The nurse is teaching a class on antianginal drugs to a group of patients who have experienced myocardial infarctions (MIs). The nurse determines that learning has occurred when a patient makes which statement?
1. "These medications decrease how much oxygen my heart needs."
2. "These medications thin my blood so my heart receives more oxygen."
3. "These medications increase the amount of oxygen my heart receives."
4. "These medications increase oxygen to my heart by increasing nitric oxide production."
Correct Answer: 1
Rationale: The primary means by which antianginal drugs terminate an acute angina episode, or decrease the frequency of angina episodes, is by reducing the myocardial demand for oxygen. Antianginal medications cannot increase the oxygen supply to the myocardium. Antianginal medications do not have an anticoagulant effect. Antianginal medications do not increase nitric acid production.
