Question 1
A drug with a high first-pass effect is administered orally. Where is it primarily
metabolized before reaching systemic circulation?
A. Kidneys
B. Lungs
C. Liver
D. Stomach
Correct ,,answer,,,: C
Rationale: First-pass metabolism occurs in the liver (C). Kidneys (A) excrete
drugs. Lungs (B) metabolize some drugs but not primary first-pass. Stomach (D)
absorbs but does not significantly metabolize.
,Question 2
A patient receives a drug with a half-life of 4 hours. Approximately how many
hours will it take to reach steady state?
A. 8 hours
B. 12 hours
C. 20 hours
D. 40 hours
Correct ,,answer,,,: C
Rationale: Steady state is reached in 4–5 half-lives (20 hours for 5 half-lives). 8
hours (A) is 2 half-lives. 12 hours (B) is 3 half-lives. 40 hours (D) is 10 half-lives.
Question 3
A beta-1 selective antagonist is prescribed for a patient with hypertension. Which
effect is most expected?
A. Bronchospasm
B. Decreased heart rate
C. Peripheral vasodilation
D. Increased cardiac contractility
Correct ,,answer,,,: B
Rationale: Beta-1 blockade decreases heart rate (B) and contractility.
Bronchospasm (A) from beta-2 blockade. Peripheral vasodilation (C) from alpha
blockade. Increased contractility (D) opposite.
,Question 4
A patient taking warfarin has an INR of 4.5 without bleeding. Which action is most
appropriate?
A. Administer vitamin K
B. Hold the next dose and recheck INR
C. Increase the warfarin dose
D. Administer fresh frozen plasma
Correct ,,answer,,,: B
Rationale: INR 4.5 without bleeding → hold dose (B) and recheck. Vitamin K (A)
for INR >10 or bleeding. Increase (C) worsens. FFP (D) for active bleeding.
Question 5
A patient is prescribed digoxin for heart failure. Which electrolyte abnormality
increases the risk of digoxin toxicity?
A. Hypernatremia
B. Hypokalemia
C. Hypercalcemia
D. Hypermagnesemia
Correct ,,answer,,,: B
Rationale: Hypokalemia (B) increases digoxin binding to Na/K-ATPase →
toxicity. Hypernatremia (A) not directly. Hypercalcemia (C) also increases toxicity
but hypokalemia is more common. Hypermagnesemia (D) decreases risk.
, Question 6
A patient with type 2 diabetes is started on metformin. Which adverse effect is
most common?
A. Hypoglycemia
B. Weight gain
C. Lactic acidosis
D. Gastrointestinal distress
Correct ,,answer,,,: D
Rationale: GI distress (D) is most common (nausea, diarrhea). Hypoglycemia (A)
rare with metformin alone. Weight gain (B) is associated with
sulfonylureas/insulin. Lactic acidosis (C) rare but serious.
Question 7
A patient is prescribed a loop diuretic for heart failure. Which electrolyte
imbalance is most concerning?
A. Hypernatremia
B. Hypokalemia
C. Hypermagnesemia
D. Hypercalcemia
Correct ,,answer,,,: B
Rationale: Loop diuretics cause hypokalemia (B) due to increased distal delivery
of sodium and water. Hypernatremia (A) not typical. Hypermagnesemia (C)
opposite. Hypercalcemia (D) not from loop diuretics (thiazides cause
hypercalcemia).
