一名病患診斷為急性呼吸窘迫症候群 (ARDS)。對於此病患，護理師的優先護理措施為何？
A client is diagnosed with acute respiratory distress syndrome (ARDS). What is the priority nursing intervention for this client?
- AEncourage deep breathing and coughing exercises鼓勵深呼吸和咳嗽練習
- BAdminister high-flow oxygen via non-rebreather mask通過非再呼吸面罩給予高流量氧氣
- CMaintain a prone position to improve oxygenation✓ 正解保持俯臥位以改善氧合
- DMonitor hourly intake and output監測每小時的進出量
急性呼吸窘迫症候群（ARDS）的核心病理是肺泡塌陷、肺部浸潤與嚴重的低血氧。俯臥位（Prone position）治療是 ARDS 臨床實證中極重要的護理措施。透過改變姿勢，重力會重新分配肺部的通氣灌流比（V/Q mismatch），使背側塌陷的肺泡重新擴張，進而改善氧合（Oxygenation）。此介入能減少呼吸機相關肺損傷，是改善 ARDS 病人預後的關鍵。
The core pathology of acute respiratory distress syndrome (ARDS) is alveolar collapse, pulmonary infiltration, and severe hypoxemia. Prone positioning is an evidence-based nursing intervention of major importance in ARDS. By changing the client's position, gravity redistributes the ventilation/perfusion (V/Q) ratio within the lungs, allowing collapsed dorsal alveoli to re-expand and thereby improving oxygenation. This intervention can also reduce ventilator-associated lung injury and is critical for improving outcomes in clients with ARDS.
