Question 1

Which medication class is first-line for managing symptomatic heart failure with reduced ejection fraction (HFrEF)?

Accepted Answer

ACE inhibitors or ARBs plus beta-blockers

Answer

Calcium channel blockers

Answer

Loop diuretics alone

Answer

Digoxin alone

Question 2

Adenosine is used in cardiac stress testing primarily because it:

Accepted Answer

Causes coronary vasodilation, revealing perfusion differences

Answer

Increases heart rate and blood pressure

Answer

Stabilizes atrial fibrillation

Answer

Reverses beta-blocker effects

Question 3

Anticoagulation with warfarin requires monitoring via:

Accepted Answer

INR (International Normalized Ratio)

Answer

aPTT (activated partial thromboplastin time)

Answer

Anti-Xa levels

Answer

Platelet count

Question 4

Beta-blockers are contraindicated in acute decompensated heart failure because they:

Accepted Answer

Reduce the heart's ability to compensate via increased heart rate

Answer

Increase systemic vascular resistance

Answer

Cause hyperkalemia

Answer

Induce torsades de pointes

Question 5

Heparin anticoagulation during cardiac catheterization is monitored with:

Accepted Answer

Activated clotting time (ACT)

Answer

INR

Answer

Anti-Xa level

Answer

Thrombin time

Question 6

Nitroglycerin reduces cardiac workload primarily by:

Accepted Answer

Decreasing preload through venodilation

Answer

Increasing heart rate

Answer

Blocking beta-adrenergic receptors

Answer

Increasing myocardial contractility
