護理師指導懷孕第二期的婦女營養需求，哪種飲食選擇顯示個案了解攝取鐵質的重要性？
A nurse is teaching a pregnant woman in her second trimester about nutritional needs. Which food choice indicates the client understands the need for increased iron intake?
- ASpinach salad with a side of citrus fruit✓ 正解菠菜沙拉搭配柑橘類水果
- BDairy products like yogurt with granola優格與穀片等乳製品
- CSteamed broccoli without any seasoning清蒸西蘭花（未加調味料）
- DA bowl of plain white rice一碗白飯
懷孕期間因胎兒生長與母體血容量增加，鐵質需求量大幅提升。菠菜富含「非血基質鐵（non-heme iron）」，其吸收率較低，但若與含有維生素 C（維生素 C）的柑橘類水果共同攝取，維生素 C 能將三價鐵還原為二價鐵，進而顯著提升腸道對鐵的吸收效率。這是在衛教孕婦營養需求時，兼顧生物利用率的臨床實務重點。
During pregnancy, iron requirements increase substantially due to fetal growth and the expansion of maternal blood volume. Spinach is rich in non-heme iron, which has relatively low absorption; however, when consumed together with citrus fruits rich in vitamin C, the vitamin C reduces ferric iron to ferrous iron, significantly enhancing intestinal absorption of iron. This is a key clinical practice point when teaching pregnant women about nutritional needs, addressing both adequate intake and bioavailability.
