一位 25 歲孕婦詢問懷孕期間運動的安全性。下列護理師的回應何者最為適切？
A 25-year-old client asks about the safety of exercise during pregnancy. Which nursing response is most appropriate?
- AYou must increase your heart rate to 160 beats per minute to benefit the fetus.您必須將心率提升至每分鐘 160 次才能對胎兒有益
- BIt is safe to continue moderate-intensity activities if you were active before pregnancy.✓ 正解如果您在懷孕前就有運動習慣，繼續進行中等強度的活動是安全的
- CYou should avoid all forms of physical activity until after birth.您應該避免所有形式的體力活動直到分娩後
- DYou should lie flat on your back for exercises to avoid balance issues.您應該仰臥進行運動以避免平衡問題
懷孕並非病理狀態，適度運動對母嬰均有益處。對於孕前已有運動習慣的女性，維持中等強度的運動是安全且被鼓勵的，能改善心肺功能並減緩孕期不適。護理師應評估病人的產科狀況，排除前置胎盤、子宮頸閉鎖不全等禁忌症，並教導避免過度勞累及長時間仰臥，以防壓迫下腔靜脈（Vena Cava Compression Syndrome）。
Pregnancy is not a pathologic state, and moderate exercise benefits both mother and fetus. For women who exercised regularly before pregnancy, maintaining moderate-intensity activity is safe and is encouraged, as it improves cardiopulmonary function and reduces pregnancy-related discomfort. The nurse should assess the client's obstetric status, rule out contraindications such as placenta previa and incompetent cervix, and instruct the client to avoid overexertion and prolonged supine positioning to prevent compression of the inferior vena cava (vena cava compression syndrome).
