一位術後胸管引流病人，下列何種情況需立即通知醫師？
A nurse is caring for a postoperative client who has a chest tube. Which finding should the nurse report to the provider immediately?
- APresence of 100 mL of serosanguineous drainage出現100 mL的漿液血性引流液
- BSmall subcutaneous emphysema around the insertion site插管周圍有少量皮下氣腫
- CContinuous bubbling in the water seal chamber✓ 正解水封瓶內持續冒泡
- DFluctuation in the water seal chamber with respiration水封瓶內隨呼吸出現波動
水封瓶持續性氣泡暗示氣胸未解決或系統漏氣。正常情況應隨呼吸波動（潮氣現象），若出現持續性氣泡，需檢查系統連接處是否脫落或管路破損。B 為正常表現，A 屬引流正常範圍，B 若範圍無擴大屬常見術後狀況，無需立即干預。
Continuous bubbling in the water seal chamber suggests an unresolved pneumothorax or a system air leak. Normally, fluctuation should occur with respiration (tidaling); if continuous bubbling is observed, the system connections must be checked for disconnection or tubing damage. Option D is a normal finding, option A falls within the normal range of drainage, and option B, if not enlarging, is a common postoperative finding and does not require immediate intervention.
美國護理師常需自行判斷氣泡來源（夾管測試），台灣醫療環境多由醫師操作或決定是否夾管。
