Answer :
Final answer:
The nurse should immediately question the prescription of Potassium 10 meq PO once daily because it could incite hyperkalemia (high potassium levels in the blood) as the patient is already on Spironolactone which potentially already elevates potassium levels.
Explanation:
Given the medical condition expressed, the nurse should immediately question the prescription for Potassium 10 meq PO once daily. This is because the patient is already on Spironolactone, a medication known to increase potassium levels in the body which may lead to hyperkalemia(high potassium levels in the blood), a dangerous condition particularly for a patient with cardiovascular disease such as recurrent angina. Beta blockers like Metoprolol and calcium channel blockers like Diltiazem are commonly used to manage both angina and hypertension and should not be questioned in this context. Overprescription may lead to bradycardia but given the doses provided this does not seem probable.
