Which class of medications will the nurse expect to be prescribed for a patient with angina pectoris and known coronary artery disease (CAD)? Calcium channel blockers Nitrates Beta-blockers ACE inhibitors

For a patient with angina pectoris and known coronary artery disease (CAD), the nurse can expect any of the following classes of medications to be prescribed, as they are commonly used in managing these conditions:

1. **Nitrates**: These are often used to relieve angina symptoms by dilating blood vessels, which increases blood flow to the heart muscle and reduces its workload.

2. **Beta-blockers**: These medications help reduce the heart rate and the force of contraction, thereby decreasing the heart's oxygen demand and helping to prevent angina attacks.

3. **Calcium channel blockers**: These can be used to relax and widen blood vessels, improving blood flow to the heart and reducing or preventing angina.

While ACE inhibitors are primarily used for hypertension and heart failure, they may also be prescribed for patients with CAD to improve cardiovascular outcomes, but they are not typically first-line treatments specifically for angina symptoms.

Therefore, nitrates, beta-blockers, and calcium channel blockers are the most directly relevant classes of medications for treating angina pectoris in the context of CAD.
