Ask the nurse to explain the type of angina he is experiencing.
The nurse explains the pain is due to the imbalance of myocardial supply.
Unstable.
Ischemic.
Stable angina.
Prinzmetal.
The Correct Answer is C
Choice A rationale
Unstable angina is characterized by sudden, severe chest pain that occurs at rest or with minimal exertion and is not relieved by nitroglycerin. It represents an imminent risk of myocardial infarction.
Choice B rationale
Ischemic heart disease can cause various types of angina, including stable, unstable, and Prinzmetal’s angina. The term “ischemic” refers to a lack of blood flow to the heart muscle, but this choice is too broad.
Choice C rationale
Stable angina occurs when there is an imbalance between myocardial oxygen supply and demand, typically during physical exertion or emotional stress. It is characterized by predictable chest pain that is relieved by rest or nitroglycerin.
Choice D rationale
Prinzmetal’s angina, also known as variant angina, is caused by a spasm in the coronary arteries, which leads to a temporary reduction in blood flow. It can occur at rest and is not necessarily related to the imbalance of myocardial supply and demand.
