護理師正在照顧一位新接受氣切的病人。下列哪項措施對預防呼吸道阻塞至關重要？
A nurse is caring for a client with a new tracheostomy. Which action is essential to prevent airway obstruction?
- ASuction secretions as needed✓ 正解按需抽吸分泌物
- BKeep the head of the bed elevated 30 degrees將床頭抬高 30 度
- CPerform tracheostomy site care daily每日進行氣切部位護理
- DAdminister humidified oxygen給予濕化氧氣
氣切（Tracheostomy）術後病人最立即且致命的風險為人工氣道阻塞。由於氣切管內容易積聚分泌物，且病人初期咳嗽反射可能減弱，保持呼吸道通暢（Airway）是護理的首要任務。依需要抽痰（Suctioning）能直接移除分泌物，避免阻塞導致缺氧，符合 ABC（Airway, Breathing, Circulation）護理優先原則。
The most immediate and life-threatening risk after tracheostomy is obstruction of the artificial airway. Because secretions readily accumulate in the tracheostomy tube and the cough reflex may be diminished initially, maintaining airway patency is the foremost nursing priority. Suctioning as needed directly removes secretions and prevents hypoxia from obstruction, which is consistent with the ABC (Airway, Breathing, Circulation) priority framework of nursing care.
在美國臨床實務中，氣切抽痰執行時機極為嚴格遵循「依需要（PRN）」而非「固定時間（Routine）」，以減少對氣管黏膜的機械性傷害。
