Which of the following would be an appropriate therapeutic adjustment for this patient?

Correct Answer: A

Rationale: The correct answer is A because milrinone is a positive inotrope that can be used as an alternative to digoxin for heart failure. Discontinuing digoxin is appropriate if the patient is experiencing toxicity symptoms. Starting milrinone provides the necessary positive inotropic support without the risk of digoxin toxicity. Option B is incorrect because physostigmine is used for anticholinergic toxicity, not digoxin toxicity. Decreasing the digoxin dose alone may not be sufficient to address toxicity symptoms. Option C is incorrect because atropine is used for bradycardia and not for digoxin toxicity. Decreasing the digoxin dose alone may not be sufficient to address toxicity symptoms. Option D is incorrect because metoprolol is a beta-blocker and can worsen symptoms of digoxin toxicity by further slowing the heart rate. Discontinuing digoxin is appropriate, but starting metoprolol is not recommended.
