Which of the following diuretics can be administered to a patient with edema?

Furosemide is a loop diuretic that is commonly used to treat edema, especially in patients with conditions such as heart failure, renal impairment, or liver disease. It works by inhibiting the sodium-potassium-chloride co-transporter in the ascending loop of Henle in the kidneys, which leads to increased urine output and reduction of excess fluid in the body. This mechanism makes furosemide particularly effective for managing edema, as it helps remove excess fluid from the tissues and cardiovascular system.

In contrast, other options do not have a primary role in the treatment of edema. Amiodarone is an antiarrhythmic medication used for the treatment of various types of cardiac arrhythmias, but it does not have diuretic properties. Hydrochlorothiazide is a thiazide diuretic that can help with fluid retention but is generally less effective than loop diuretics like furosemide when it comes to significant edema. Metoprolol is a beta-blocker used primarily for managing hypertension and heart conditions, rather than for fluid management.

Thus, furosemide is the most appropriate choice for addressing edema due to its potent diuretic action.
