A nurse is caring for a client that will receive a diuretic for fluid overload.
Which of the following diuretics act on the loop of Henle?
Spironolactone.
Hydrochlorothiazide.
Furosemide.
Mannitol.
The Correct Answer is C
Choice A rationale
Spironolactone is a potassium-sparing diuretic that acts on the collecting ducts and late distal tubules but not on the loop of Henle.
Choice B rationale
Hydrochlorothiazide is a thiazide diuretic that works on the distal convoluted tubule, not the loop of Henle.
Choice C rationale
Furosemide is a loop diuretic that acts on the ascending limb of the loop of Henle to inhibit sodium and chloride reabsorption, leading to increased urine output.
Choice D rationale
Mannitol is an osmotic diuretic that primarily acts on the proximal tubule and the descending limb of the loop of Henle.
