The nurse anticipates that which is a goal of antianginal therapy?
1. Increase blood flow to the peripheral blood vessels.
2. Increase myocardial contractility.
3. Increase the oxygen consumption of the heart.
4. Reduce the frequency of angina episodes.
Correct Answer: 4
Rationale 1: Increasing blood flow to peripheral blood vessels will not help angina.
Rationale 2: Increasing myocardial contractility will actually make angina worse.
Rationale 3: Angina is caused by a mismatch in myocardial blood flow and myocardial oxygen demand. Increasing the heart's oxygen consumption can cause angina.
Rationale 4: A primary goal of pharmacotherapy for angina is to reduce the frequency and intensity of angina episodes. Additionally, successful pharmacotherapy should improve exercise tolerance and allow the client to actively participate in activities of daily living.
