護理師照護一位放置胸管的病人，發現水封瓶（water seal chamber）內有持續性氣泡。下列何者是優先的判讀？
A nurse is caring for a client with a chest tube drainage system. The nurse notes continuous bubbling in the water seal chamber. What is the priority interpretation?
- AThe lung has fully re-expanded肺部已完全復張
- BThe client has a large pneumothorax病人患有大量氣胸
- CThere is a leak in the system✓ 正解系統存在漏氣
- DThe suction is set too high抽吸設定過高
水封瓶應出現呼吸性波動（隨吸氣上升、吐氣下降），但不應出現持續性氣泡。若持續冒泡，代表胸腔內或胸管系統中有空氣持續進入，即所謂的 air leak。需檢查接頭處是否鬆脫或破裂。若管子拔除或系統破損，空氣會從外部進入，這對病人呼吸穩定造成嚴重威脅。
The water-seal chamber should show respiratory fluctuation (rising with inhalation and falling with exhalation) but should not show continuous bubbling. If continuous bubbling occurs, it means that air is continuously entering the pleural cavity or the chest drainage system, which is an air leak. The connections should be checked for looseness or breakage. If the tubing is dislodged or the system is damaged, air will enter from the outside, posing a serious threat to the patient's respiratory stability.
美台臨床皆視持續冒泡為重大系統異常，但美國護理師更強調自我操作系統檢查（如夾管測試尋找漏點）之專業權限。
