When given together, the digoxin dosage may need adjustment, and the nurse should closely monitor the client's digoxin levels to prevent toxicity symptoms such as nausea, vomiting, visual disturbances, and arrhythmias.

Correct Answer: C

Rationale: The client's symptoms indicate circulatory overload, which can occur during blood transfusions. Furosemide, a loop diuretic, is commonly prescribed in such cases to help relieve manifestations of circulatory overload by promoting diuresis and reducing fluid volume. Epinephrine is used for severe allergic reactions, lorazepam for anxiety or seizures, and diphenhydramine for mild allergic reactions or as a sedative.

Correct Answer: B

Rationale: The correct answer is to monitor the client's potassium levels. Hypokalemia can increase the risk of Digoxin toxicity. Potassium levels should be closely monitored to prevent adverse effects.
