護理師評估一位裝有胸管水封瓶系統的病人，哪種現象暗示系統有空氣洩漏？
A nurse is assessing a client who has a chest tube connected to a water-seal drainage system. Which finding indicates a potential air leak in the system?
- AAbsence of bubbling in the suction control chamber抽氣控制室內無氣泡
- BFluctuation of the fluid level in the water-seal chamber水封室內液面波動
- CDullness on percussion of the affected side患側叩診呈濁音
- DContinuous bubbling in the water-seal chamber✓ 正解水封室內持續氣泡
水封瓶應只有在病人咳嗽或呼氣時出現間歇性氣泡，若出現連續性氣泡表示系統氣密性不佳。連續氣泡提示空氣持續從系統外部進入或來自肺部漏氣，需檢查接口是否鬆脫。B 為正常呼吸波動；C 反映負壓狀態；D 是積液表現，與漏氣無直接關聯。
The water-seal chamber should bubble only intermittently when the client coughs or exhales. Continuous bubbling indicates that the system is not airtight. Continuous bubbling suggests that air is continuously entering the system from outside or leaking from the lung, and the connections should be checked for looseness. B represents normal respiratory fluctuation; C reflects negative-pressure status; C represents fluid accumulation and is not directly related to an air leak.
兩地對胸管護理標準一致，但在床邊排查漏氣來源的操作上，美國護理師常被訓練進行系統性夾管測試。
