護理師正在衛教一位預計明天早上進行大腸鏡檢查的病人。下列哪項指導內容應包含在內？
A nurse is teaching a client about a colonoscopy scheduled for the next morning. Which instruction should the nurse include?
- ADrink only clear liquids for dinner✓ 正解晚餐僅攝取清流質
- BConsume a heavy meal tonight to maintain energy今晚攝取豐盛餐點以維持體力
- CDrink 2 liters of orange juice with pulp before the exam檢查前飲用 2 公升帶果肉柳橙汁
- DMaintain a full bladder for better visualization保持膀胱充盈以利視野清晰
— Explanation · 中文詳解 —
大腸鏡檢查前需進行嚴格的腸道準備，以確保視野清晰。通常檢查前一天需採清流質飲食（Clear liquid diet），避免固體食物或含殘渣的液體（如含果肉的果汁）。檢查當天通常需服用清腸劑，並非保持膀胱漲滿。
Proper bowel preparation is essential for colonoscopy visualization, requiring a clear liquid diet the evening before the procedure to reduce residue. Patients should avoid fluids with pulp or red/purple dyes, which can mimic blood or obscure the view. A full bladder is unnecessary for this procedure and does not aid in bowel cleansing.
✦ 台美臨床差異
美國常用的清腸藥物如 GoLYTELY 份量較大，護理師需強調水分補充；台灣常使用份量較小的磷酸鈉鹽，需注意電解質平衡。
