病人正準備接受上消化道內視鏡（EGD）檢查。檢查結束後，哪項護理措施是首要重點？
A client is being prepared for an upper gastrointestinal endoscopy (EGD). Which nursing intervention is a priority following the procedure?
- AEncourage deep breathing exercises鼓勵深呼吸運動
- BOffer clear liquids immediately立即提供清流質飲食
- CKeep the client in a side-lying position讓客戶保持側臥姿勢
- DMonitor for the return of the gag reflex✓ 正解監測咽反射是否恢復
EGD 過程中常對咽喉部使用局部麻醉藥以抑制嘔吐反射。術後必須先確認咽喉反射（Gag reflex）恢復後才能進食或飲水，否則有極高的吸入性肺炎風險。側臥有助於排除分泌物，但確認反射才是進食安全的關鍵。進食透明液體必須在反射恢復後。
Topical anesthetics are commonly applied to the throat during EGD to suppress the gag reflex. After the procedure, the gag reflex must be confirmed to have returned before the client may eat or drink; otherwise there is a very high risk of aspiration pneumonia. Side-lying position helps drain secretions, but confirming the return of the reflex is the key to safe oral intake. Clear liquids may only be provided after the reflex has returned.
美國護理師常需在 PACU 自行測試病人反射；台灣檢查室護理師通常會衛教病人 1-2 小時後試喝水，不一定會逐一測試反射，但原則一致。
