護理師教導病人高纖維飲食。哪項衛教內容對預防併發症至關重要？
A nurse is teaching a client about a high-fiber diet. Which instruction is essential to prevent complications?
- ALimit fluid intake to 500 mL daily將液體攝取量限制於每日 500 毫升
- BAvoid all protein when eating fiber攝取纖維時避免所有蛋白質
- CEat fiber only at dinner僅在晚餐時攝取纖維
- DIncrease fluid intake as fiber intake increases✓ 正解隨著纖維攝取量增加而增加液體攝取

高纖維飲食是促進腸道健康、預防便秘的重要方法，但若沒有搭配足夠的液體攝取，反而可能導致嚴重併發症。纖維在腸道中會吸收水分，增加糞便體積，進而刺激腸蠕動。然而，如果體內水分不足，纖維會從腸道中吸取過多水分，使糞便變得乾硬，不僅無法順利排出，更可能加劇便秘，甚至導致糞便嵌塞（fecal impaction）或腸阻塞（bowel obstruction）。因此，衛教病人高纖維飲食時，務必強調同步增加液體攝取，以確保纖維能發揮其正常功能，避免潛在的危險。
Increasing fluid intake is essential when consuming a high-fiber diet because fluids help soften stool and facilitate the movement of fiber through the digestive tract. Without adequate hydration, high fiber intake can lead to constipation, fecal impaction, or bowel obstruction.
✦ 台美臨床差異
美國市售纖維補充劑 (如 Metamucil) 非常普遍；台灣傾向從天然蔬果中攝取。
