, 300 Exam-Style Questions with Verified Answers and
Rationales
Qn 1. A patient is receiving a drug that is a substrate for CYP3A4. Which of the following drugs
would increase the risk of toxicity by inhibiting this enzyme?
A. A. Rifampin
B. B. Phenytoin
C. C. Carbamazepine
D. D. Ketoconazole
Correct Answer: D. Ketoconazole
Rationale: Ketoconazole is a strong CYP3A4 inhibitor. Inhibition of CYP3A4 can increase serum
levels of medications that are substrates for this enzyme, leading to potential toxicity.
Understanding CYP450 interactions is essential for safe prescribing.
Why Wrong:
A. A: Rifampin is a CYP3A4 inducer, which reduces drug levels.
B. B: Phenytoin is a CYP3A4 inducer.
C. C: Carbamazepine is a CYP3A4 inducer.

Qn 2. When prescribing medications for a geriatric patient, which of the following
pharmacokinetic changes is most significant?
A. A. Increased renal clearance
B. B. Decreased gastric pH
C. C. Decreased hepatic metabolism
D. D. Increased total body water
Correct Answer: C. Decreased hepatic metabolism
Rationale: Decreased hepatic metabolism is a significant pharmacokinetic change in geriatric
patients due to reduced liver mass and hepatic blood flow. This can lead to increased drug levels
and risk of toxicity. Dose adjustments are often necessary for drugs metabolized by the liver.
Why Wrong:
, A. A: Renal clearance typically decreases with age.
B. B: Gastric pH typically increases with age.
C. D: Total body water decreases with age.

Course Materials; FDA Guidelines.
Qn 3. A patient is prescribed a drug with a high extraction ratio. Which of the following
statements about this drug is true?
A. A. The drug is primarily cleared by the kidneys
B. B. The drug has low bioavailability
C. C. The drug has high hepatic clearance and is affected by liver blood flow
D. D. The drug is highly protein-bound
Correct Answer: C. The drug has high hepatic clearance and is affected by liver blood flow
Rationale: Drugs with a high extraction ratio have high hepatic clearance that is dependent on
liver blood flow. Changes in hepatic blood flow can significantly affect the clearance of these drugs.
This is an important consideration for drugs with extensive first-pass metabolism.
Why Wrong:
A. A: High extraction ratio is typically associated with hepatic clearance, not renal.
B. B: Bioavailability is affected by first-pass metabolism but is not the primary characteristic.
C. D: Protein binding is not directly related to the extraction ratio.

Qn 4. A patient with type 2 diabetes is prescribed metformin. Which of the following is the
primary mechanism of action of metformin?
A. A. Stimulation of insulin secretion
B. B. Decreased hepatic glucose production
C. C. Slowing of carbohydrate absorption
D. D. Enhancement of insulin sensitivity
Correct Answer: B. Decreased hepatic glucose production
Rationale: Metformin decreases hepatic glucose production (gluconeogenesis) and increases
peripheral insulin sensitivity. It does not stimulate insulin secretion, which makes it less likely to
cause hypoglycemia. This is the primary mechanism of metformin.
