问题单项选择题

When assessing a client with chest pain, the nurse obtains a thorough history. Which statement by the client is most suggestive of angina pectoris（）

A. "The pain lasted for about 45 minutes. "

B. "The pain resolved after I ate a sandwich. "

C. "The pain worsened when I took a deep breath. "

D. "The pain occurred while I was mowing the lawn. "

答案

参考答案：D

解析：

Angina pectoris is chest pain caused by a decreased oxygen supply to the myocardium. Lawn mowing increases the cardiac workload, which increases the heart’s need for oxygen and can precipitate angina. Anginal pain typically is self-limiting and lasts 5 to 15 minutes. Food consumption doesn’t reduce this pain, but may ease pain caused by a GI ulcer. Deep breathing has no effect on anginal pain.
