- A. Chewable aspirin
- B. Oral warfarin
- C. Intramuscular vitamin K
- D. Slow-release nifedipine
Explanation: Chewable aspirin reduces platelet aggregation and helps limit coronary thrombus formation during suspected acute coronary syndrome.
Correct answer: Chewable aspirin- A. Holosystolic murmur radiating to the axilla
- B. Harsh ejection murmur radiating to the neck
- C. Mid-diastolic murmur with opening snap
- D. Continuous machinery murmur below the clavicle
Explanation: Mitral regurgitation commonly produces a holosystolic murmur that radiates toward the left axilla because blood flows back into the left…
Correct answer: Holosystolic murmur radiating to the axilla- A. Complete heart block
- B. First-degree heart block
- C. Sinus bradycardia
- D. Atrial fibrillation
Explanation: Complete heart block causes atrioventricular dissociation, so the atria and ventricles beat independently.
Correct answer: Complete heart block- A. Sitting upright and leaning forward
- B. Lying flat with legs elevated
- C. Right lateral position with knees flexed
- D. Trendelenburg position with the head low
Explanation: Sitting upright and leaning forward often decreases the inflamed pericardial surfaces rubbing against each other and may relieve pain.
Correct answer: Sitting upright and leaning forward- A. It supports ventricular strain and heart failure
- B. It confirms an acute bacterial endocarditis
- C. It indicates severe liver failure
- D. It proves the patient has pulmonary embolism
Explanation: B-type natriuretic peptide is released when the ventricles are stretched, so an increased level supports ventricular strain and heart…
Correct answer: It supports ventricular strain and heart failure- A. Synchronized electrical cardioversion
- B. Routine oral potassium replacement
- C. Unscheduled exercise testing
- D. Slow infusion of oral digoxin only
Explanation: Hypotension and chest pain indicate haemodynamic instability, so synchronized cardioversion is the priority treatment for unstable atrial…
Correct answer: Synchronized electrical cardioversion- A. Serum potassium 2.9 mmol/L
- B. Serum sodium 140 mmol/L
- C. Serum calcium 2.3 mmol/L
- D. Serum chloride 102 mmol/L
Explanation: Hydrochlorothiazide can increase urinary potassium loss, and hypokalaemia can cause weakness, cramps and dysrhythmias.
Correct answer: Serum potassium 2.9 mmol/L- A. Plan rest periods between activities
- B. Avoid all physical activity permanently
- C. Take extra doses of medicine before exertion
- D. Complete strenuous tasks immediately after meals
Explanation: Planned rest periods reduce oxygen demand and help prevent fatigue and exertional chest discomfort.
Correct answer: Plan rest periods between activities- A. Cardiac tamponade
- B. Left ventricular hypertrophy
- C. Chronic venous insufficiency
- D. Stable exertional angina
Explanation: Hypotension, jugular venous distention and muffled heart sounds are classic features of cardiac tamponade caused by pressure from fluid…
Correct answer: Cardiac tamponade- A. Ankle oedema
- B. Severe hypoglycaemia
- C. Green-yellow visual halos
- D. Persistent dry cough
Explanation: Amlodipine, a calcium channel blocker, commonly causes peripheral ankle oedema from arteriolar vasodilation.
Correct answer: Ankle oedema
