Practice Questions
1. A 75-year-old patient with heart failure and hypoalbuminemia is prescribed a
highly protein-bound drug. The NP anticipates which pharmacokinetic change?
A. Decreased volume of distribution
B. Increased free drug concentration and risk of toxicity
C. Decreased drug half-life
D. Increased first-pass metabolism
Answer: B
Expert Rationale: Hypoalbuminemia reduces protein binding sites, increasing the
fraction of free (active) drug. Combined with age-related renal decline, this
significantly increases toxicity risk.
2. A patient is a CYP2D6 poor metabolizer. Which medication would have
reduced efficacy due to impaired activation?
A. Omeprazole
B. Codeine
C. Diazepam
D. Propranolol
Answer: B
Expert Rationale: Codeine is a prodrug requiring CYP2D6-mediated conversion
to its active metabolite, morphine. Poor metabolizers have reduced conversion,
leading to inadequate analgesia.
