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.

    Earthquakes happen without warning (前兆). They can happen any time of a day, at any point during the

year. When an earthquake is happening, you should know what you should do or not do.

    Do NOT go outside.You could get injured from falling glass or parts of buildings. If you are outside, stay

away from buildings and power lines (输电线).

    Stay under a desk, table, or other strong furniture. Hold on to it. Or stay in a corner of the building. Cover

your face and head with your arms and cover your mouth with a towel or clothing. Stay inside until shaking

stops and it is safe to go outside.
