一位患有急性呼吸窘迫症候群（ARDS）的病人正在接受機械通氣，護理師聽到尖峰吸氣壓力警報響起。應優先採取何種行動？
A client is diagnosed with acute respiratory distress syndrome (ARDS) and is currently intubated on mechanical ventilation. The nurse notes the peak inspiratory pressure alarm is sounding. Which action should the nurse take first?
- AAuscultate the lungs for breath sounds✓ 正解聽診肺部呼吸音
- BSuction the endotracheal tube to clear secretions抽吸氣管內管以清除分泌物
- CSedate the client to reduce ventilator asynchrony鎮靜客戶以降低通氣不同步
- DIncrease the fraction of inspired oxygen (FiO2)增加吸入氧氣濃度 (FiO2)
呼吸器尖峰吸氣壓力警報觸發通常代表肺部阻力增加或順應性下降。首先必須評估病人呼吸音，確認有無支氣管痙攣、痰液阻塞或氣胸等急症。直接抽痰（B）可能無效若非分泌物問題，調整氧氣（D）不能解決壓力過高，鎮靜（C）應在排除機械與生理阻塞後考慮。
Activation of the peak inspiratory pressure alarm on a ventilator generally indicates increased pulmonary resistance or decreased compliance. The nurse must first assess the client's breath sounds to identify acute problems such as bronchospasm, mucus plugging, or pneumothorax. Suctioning (B) may be ineffective if secretions are not the cause; adjusting oxygen (D) will not resolve elevated airway pressure; and sedation (C) should be considered only after mechanical and physiological obstructions have been ruled out.
美國護理師常依呼吸治療協定執行初步評估；台灣臨床常需先呼叫呼吸治療師（RT）協助評估管路。
