Question 1

Amiodarone is effective for treating which arrhythmias?

Accepted Answer

Both atrial and ventricular arrhythmias

Answer

Amiodarone is a broad-spectrum antiarrhythmic (Class III) effective for both atrial arrhythmias (AF, flutter) and ventricular arrhythmias (VT, VF).

Question 2

Which drug class is used to reduce heart rate in atrial fibrillation through AV nodal blockade?

Accepted Answer

Beta-blockers and non-dihydropyridine calcium channel blockers

Answer

Beta-blockers and non-dihydropyridine calcium channel blockers (diltiazem, verapamil) slow AV nodal conduction to achieve ventricular rate control in atrial fibrillation.

Question 3

Aspirin and a P2Y12 inhibitor (dual antiplatelet therapy) are required after coronary stent placement for:

Accepted Answer

At least 6–12 months (drug-eluting stent) to prevent stent thrombosis

Answer

Dual antiplatelet therapy (DAPT) is mandatory for at least 6–12 months after drug-eluting stent placement to prevent stent thrombosis during endothelialization.

Question 4

Dobutamine stress echocardiography uses dobutamine to:

Accepted Answer

Increase heart rate and contractility to simulate exercise stress

Answer

Dobutamine is a beta-1 agonist that increases heart rate and contractility, simulating exercise-like physiologic stress to assess wall motion and viability.

Question 5

Protamine sulfate is used to reverse the effects of:

Accepted Answer

Unfractionated heparin

Answer

Protamine sulfate binds and neutralizes unfractionated heparin; it only partially reverses LMWH and has no effect on DOACs.
