A patient calls in to the emergency room and tells the nurse they are having chest pain. They are instructed to sit down and rest.

Their chest pain starts to go away with rest.

The nurse suspects which disorder?

Coronary artery disease.

Angina pectoris.

Congestive heart failure.

Myocardial infarction.

Answer and Explanation

The Correct Answer is B

Choice A rationale:
Coronary artery disease is a chronic condition that develops over time, not typically associated with chest pain that resolves with rest.
Choice B rationale:
Angina pectoris is characterized by chest pain that often improves with rest, as the heart’s demand for oxygen decreases.
Choice C rationale:
Congestive heart failure usually presents with symptoms like shortness of breath, fatigue, and swelling, not necessarily chest pain.
Choice D rationale:
Myocardial infarction, or a heart attack, typically causes severe chest pain that does not improve with rest.
