N.E.2d 893
    , 902 (Ind. 1996) (approving the FJC firmly convinced standard and
    recommending     its   use   in   Indiana   courts,    “preferably   with   no
    supplementation or embellishment”); State v. Reyes, 
    116 P.3d 305
    , 314
    (Utah 2005) (requiring that Utah trial courts use the FJC instruction); cf.
    Joyner-Pitts v. State, 
    647 A.2d 116
    , 122–23 (Md. Ct. Spec. App. 1994)
    (quoting the FJC “firmly convinced” instruction with approval).
    We find no reversible error in the “firmly convinced” formulation
    used by the district court in this case.     “Firmly” means “steadfastly,”
    “resolutely,” “soundly,” “solidly,” and “strongly.”         Webster’s Third
    International Dictionary 856 (unabr. ed. 2002). Likewise, “firm” is defined
    as “immovable,” “fixed,” “settled,” “not easily moved, shaken, excited, or
    disturbed.” Id. The word “firmly” is not arcane or obscure, but rather is
    a plain, well-understood word commonly used in modern speech.               We
    believe it adequately expressed—within the due process parameters
    articulated in Victor—the extent of certitude the jury must possess to
    16
    convict a defendant of a crime in this state.7 Accordingly, we conclude
    the district court did not err when it instructed the jury on reasonable
    doubt.
    C. Burden of Proof on Insanity Defense. Frei proposed a jury
    instruction allocating to the State the burden of proving Frei was not
    insane at the time of Bailey’s death. Arguing in favor of the proposed
    jury instruction and in opposition to the instruction actually given by the
    district court in this case, Frei’s counsel made the following record:
    I know the court’s concerned about the fact that we placed
    insanity as an element the State has to disprove, and I think
    due process has to prove that notwithstanding the
    legislature to turn that upside down with the burden on the
    Defendant. But if the court believes that the legislature has
    that power, but we would propose that that be removed from
    the marshaling instructions that that would be the proper
    instruction that should be given.
    Frei argues on appeal that the district court’s allocation to her of
    the burden of proving insanity violated her right to equal protection of
    the law. However, the State contends error was not preserved because
    Frei raised no equal protection argument in the district court.                  Frei
    responds that she raised “constitutional” concerns to the court and
    raised a specific equal protection challenge in her motion for a new trial.
    As we have noted, the record made by Frei’s counsel on the jury
    instructions advanced only a due process argument, not the equal
    protection argument she now asserts. Issues raised for the first time in
    posttrial motions are not sufficient to preserve error. State v. Stone, 764
    7Our  determination that the district court did not err in using the “firmly
    convinced” formulation to define the reasonable doubt standard in this case should not
    be viewed as a rejection of any other formulation expressing in equivalent terms the
    state’s burden of proof.
    
    17 N.W.2d 545
    , 550 (Iowa 2009).        Accordingly, this issue has not been
    preserved for our review.
    D.    Denial of Motion for Mistrial.     When Frei first spoke with
    police, she told them she believed Bailey had died during a drug deal.
    She told them two men had come to the house to conduct a drug
    transaction, that she heard Bailey use racial slurs referring to one of the
    men, and that she heard one of the men speak with an accent she did
    not recognize.
    Frei moved in limine to exclude any reference at trial to the fact
    that she used racial slurs in reporting the story to the police or to the
    fact that she had claimed the fictitious drug dealers belonged to any
    particular racial or ethnic group. The court granted the motion, ruling
    that the State should not reveal to the jury any racial or ethnic slurs
    spoken by Frei, but that “the State may refer to the Defendant
    attempting to blame other persons without reference to ethnic or racial
    characteristics.”
    During opening statements, the prosecution twice referred to the
    defendant    blaming   “Hispanic”    drug   dealers   for   Bailey’s   death.
    Specifically the prosecutor told the jurors that Frei “not only . . . said it
    was a drug deal gone bad, she seemed to blame it on the drug dealers, at
    least one sounded like he was Hispanic.”         The prosecutor’s opening
    statement also asserted that after Frei’s original plan failed and Bailey
    was beaten to death, “then the plan became let’s blame Hispanic drug
    dealers for [Bailey’s] death.” Frei moved for a mistrial.
    The district court inquired of the prosecutor during the ensuing
    colloquy on the motion for mistrial whether it was really worth it to him
    to try to correct the error and run the risk of having any guilty verdict
    overturned on appeal. After hearing the arguments of counsel, the court
    18
    concluded the prosecutor’s statements had violated the order in limine
    but denied the motion “somewhat reluctantly.”        The parties discussed
    whether a curative instruction should be given, but the district court
    declined to give one. When the trial resumed, the prosecutor made the
    following statement to the jury:
    During opening statement there was a reference made the
    Defendant blamed others for a drug deal, and Hispanics. It
    should have just been Defendant blamed others. I was
    incorrect in Hispanics. It was Defendant blamed others.
    Frei contends the district court abused its discretion in denying
    her motion for mistrial. As it is in the best position to appraise the effect
    of any alleged misconduct, we allow the district court broad discretion in
    deciding whether to grant a mistrial. Fry v. Blauvelt, 
    818 N.W.2d 123
    ,
    132 (Iowa 2012). To establish reversible error on this issue, Frei must
    show the violation of the limine order resulted in prejudice that deprived
    her of a fair trial. State v. Greene, 
    592 N.W.2d 24
    , 32 (Iowa 1999). “The
    party claiming prejudice bears the burden of establishing it.”      State v.
    Anderson, 
    448 N.W.2d 32
    , 33 (Iowa 1989).
    Frei contends opening statements strongly influence jurors’
    impressions of the case even before they hear evidence. Noting that her
    justification defense depended on the jury’s perception of her credibility,
    Frei posits that the prosecutor’s disclosure during his opening statement
    of Frei’s false initial report of the incident blaming Hispanics for the
    murder was especially prejudicial.     Upon our review of the record, we
    conclude the prosecution’s remarks and subsequent correction of them
    did not produce such prejudice as would deny Frei a fair trial.          We
    acknowledge the importance of opening statements in the trial process
    and do not diminish the importance of faithful observance of limine
    orders by prosecutors. However, the prosecutor’s attribution to Frei of
    19
    statements blaming Hispanics for the murder and his later attempt to
    “correct” his error did not include racial slurs or other inflammatory
    language.   There were no further violations of the court’s limine order
    during the remainder of the trial.       On this record, we conclude the
    prosecutor’s statements did not deprive Frei of a fair trial. Accordingly,
    the district court did not abuse its discretion in denying Frei’s motion for
    mistrial and we therefore affirm on this issue.
    IV. Conclusion.
    For the reasons stated above, we affirm Frei’s conviction.
    AFFIRMED.
