Question 1
A patient with cirrhosis has reduced hepatic blood flow. Which
pharmacokinetic process is most significantly affected for a high-
extraction ratio drug?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
Answer: C) Metabolism
Rationale: High-extraction ratio drugs (e.g., propranolol,
lidocaine) are highly dependent on liver blood flow. Reduced
1
,flow decreases first-pass metabolism, increasing bioavailability
and risk of toxicity.
Question 2
A drug with a half-life of 12 hours is administered intravenously.
Approximately how many hours until steady state is achieved?
A) 24 hours
B) 36 hours
C) 60 hours
D) 120 hours
Answer: C) 60 hours
Rationale: Steady state is reached after 4–5 half-lives. 12 × 5
= 60 hours.
Question 3
Which statement best describes the volume of distribution (Vd) of
a highly lipophilic drug?
A) Low Vd, confined to plasma
2
,B) High Vd, extensive tissue binding
C) Low Vd, high protein binding
D) Equal to total body water
Answer: B) High Vd, extensive tissue binding
Rationale: Lipophilic drugs (e.g., digoxin, amiodarone) distribute
into adipose and tissues, resulting in high Vd (>0.6 L/kg). Low Vd
indicates plasma confinement.
Question 4
A patient is on warfarin. Which drug interaction would most
likely increase INR and bleeding risk?
A) Rifampin
B) Oral contraceptives
C) Vitamin K
D) Metronidazole
Answer: D) Metronidazole
Rationale: Metronidazole inhibits CYP2C9, decreasing warfarin
3
, metabolism → increased INR. Rifampin and OCPs decrease
warfarin effect; vitamin K reverses it.
Question 5
A drug follows zero-order kinetics. Which statement is true?
A) Half-life is constant
B) A constant amount of drug is eliminated per unit time
C) Steady state is reached in 4 half-lives
D) Elimination is proportional to drug concentration
Answer: B) A constant amount of drug is eliminated per unit time
Rationale: Zero-order kinetics (e.g., phenytoin, ethanol, high-
dose aspirin) means saturation of metabolic enzymes. Half-life
increases with dose.
Question 6
A 75-year-old patient receives a standard dose of a renally
cleared medication. Which age-related change increases risk of
toxicity?
4
