SECTION 1: CARDIOVASCULAR PHARMACOLOGY - Questions 1-8
Q1: Antihypertensives - ACE Inhibitors
ACE inhibitors (lisinopril) work by:
A. Blocking calcium channels
B. Blocking angiotensin-converting enzyme
C. Blocking beta-receptors
D. Blocking alpha-receptors
Correct Answer: B
Rationale: ACE inhibitors block the conversion of angiotensin I to angiotensin II, reducing
vasoconstriction and aldosterone secretion. This lowers blood pressure. [100% CORRECT]
Q2: ACE Inhibitors - Side Effects
A common side effect of ACE inhibitors is:
A. Dry cough
B. Hyperkalemia
C. Angioedema
D. All of the above
Correct Answer: D
Rationale: ACE inhibitors commonly cause dry cough (bradykinin accumulation), hyperkalemia
(reduced aldosterone), and angioedema (rare but serious). [100% CORRECT]
Q3: ARBs - Mechanism
ARBs (losartan) work by:
A. Blocking ACE
B. Blocking the angiotensin II receptor
C. Blocking calcium channels
D. Blocking beta-receptors
Correct Answer: B
Rationale: ARBs block the angiotensin II receptor, preventing vasoconstriction and aldosterone
release. They are an alternative to ACE inhibitors, especially if cough occurs. [100% CORRECT]
Q4: Calcium Channel Blockers - Indications
Calcium channel blockers (amlodipine) are used for:
A. Hypertension and angina
, 2
B. Heart failure only
C. Arrhythmias only
D. Asthma
Correct Answer: A
Rationale: Calcium channel blockers are used for hypertension, angina, and some arrhythmias.
Dihydropyridines (amlodipine) are primarily for hypertension and angina. [100% CORRECT]
Q5: Beta-Blockers - Indications
Beta-blockers (metoprolol) are used for:
A. Hypertension, angina, and heart failure
B. Asthma
C. COPD
D. Raynaud's
Correct Answer: A
Rationale: Beta-blockers are used for hypertension, angina, heart failure, arrhythmias, and migraine
prophylaxis. They are contraindicated in asthma and COPD due to bronchospasm risk. [100%
CORRECT]
Q6: Beta-Blockers - Contraindications
Beta-blockers should be used cautiously or avoided in patients with:
A. Hypertension
B. Heart failure
C. Asthma or COPD
D. Angina
Correct Answer: C
Rationale: Non-selective beta-blockers are contraindicated in asthma due to bronchospasm.
Cardioselective beta-blockers (metoprolol) may be used cautiously in COPD. [100% CORRECT]
Q7: Statins - Mechanism
Statins (atorvastatin) work by:
A. Inhibiting cholesterol absorption
B. Inhibiting HMG-CoA reductase
C. Increasing bile acid excretion
D. Blocking cholesterol synthesis
Correct Answer: B
Rationale: Statins inhibit HMG-CoA reductase, the rate-limiting enzyme in cholesterol synthesis. This
lowers LDL cholesterol. [100% CORRECT]
Q8: Statins - Side Effects
A common side effect of statins is:
A. Muscle pain (myalgia)
