病人的胸管意外滑脫，護理師應立即使用什麼物品以預防張力性氣胸？
A nurse is caring for a client with a chest tube that has been accidentally removed. Which supplies should the nurse immediately use to prevent a tension pneumothorax?
- AA plastic bag塑膠袋
- BSterile gauze pad無菌紗布墊
- CPetrolatum gauze dressing✓ 正解凡士林紗布敷料
- DAdhesive tape黏性膠帶
胸管滑脫後，胸膜腔與大氣相通，大氣壓力會瞬間灌入胸腔導致張力性氣胸（Tension pneumothorax），進而引發縱膈偏移及心肺衰竭。此時必須立即密封傷口。使用凡士林紗布（Petrolatum gauze）是標準處置，因為它具有氣密性，能有效阻隔空氣進入，並應以敷料覆蓋後僅固定三邊（或依機構政策），創造單向閥機制，讓胸腔氣體能排出但不吸入空氣。
After a chest tube is dislodged, the pleural cavity communicates with the atmosphere; atmospheric pressure rushes into the thoracic cavity, causing tension pneumothorax, which leads to mediastinal shift and cardiopulmonary failure. The wound must be sealed immediately. Petrolatum (Vaseline) gauze is the standard intervention because it is airtight and effectively blocks air entry; after applying the dressing, only three sides should be secured (or per institutional policy) to create a one-way valve mechanism that allows air to escape from the thoracic cavity without re-entering.
