A client is newly prescribed with metformin (Glucophage) for type 2 diabetes.Which of the following statements indicate that the client understands the teaching of metformin?

Choice A rationale

Aspirin is a first-generation NSAID that reduces inflammation and pain. It works by inhibiting the enzyme cyclooxygenase, which results in decreased production of prostaglandins.

Choice B rationale

Dimenhydrinate is an antihistamine used to prevent and treat nausea, vomiting, and dizziness caused by motion sickness. It is not considered an NSAID.

Choice C rationale

Cetirizine is an antihistamine used to relieve allergy symptoms. It is not considered an NSAID.

Choice D rationale

Celecoxib is a second-generation NSAID that selectively inhibits cyclooxygenase-2 (COX-2). It is not a first-generation NSAID.

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.
