How does the pain of a myocardial infarction (MI) differ from stable angina?
Correct Answer: C
Rationale: The correct answer is C because the pain of a myocardial infarction (MI) typically lasts longer than 15 minutes, unlike stable angina which lasts for a shorter duration. MI pain is usually described as intense, crushing, and prolonged, whereas stable angina pain is often triggered by exertion and relieved by rest or medication like nitroglycerin. Choices A, B, and D are incorrect because shortness of breath, feelings of fear or anxiety, and lack of relief from nitroglycerin are not definitive differentiating factors between MI and stable angina.
