CFPN General 5 — Questions and Answers
Question 1: In a drug-facilitated assault case, the forensic pharmacy nurse is asked about the pharmacodynamic effects of flunitrazepam (Rohypnol). Which effect is most clinically relevant to victim vulnerability?
- Hypertension and tachycardia
- Anterograde amnesia and sedation (Correct answer)
- Hyperalgesia and seizures
- Miosis and diaphoresis
Correct answer: Anterograde amnesia and sedation
Flunitrazepam produces potent anterograde amnesia and sedation, making victims unable to resist assault or recall events, which is why it is classified as a drug-facilitated assault agent.
Question 2: Under the Drug-Free Workplace Act, federally mandated workplace drug testing must use which laboratory standard for specimen testing?
- CLIA-certified laboratory standards
- SAMHSA/HHS Mandatory Guidelines (Correct answer)
- Joint Commission accreditation standards
- State pharmacy board guidelines
Correct answer: SAMHSA/HHS Mandatory Guidelines
The SAMHSA/HHS Mandatory Guidelines for Federal Workplace Drug Testing Programs set the standards for certified laboratory testing, collection procedures, and MRO review.
Question 3: A Medical Review Officer (MRO) reviewing a confirmed positive amphetamine result would consider which finding as a legitimate medical explanation before reporting it to the employer?
- A valid prescription for lisdexamfetamine dimesylate (Correct answer)
- A history of caffeine use
- Self-reported herbal supplement use
- A documented shellfish allergy
Correct answer: A valid prescription for lisdexamfetamine dimesylate
A valid prescription for a Schedule II amphetamine-containing medication (e.g., lisdexamfetamine) provides a legitimate medical explanation that an MRO must consider before reporting a positive result.
Question 4: Which type of error occurs when a forensic toxicology test reports a drug as absent when it is actually present in the specimen?
- False positive
- False negative (Correct answer)
- Type I error
- Analytical interference
Correct answer: False negative
A false negative (missed detection) occurs when a drug is truly present but the test fails to detect it, often due to specimen adulteration, dilution, or test sensitivity limitations.
Question 5: A forensic pharmacy nurse is reviewing a case involving a nurse anesthetist suspected of diverting propofol. What makes propofol diversion particularly dangerous and challenging to detect?
- Propofol is water-soluble and rapidly excreted, with no standard urine test (Correct answer)
- Propofol is a Schedule II controlled substance with strict DEA tracking
- Propofol causes a distinctive odor easily detected in the work environment
- Propofol diversion always leaves clear electronic health record evidence
Correct answer: Propofol is water-soluble and rapidly excreted, with no standard urine test
Propofol is not a DEA-scheduled drug, has no standard urine immunoassay test, and is rapidly metabolized, making both detection and regulatory oversight difficult.
Question 6: When a forensic pharmacy nurse prepares a written expert opinion for civil litigation, the opinion must be based on:
- Personal intuition and clinical experience alone
- A reasonable degree of pharmaceutical/pharmacological certainty (Correct answer)
- Absolute scientific certainty without any doubt
- Only peer-reviewed studies published within the last 2 years
Correct answer: A reasonable degree of pharmaceutical/pharmacological certainty
Expert opinions in civil litigation must be expressed to a 'reasonable degree of pharmaceutical certainty,' meaning more probable than not, based on sound scientific methodology.
Question 7: A forensic pharmacy nurse notices that a nursing home resident's worsening confusion coincides with the addition of a new anticholinergic medication. This adverse outcome could have been predicted by consulting which tool?
- Beers Criteria
- STOPP/START criteria
- Anticholinergic Cognitive Burden (ACB) scale
- All of the above (Correct answer)
Correct answer: All of the above
The Beers Criteria, STOPP/START criteria, and ACB scale all flag anticholinergic medications as high-risk in elderly patients due to cognitive and functional adverse effects.
In a drug-facilitated assault case, the forensic pharmacy nurse is asked about the pharmacodynamic effects of flunitrazepam (Rohypnol).
