Forosemide (Lasix) is what type of diuretic? a. Potassium-sparing diuretic b. Osmotic diuretic c. Loop diuretic d. Thiazide diuretic

The correct answer is c. Loop diuretic.<br /><br />Furosemide (Lasix) is a loop diuretic. Loop diuretics work by inhibiting the sodium-potassium-chloride cotransporter in the thick ascending limb of the loop of Henle in the kidneys. This leads to increased excretion of sodium, potassium, and chloride, resulting in increased urine output (diuresis). Loop diuretics are commonly used to treat conditions such as edema associated with congestive heart failure, liver disease, and kidney disease, as well as hypertension.
