1. A patient with a history of asthma requires a beta-blocker for hypertension. Which of the
following agents is the most appropriate to minimize the risk of bronchospasm?
A. Propranolol
B. Nadolol
C. Metoprolol
D. Pindolol
Answer: C
Conceptual Explanation: Metoprolol is a cardioselective beta-1 blocker, whereas
Propranolol and Nadolol are non-selective and can block beta-2 receptors in the lungs,
triggering bronchospasm. Pindolol has intrinsic sympathomimetic activity but is still non-
selective.
2. A patient is prescribed Warfarin. Which genetic polymorphism is most likely to result in a
requirement for a significantly lower maintenance dose to avoid bleeding?
A. CYP2D6 *4
,B. CYP3A4 *1
C. CYP2C9 *3
D. CYP1A2 *2
Answer: C
Conceptual Explanation: The CYP2C9 enzyme is responsible for the metabolism of S-
warfarin. Polymorphisms like CYP2C92 and 3 reduce enzyme activity, leading to higher
drug levels and lower dosage requirements.
3. In the management of heart failure, which mechanism explains why Spironolactone
provides a mortality benefit beyond its diuretic effect?
A. Inhibition of the Na+/K+/2Cl- cotransporter
B. Direct vasodilation of the afferent arteriole
C. Antagonism of mineralocorticoid receptors to prevent cardiac fibrosis
D. Activation of the natriuretic peptide system
Answer: C
Conceptual Explanation: Spironolactone blocks aldosterone, which prevents the
maladaptive cardiac remodeling and fibrosis associated with chronic heart failure, leading
to improved survival.
, 4. A 65-year-old patient taking Lisinopril develops a dry, non-productive cough. What is the
biochemical cause of this adverse effect?
A. Increased levels of Angiotensin II
B. Decreased levels of Nitric Oxide
C. Accumulation of bradykinin in the lungs
D. Inhibition of prostaglandins
Answer: C
Conceptual Explanation: ACE inhibitors block the enzyme that breaks down bradykinin.
The resulting accumulation of bradykinin in the respiratory tract leads to the characteristic
dry cough.
5. Which of the following Calcium Channel Blockers (CCBs) is most likely to cause reflex
tachycardia?
A. Verapamil
B. Diltiazem
C. Amlodipine
D. Nifedipine
Answer: D
