照護一位急性呼吸窘迫症候群（ARDS）病人，哪些護理措施是適當的？（選所有適合的）
A nurse is caring for a client with acute respiratory distress syndrome (ARDS). Which actions are appropriate? (Select all that apply.)
- AMaintain prone positioning✓ 正解維持俯臥姿勢
- BMonitor oxygen saturation continuously✓ 正解持續監測血氧飽和度
- CAdminister high-dose steroids給予高劑量類固醇
- DRestrict fluids to avoid lung edema限制液體攝取以避免肺水腫
- EPrepare for mechanical ventilation✓ 正解準備機械通氣
急性呼吸窘迫症候群（ARDS）是嚴重的急性肺部發炎，導致廣泛性肺泡塌陷、嚴重缺氧。治療重點包括：俯臥位（Prone positioning）以改善肺部背側通氣灌流比；機械通氣（Mechanical ventilation）以維持氧合與通氣；持續監測氧合狀況（SpO2, ABG）。類固醇使用具爭議性。液體管理需嚴謹，過多會加重肺水腫，過少則引發低血壓。
Acute respiratory distress syndrome (ARDS) is a severe acute lung inflammation that leads to widespread alveolar collapse and severe hypoxemia. Key elements of management include prone positioning to improve the ventilation-perfusion ratio in the dorsal lung regions, mechanical ventilation to support oxygenation and ventilation, and continuous monitoring of oxygenation (SpO2 and ABGs). The use of steroids remains controversial. Fluid management must be balanced -- excess fluid worsens pulmonary edema while too little causes hypotension.
