Question 1 of 5
This drug blocks both beta receptors and K+ channels.
Correct Answer: B
Rationale: The correct answer is B: Sotalol. Sotalol is a non-selective beta-blocker and a class III antiarrhythmic agent that blocks both beta receptors and potassium (K+) channels. By blocking beta receptors, it decreases heart rate and contractility. Blocking K+ channels prolongs the action potential duration, aiding in the treatment of various arrhythmias. Quinidine (A) is a class I antiarrhythmic that primarily blocks Na+ channels. Propranolol (C) is a selective beta-blocker that does not affect K+ channels. Digoxin (D) is a cardiac glycoside that inhibits the sodium-potassium pump but does not block beta receptors or K+ channels.
