1. A patient with newly diagnosed hypertension has no compelling
comorbidities. Which medication is generally considered an
appropriate first-line option?
A. Clonidine
B. Hydrochlorothiazide
C. Propranolol
D. Digoxin
Answer: B. Hydrochlorothiazide
Rationale: Thiazide-type diuretics are established first-line
antihypertensive agents. They reduce sodium and water retention
and, with continued use, lower systemic vascular resistance. Beta
blockers and centrally acting agents are generally not preferred as
routine first-line therapy without a specific indication.
2. A patient taking an ACE inhibitor develops a persistent dry cough.
Which medication would be an appropriate alternative?
A. Losartan
B. Aliskiren
C. Propranolol
D. Furosemide
1|Page
,Answer: A. Losartan
Rationale: Losartan is an angiotensin II receptor blocker (ARB) and
does not inhibit bradykinin breakdown, making cough substantially
less common than with ACE inhibitors. ARBs are commonly used when
an ACE inhibitor is not tolerated because of cough.
3. Which adverse effect is particularly associated with ACE inhibitors?
A. Hypoglycemia
B. Dry cough and angioedema
C. Ototoxicity
D. Severe constipation
Answer: B. Dry cough and angioedema
Rationale: ACE inhibitors decrease degradation of bradykinin,
contributing to the characteristic persistent cough and, in some
patients, angioedema. Hyperkalemia and increased serum creatinine
can also occur.
4. A patient with heart failure with reduced ejection fraction is
prescribed carvedilol. What is the primary therapeutic benefit of this
medication?
A. Directly increases myocardial oxygen consumption
B. Reduces sympathetic stimulation and improves long-term cardiac
outcomes
C. Produces rapid diuresis
D. Increases sodium retention
Answer: B. Reduces sympathetic stimulation and improves long-term
cardiac outcomes
2|Page
,Rationale: Evidence-based beta blockers such as carvedilol reduce
sympathetic activity, decrease adverse ventricular remodeling, and
improve morbidity and mortality in appropriately selected patients
with HFrEF. They should generally be initiated at low doses when the
patient is clinically stable.
5. Which medication provides rapid symptomatic relief of acute
angina?
A. Nitroglycerin sublingual tablet
B. Atorvastatin
C. Metoprolol extended release
D. Aspirin
Answer: A. Nitroglycerin sublingual tablet
Rationale: Sublingual nitroglycerin rapidly increases nitric oxide
availability, producing venodilation and reducing cardiac preload and
myocardial oxygen demand. It is used for prompt relief of an acute
anginal episode.
6. Which medication should generally not be combined with nitrates
because of the risk of profound hypotension?
A. Acetaminophen
B. Sildenafil
C. Amoxicillin
D. Metformin
Answer: B. Sildenafil
3|Page
, Rationale: Sildenafil and other phosphodiesterase-5 inhibitors
potentiate nitric oxide-mediated vasodilation. Combining them with
nitrates can cause severe, potentially life-threatening hypotension.
7. A patient with hyperlipidemia is prescribed atorvastatin. Which
laboratory parameter is particularly relevant for monitoring potential
hepatic effects?
A. ALT and AST
B. Serum amylase only
C. Hemoglobin A1c only
D. Serum sodium only
Answer: A. ALT and AST
Rationale: Statins can cause elevations in hepatic transaminases. Liver
enzymes may be assessed when clinically indicated, particularly when
symptoms suggest hepatic injury. Statins can also rarely cause
significant muscle toxicity.
8. A patient taking a statin reports severe unexplained muscle pain
and weakness. What complication should be considered?
A. Rhabdomyolysis
B. Agranulocytosis
C. Pulmonary fibrosis
D. Hyperthyroidism
Answer: A. Rhabdomyolysis
Rationale: Severe muscle symptoms, particularly when accompanied
by marked creatine kinase elevation or dark urine, may indicate
