A nurse is caring for a client with a new prescription for codeine.
Which of the following is an indication for this medication?

Choice A rationale

Beclomethasone (QVAR) is an inhaled corticosteroid used for long-term prophylaxis of asthma. It works by reducing inflammation in the airways, preventing asthma attacks and improving lung function.

Choice B rationale

Metoprolol is a beta-adrenergic blocker used for treating hypertension and certain heart conditions. It is not used for asthma management.

Choice C rationale

Phenytoin is an antiepileptic medication used to control seizures. It does not have a role in asthma management.

Choice D rationale

Furosemide is a loop diuretic used to treat conditions like edema and hypertension by promoting the excretion of excess fluid. It is not indicated for asthma management.

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.
