单项选择题
The physician inserts a chest tube into a client to treat a pneumothorax. The tube is connected to water-seal drainage. The nurse can prevent chest tube air leaks by
A. keeping the chest drainage system below the level of the chest.
B. keeping the head of the bed slightly elevated.
C. checking and taping all connections.
D. checking patency of the chest tub
答案
参考答案：C
解析：Air leaks commonly occur if the system isn’t secure. Checking all connections and taping will prevent air leaks. The chest drainage system is kept lower to promote drainage--not to prevent air leaks. The head of the bed may be elevated to promote drainage. Chest tubes that aren’t patent may lead to tension pneumothorax but wouldn’t cause an air leak.
