護理師正在為一位懷孕 10 週的初產婦提供衛教。為了促進胎兒健康，護理師應強調下列哪項生活方式的調整？
A nurse is providing teaching to a primigravida client at 10 weeks gestation. Which lifestyle modification should the nurse emphasize to promote fetal health?
- AEnsure a daily intake of at least 400 to 800 mcg of folic acid✓ 正解確保每日攝取至少 400 至 800 mcg 的葉酸
- BLimit caffeine intake to no more than 500 mg per day將咖啡因攝取量限制在每日不超過 500 mg
- CIncrease caloric intake by 500 kcal/day starting immediately立即開始每日增加 500 kcal 的熱量攝取
- DAvoid all forms of physical exercise to prevent preterm labor避免任何形式的體育運動以防早產
在懷孕初期，健康促進的核心在於預防神經管缺陷（NTD）與支持早期胚胎發育。葉酸（Folic acid）的補充是此階段最重要的介入措施。雖然在懷孕前補充效果最好，但懷孕早期持續補充 400-800 mcg 能有效降低脊柱裂等風險。關於其他選項：第一孕期並不需要顯著增加熱量（通常到第二、三孕期才需增加約 340-450 kcal），因此 C 錯誤；適度的運動（如散步）對多數孕婦是有益的，不應完全禁止，故 D 錯誤；咖啡因建議限制在 200 mg 以下而非 500 mg，故 B 錯誤。臨床護理重點在於精確的營養指導與劑量掌握，確保產婦理解微量營養素對胎兒器官形成的關鍵作用。
In early pregnancy, the core of health promotion is preventing neural tube defects (NTDs) and supporting early embryonic development. Folic acid supplementation is the most important intervention at this stage. Although supplementation is most effective before conception, continued intake of 400-800 mcg in early pregnancy effectively reduces the risk of conditions such as spina bifida. Regarding the other options: significant caloric increases are not needed in the first trimester (typically an additional 340-450 kcal is recommended only in the second and third trimesters), so C is incorrect; moderate exercise (such as walking) is beneficial for most pregnant women and should not be completely forbidden, so D is incorrect; caffeine should be limited to under 200 mg rather than 500 mg, so B is incorrect. The clinical nursing focus is on precise nutritional guidance and dosing, ensuring the mother understands the critical role of micronutrients in fetal organogenesis.
美國護理實務非常強調葉酸補充的具體劑量教育，且市售孕婦維他命規格統一。台灣護理師在產檢衛教時，亦會強調葉酸與鐵質攝取，但台灣產婦常受傳統習俗影響而過度限制活動（如動到胎氣），護理師需特別針對運動安全性進行實證衛教。
