A nurse is caring for a client who is newly diagnosed with pancreatic cancer.
Which of the following is a treatment for cancer?

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.

Choice A rationale

Digoxin is a cardiac glycoside used for heart failure and arrhythmias, not a diuretic.

Choice B rationale

Spironolactone is a potassium-sparing diuretic, preventing hypokalemia.

Choice C rationale

Furosemide is a loop diuretic that can cause hypokalemia by increasing potassium excretion.

Choice D rationale

Captopril is an ACE inhibitor used for hypertension and heart failure, not a diuretic.
