護理師與孕婦討論營養需求，下列哪項飲食建議適用於健康孕期？
A nurse is discussing nutrition with a client who is pregnant. Which dietary recommendation is appropriate for a healthy pregnancy?
- ARestrict salt intake completely to prevent edema完全限制鹽分攝取以預防水腫
- BIncrease folic acid intake before and during early pregnancy✓ 正解在懷孕前及懷孕早期增加葉酸攝取
- CDouble caloric intake to support fetal growth將熱量攝取加倍以支持胎兒生長
- DAvoid all forms of physical exercise until the third trimester避免所有形式的體力活動直到第三孕期
孕期營養對於母嬰健康至關重要。葉酸（Folic acid）對於胎兒神經管發育至關重要，應在懷孕前及早期攝取充足。過度增加熱量（Double intake）會導致體重增加過多，引發妊娠糖尿病或高血壓；規律且適度的運動有利於孕期健康；鹽分攝取則應維持正常，不需完全禁鹽，因為鈉在電解質平衡中仍有功能。護理師應依據病人的體重與身體狀況，提供個性化的飲食建議。
Prenatal nutrition is essential for both mother and fetus. Folic acid is critical for fetal neural tube development and should be taken before and during early pregnancy. Doubling caloric intake leads to excess weight gain and risks of gestational diabetes or hypertension; regular moderate exercise is beneficial; sodium intake should remain normal—not eliminated—since sodium is needed for electrolyte balance. Individualized recommendations should be based on the client's weight and condition.
