一位診斷為急性呼吸窘迫症候群（ARDS）且已插管的病人，呼吸器低壓警報響起。護理師應優先執行哪項措施？
A client is diagnosed with acute respiratory distress syndrome (ARDS) and is currently intubated. The low-pressure alarm on the ventilator sounds. Which action should the nurse perform first?
- ANotify the respiratory therapist immediately立即通知呼吸治療師
- BPerform endotracheal suctioning進行氣管內抽痰
- CIncrease the tidal volume on the ventilator settings增加呼吸器設定中的潮氣容積
- DAssess the client and the ventilator tubing for disconnections✓ 正解評估病人及呼吸器管路是否有脫落
呼吸器警報響起時，護理師的首要行動永遠是『評估病人』。低壓警報（Low-pressure alarm）最常見原因是管路脫落、氣囊洩漏或病人脫管，這會導致通氣失效（Ventilatory failure）。護理師應確保病人呼吸道安全，並檢查管路完整性。在確認病人狀況與管路連接前，不應隨意調整參數或請他人介入。
A low-pressure alarm on a ventilator typically indicates a disconnection in the tubing, a leak in the endotracheal tube cuff, or accidental extubation, all of which compromise airway integrity. The nurse must first assess the client and the ventilator circuit to identify and correct the source of the problem, ensuring the client remains oxygenated and ventilated. Interventions such as suctioning or adjusting settings are inappropriate until the cause of the low pressure is determined.
在美國臨床實務中，呼吸治療師（RT）與護理師分工明確，但『護理師優先評估病人及管路安全』的原則是 NCLEX 考試中絕對的優先級（Priority）。
