A nurse is caring for a client with a new prescription for digoxin for one week.
The client reported having blurred vision, vomiting, and weight loss of 4 pounds in one week.
Which of the following medications should the nurse anticipate to give to the client based on the presenting symptoms?

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.

Choice A rationale

Codeine is an opioid used for the treatment of chronic nonproductive cough by decreasing the frequency and intensity. It acts on the brain to reduce the urge to cough, providing symptomatic relief for chronic, dry cough.

Choice B rationale

Codeine is not specifically used to treat allergic rhinitis. Medications such as antihistamines and corticosteroids are more commonly used for this condition.

Choice C rationale

Codeine is not used for non-allergic rhinitis. It is primarily an antitussive agent used to manage chronic cough, not for nasal conditions.

Choice D rationale

This choice is incorrect as codeine has specific indications, including the treatment of chronic nonproductive cough, pain relief, and sometimes as an antidiarrheal.
