单项选择题
Before a transesophageal echocardiogram, a client is given an oral topical anesthetic spray. Upon return from the procedure, the nurse observes that the client has no active gag reflex. In response, the nurse should（）
A. insert an oral airway.
B. withhold food and fluids.
C. position the client on his side.
D. introduce a nasogastric (NG) tube.
答案
参考答案：B
解析：
Following a transesophageal echocardiogram in which the client’s throat has been anesthetized, food and fluid should be withheld until the gag reflex returns. There is no indication for oral airway placement. The client should be in the upright position, and inserting an NG tube is unnecessary.
