護理師監督新進人員進行氣管抽痰時，哪項行為需要立即介入？
A nurse is supervising a newly licensed nurse performing tracheal suctioning. Which action by the new nurse requires immediate intervention?
- AApplying suction while inserting the catheter✓ 正解在插入導管時施加抽吸
- BUsing a sterile technique during the procedure在操作期間使用無菌技術
- CLimiting suction time to 10 seconds將抽吸時間限制在 10 秒內
- DHyperoxygenating the client before suctioning在抽吸前為病人補充高濃度氧氣
氣管抽痰（tracheal suctioning）屬於無菌操作，且需嚴格遵守呼吸道照護原則。抽吸過程中，導管插入時不可開啟負壓，以免損傷氣管黏膜並造成缺氧。正確做法應在插入到位後，採間歇性抽吸並邊旋轉邊退出。新進人員若在插入時即開啟負壓，會對病人造成直接傷害，護理師必須立即介入以保障病人安全（Safety）。
Tracheal suctioning is a sterile procedure that requires strict adherence to airway care principles. During suctioning, negative pressure must not be applied while the catheter is being inserted, in order to avoid damaging the tracheal mucosa and causing hypoxia. The correct technique is to apply intermittent suction with a rotating motion only while withdrawing the catheter after it has been advanced into position. If a new nurse applies suction during insertion, it causes direct harm to the client, and the supervising nurse must intervene immediately to safeguard patient safety.
