单项选择题
A client is admitted with a suspected diagnosis of an acute myocardial infarction. When providing care for the client, the nurse should avoid which route when taking a temperature（）
A. Oral.
B. Rectal.
C. Axillary.
D. Tympanic.
答案
参考答案：B
解析：
When caring for the client with a cardiac disorder, the rectal route should be avoided. Introducing a thermometer into the rectum may stimulate the vagus nerve, causing vasodilation and bradycardia. The oral, axillary, and tympanic routes are appropriate for measuring the temperature of cardiac clients.
