CFPN General 2 — Questions and Answers
Question 1: When a forensic pharmacy nurse is asked to testify as an expert witness, which standard governs the admissibility of their scientific testimony in federal court?
- Frye standard
- Daubert standard (Correct answer)
- Kumho standard
- Federal Rule 702 only
Correct answer: Daubert standard
The Daubert standard, established in Daubert v. Merrell Dow Pharmaceuticals (1993), is the federal court standard for admissibility of expert scientific testimony.
Question 2: A patient presents with miosis, bradycardia, excessive salivation, and bronchospasm. Which toxidrome does this presentation best represent?
- Sympathomimetic
- Anticholinergic
- Cholinergic (Correct answer)
- Sedative-hypnotic
Correct answer: Cholinergic
The cholinergic toxidrome (SLUDGE/DUMBELS) is characterized by miosis, bradycardia, salivation, and bronchospasm due to excess acetylcholine activity.
Question 3: In the context of drug-facilitated crimes, what is the typical detection window for GHB in urine?
- 24–48 hours
- 72–96 hours
- 4–8 hours (Correct answer)
- 1–2 weeks
Correct answer: 4–8 hours
GHB is rapidly metabolized and typically detectable in urine for only 4–8 hours after ingestion, making timely specimen collection critical.
Question 4: Which agency maintains the National Forensic Laboratory Information System (NFLIS) in the United States?
- FDA
- DEA (Correct answer)
- CDC
- NIDA
Correct answer: DEA
The DEA maintains NFLIS, which collects and disseminates drug identification data from federal, state, and local forensic laboratories.
Question 5: A forensic pharmacy nurse reviewing a medical record notes that a patient received a higher-than-prescribed opioid dose. The FIRST priority in documenting this finding is to:
- Notify law enforcement immediately
- Ensure chain of custody for records is maintained (Correct answer)
- Administer naloxone prophylactically
- Contact the prescribing physician for clarification
Correct answer: Ensure chain of custody for records is maintained
Maintaining chain of custody for medical records ensures the integrity of evidence and is the foundational first step in any forensic documentation process.
Question 6: Which pharmacokinetic parameter is most important when interpreting postmortem drug concentrations?
- Half-life
- Volume of distribution
- Postmortem redistribution (Correct answer)
- Protein binding
Correct answer: Postmortem redistribution
Postmortem redistribution causes drug concentrations to change after death as drugs migrate from tissue depots, making antemortem concentration estimates unreliable.
Question 7: Under HIPAA, which of the following represents a permissible disclosure of protected health information without patient authorization in a forensic context?
- Disclosure to a patient's employer upon request
- Disclosure required by court order or subpoena (Correct answer)
- Disclosure to family members for general care coordination
- Disclosure for marketing purposes by a covered entity
Correct answer: Disclosure required by court order or subpoena
HIPAA permits disclosure of PHI without patient authorization when required by a court order, subpoena, or other legal process.
