A nurse is caring for a client who is prescribed ciprofloxacin for bacteremia.What is the mechanism of action for this medication?

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

Changing the route of administration does not mitigate the risks associated with Category D medications during pregnancy.

Choice B rationale

Administering the medication without further consultation can pose significant risks to the fetus.

Choice C rationale

Holding the medication and consulting with the physician ensures safety by verifying the necessity and potential risks associated with the medication.

Choice D rationale

Continuing the current medication administration without consulting the physician can put both the mother and fetus at risk.
