A nurse is caring for a client that will receive a diuretic.
Which of the following diuretics act on the distal tubule?
Furosemide.
Spironolactone.
Mannitol.
Hydrochlorothiazide.
The Correct Answer is D
Choice A rationale
Furosemide is a loop diuretic that acts on the ascending limb of the loop of Henle, not the distal tubule.
Choice B rationale
Spironolactone is a potassium-sparing diuretic that works on the collecting ducts and late distal tubules, not the distal tubule.
Choice C rationale
Mannitol is an osmotic diuretic that acts on the proximal tubule and the descending limb of the loop of Henle, not the distal tubule.
Choice D rationale
Hydrochlorothiazide is a thiazide diuretic that works on the distal convoluted tubule, making it the correct answer.

Correct Answer is {"dropdown-group-1":"C"}
Explanation
Choice A rationale: Furosemide is a loop diuretic used to reduce fluid overload in CHF patients. However, it can exacerbate electrolyte imbalances, particularly hypokalemia. Since the client is already experiencing muscle spasms and has low calcium levels, additional diuretic therapy could worsen these symptoms.
Choice B rationale: Metoprolol is a beta-blocker used to manage hypertension and heart rate in CHF patients. While beneficial for blood pressure control, it does not address the immediate issue of muscle spasms and constipation the client is experiencing.
Choice C rationale: Potassium chloride is indicated to address potential hypokalemia, which may be causing the client's muscle spasms. CHF patients on diuretics often experience low potassium levels, so supplementation is crucial to prevent complications and alleviate symptoms.
Choice D rationale: Acetaminophen is an analgesic and antipyretic, useful for pain and fever management. However, it does not address the client's reported muscle spasms, which are likely related to electrolyte imbalances.
Correct Answer is C
