CFN Legal Testimony & Expert Witness Responsibilities 4 — Questions and Answers
Question 1: A forensic nurse is asked during testimony to render an opinion 'to a reasonable degree of medical certainty.' What does this standard require?
- Absolute scientific certainty with no margin of error
- A probability greater than 50% that the opinion is more likely true than not (Correct answer)
- Unanimity among all forensic nurses who reviewed the case
- Documented agreement from at least three peer-reviewed sources
Correct answer: A probability greater than 50% that the opinion is more likely true than not
Reasonable medical certainty means the expert believes the opinion is more probably true than not, which is a preponderance standard, not absolute certainty.
Question 2: A forensic nurse expert is contacted directly by the opposing party's attorney without her retaining attorney's knowledge. What should she do?
- Speak freely since all communications in litigation must be transparent
- Decline to speak with opposing counsel without her retaining attorney present or consenting (Correct answer)
- Provide only her written report and refuse to say anything further
- Report the contact to the judge immediately
Correct answer: Decline to speak with opposing counsel without her retaining attorney present or consenting
An expert should not communicate with opposing counsel ex parte without the retaining attorney's knowledge or consent to avoid ethical complications.
Question 3: Which factor is LEAST relevant when determining whether a forensic nurse qualifies as an expert witness?
- Clinical experience in forensic nursing
- Academic publications in forensic science journals
- The number of years since she graduated nursing school (Correct answer)
- Board certification in forensic nursing
Correct answer: The number of years since she graduated nursing school
Years since graduation alone does not establish expertise; relevant qualifications include specialized training, certification, clinical experience, and scholarship.
Question 4: During testimony, defense counsel produces a prior article authored by the forensic nurse expert that appears to contradict her current opinion. This is an example of:
- Rehabilitation
- Prior consistent statement
- Impeachment by prior inconsistent statement (Correct answer)
- Judicial notice
Correct answer: Impeachment by prior inconsistent statement
Using the expert's own prior written statements to challenge her current trial testimony is a classic impeachment technique via prior inconsistent statement.
Question 5: A forensic nurse is retained as a consulting expert but not disclosed as a testifying expert. Which statement best describes her role?
- She may testify if the retaining attorney decides she is needed at the last minute
- Her identity and opinions may remain confidential and protected as attorney work product (Correct answer)
- She must be disclosed to opposing counsel regardless of whether she testifies
- She can prepare the testifying expert's report on behalf of the attorney
Correct answer: Her identity and opinions may remain confidential and protected as attorney work product
Non-testifying consulting experts are generally protected from discovery as attorney work product unless extraordinary circumstances exist.
Question 6: When a forensic nurse testifies about strangulation findings, she notes petechial hemorrhages in the victim's conjunctivae. If opposing counsel asks whether these can occur from causes other than strangulation, the best response is:
- 'No, petechiae are definitive proof of strangulation.'
- 'Yes, petechiae can result from other causes such as vomiting or severe coughing, but the pattern here is consistent with strangulation.' (Correct answer)
- 'I cannot answer that question without reviewing additional studies.'
- 'That question is outside my area of expertise.'
Correct answer: 'Yes, petechiae can result from other causes such as vomiting or severe coughing, but the pattern here is consistent with strangulation.'
Acknowledging alternative causes while explaining why the clinical pattern supports the primary opinion demonstrates objectivity and strengthens credibility.
Question 7: Which document is an expert witness typically required to produce during discovery under Federal Rules of Civil Procedure Rule 26?
- A list of all cases in which the expert has testified in any capacity in the prior four years (Correct answer)
- All clinical records from every patient the expert has treated in the past decade
- The expert's complete income tax returns for verification of fee claims
- Confidential communications between the expert and retaining counsel
Correct answer: A list of all cases in which the expert has testified in any capacity in the prior four years
FRCP Rule 26(a)(2)(B) requires expert disclosure to include a list of cases in which the expert has testified at deposition or trial in the prior four years.
