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.
