单项选择题
The nurse is caring for a client who underwent a subtotal gastrectomy 24 hours earlier. The client has a nasogastric (NG) tube. The nurse should
A. apply suction to the NG tube every hour.
B. clamp the NG tube if the client complains of nausea.
C. irrigate the NG tube gently with normal saline solution.
D. reposition the NG tube if pulled out.
答案
参考答案：C
解析：The nurse can gently irrigate the tube but must take care not to reposition it. Repositioning can cause bleeding. Suction should be applied continuously--not every hour. The NG tube shouldn’t be clamped postoperatively because secretions and gas will accumulate, stressing the suture line.
