CFPN General 3 — Questions and Answers
Question 1: A forensic pharmacy nurse is evaluating a suspected drug-facilitated sexual assault case. Which specimen, if available, provides the longest detection window for most drugs?
- Blood
- Urine
- Hair (Correct answer)
- Saliva
Correct answer: Hair
Hair analysis can detect drug use for weeks to months after ingestion, providing the longest detection window and is valuable when other specimens are no longer useful.
Question 2: Which Schedule under the Controlled Substances Act includes drugs with accepted medical use but a high potential for abuse and severe psychological or physical dependence?
- Schedule I
- Schedule II (Correct answer)
- Schedule III
- Schedule IV
Correct answer: Schedule II
Schedule II drugs (e.g., morphine, oxycodone, fentanyl) have accepted medical uses but the highest potential for abuse among drugs with accepted medical use.
Question 3: When collecting urine for forensic drug testing, which technique best prevents specimen adulteration?
- Allowing unsupervised collection in a standard restroom
- Using a split specimen collection protocol with temperature verification (Correct answer)
- Storing specimens at room temperature for 24 hours before testing
- Performing only immunoassay screening without confirmation
Correct answer: Using a split specimen collection protocol with temperature verification
Split specimen collection combined with immediate temperature verification (32–38°C) helps ensure specimen validity and detects adulteration or substitution.
Question 4: The concept of 'therapeutic privilege' in forensic pharmacy practice refers to:
- A nurse's right to refuse to testify against a patient
- Withholding information from a patient when disclosure may cause harm (Correct answer)
- Privilege to administer controlled substances without a prescription in emergencies
- Protection of communications between nurse and attorney
Correct answer: Withholding information from a patient when disclosure may cause harm
Therapeutic privilege allows clinicians to withhold information from a patient if full disclosure would cause significant psychological or physical harm, though it is ethically controversial.
Question 5: Which analytical method is considered the gold standard for confirming positive immunoassay drug screen results in forensic toxicology?
- Enzyme-linked immunosorbent assay (ELISA)
- Gas chromatography-mass spectrometry (GC-MS) (Correct answer)
- Thin-layer chromatography (TLC)
- High-performance liquid chromatography (HPLC) alone
Correct answer: Gas chromatography-mass spectrometry (GC-MS)
GC-MS is the confirmatory gold standard because it identifies drugs by both chromatographic retention time and mass spectral fragmentation pattern, providing definitive identification.
Question 6: A forensic pharmacy nurse is reviewing a case of suspected elder financial abuse linked to medication changes. Which drug class, when inappropriately prescribed, is most commonly associated with inducing vulnerability in elderly victims?
- Antibiotics
- Benzodiazepines (Correct answer)
- Statins
- Antihypertensives
Correct answer: Benzodiazepines
Benzodiazepines cause sedation, cognitive impairment, and disinhibition in the elderly, making them particularly vulnerable to exploitation when overprescribed.
Question 7: In forensic pharmacy, 'pill mill' investigations typically focus on prescribers who:
- Prescribe exclusively generic medications to reduce costs
- Issue controlled substance prescriptions outside the usual course of professional practice (Correct answer)
- Specialize in pain management using only non-opioid therapies
- Report all controlled substance prescriptions to state PDMPs voluntarily
Correct answer: Issue controlled substance prescriptions outside the usual course of professional practice
Pill mills are characterized by prescribers who issue controlled substance prescriptions for illegitimate purposes, without proper medical evaluation or documentation.
