護理師準備給予口服鐵劑。下列哪項衛教對安全性與有效性最重要？
A nurse is preparing to administer an oral iron supplement. Which teaching point is most important for safety and effectiveness?
- ATake with milk to avoid stomach upset與牛奶同服以避免胃部不適
- BTake on an empty stomach空腹服用
- CExpect stools to be dark green or black預期糞便會變成深綠色或黑色
- DTake with vitamin C to enhance absorption✓ 正解與維生素 C 同服以增強吸收
— Explanation · 中文詳解 —
口服鐵劑的吸收度受環境影響巨大。維生素 C（酸性環境）可顯著增強吸收率。乳製品（鈣）會阻礙吸收。雖建議空腹服用，但若有胃部不適，維生素 C 仍是提升效果的關鍵。大便變黑是正常現象（非安全性問題），不是衛教的首要。
Vitamin C creates an acidic environment that significantly enhances the absorption of oral iron supplements. While taking iron on an empty stomach improves absorption, it often causes gastrointestinal irritation, making vitamin C a key strategy for effectiveness even if food is required. Milk and dairy products should be avoided because calcium inhibits iron absorption.
