A client in the intensive care unit has a presentation of pinpoint pupils, respiratory depression, and coma after overdosing on morphine sulfate (Astramorph). Which of the following is the appropriate complication based on the client's presentation?

Choice A rationale

Metoprolol is a beta-blocker that is commonly used to manage hypertension and control heart rate. It works by blocking beta-adrenergic receptors, which decreases heart rate and blood pressure.

Choice B rationale

Enoxaparin is an anticoagulant used to prevent and treat deep vein thrombosis and pulmonary embolism, not primarily to manage hypertension.

Choice C rationale

Heparin is an anticoagulant used to prevent and treat blood clots, and it is not indicated for the management of hypertension.

Choice D rationale

Simvastatin is a lipid-lowering medication used to manage high cholesterol levels and is not used to manage hypertension.

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.
