The symptoms and history are consistent with heart failure. The question is asking about which medication is most likely part of his treatment regimen.Choice A, Ibutilide, is an antiarrhythmic drug used to treat atrial fibrillation and flutter. It does not have a role in treating heart failure. Choice B, Lidocaine, is a local anesthetic and antiarrhythmic drug. It also does not have a role in treating heart failure.Choice C, Aspirin, is an antiplatelet drug used to prevent blood clots. It may be used as secondary prevention in some heart failure patients, but is not a first-line treatment.Choice D, Carvedilol, is a beta-blocker used to treat heart failure and hypertension. Beta-blockers like carvedilol are a cornerstone of heart failure treatment by blocking catecholamines and decreasing myocardial oxygen demand. Choice E, Verapamil, is a calcium channel blocker used to treat hypertension, angina, and arrhythmias.
