Question 1

ACE inhibitors are contraindicated in patients with which condition?

Accepted Answer

Bilateral renal artery stenosis

Answer

ACE inhibitors are contraindicated in bilateral renal artery stenosis because they can cause acute renal failure by reducing glomerular filtration pressure.

Question 2

Which diuretic is most effective for reducing fluid overload in acute decompensated heart failure?

Accepted Answer

Furosemide

Answer

Furosemide, a loop diuretic, is the most effective agent for rapid fluid removal in acute decompensated heart failure due to its potent natriuretic effect.

Question 3

Digoxin toxicity is potentiated by which electrolyte imbalance?

Accepted Answer

Hypokalemia

Answer

Hypokalemia increases digoxin binding to Na+/K+ ATPase, potentiating toxicity and increasing the risk of life-threatening arrhythmias.

Question 4

Amiodarone is classified as a Class III antiarrhythmic because it primarily works by:

Accepted Answer

Blocking potassium channels to prolong repolarization

Answer

Amiodarone blocks potassium channels, prolonging the action potential duration and refractory period, which is the hallmark of Class III antiarrhythmic action.

Question 5

Which medication should be immediately available when administering adenosine for SVT conversion?

Accepted Answer

Atropine

Answer

Atropine should be available when giving adenosine because it can cause prolonged asystole; atropine can be used to restore heart rate if needed.
