護理師審查一位進行體內放射線治療（近接治療）病人的安全協定，哪些敘述顯示病人理解預防措施？（選所有適合的）
A nurse is reviewing safety protocols for a client receiving internal radiation therapy (brachytherapy). Which statements indicate an understanding of the precautions? (Select all that apply.)
- ALimit visitor time to 30 minutes per day✓ 正解將訪客時間限制在每天30分鐘
- BStay at least 6 feet away from the patient與病人保持至少6英尺的距離
- CWear a lead apron when providing direct care✓ 正解提供直接照護時穿著鉛衣
- DPregnant staff members should not care for this client✓ 正解懷孕員工不應照護此病人
- EThe client must remain on strict bed rest病人必須嚴格卧床休息

近接治療需嚴格落實輻射防護：時間、距離、屏蔽。限制訪客時間、護理人員穿戴鉛裙、禁止孕婦接觸（防胎兒畸形）。保持距離很重要但 6 呎過於嚴苛，通常為 6 呎距離外即可降低影響，但不代表「只能」在那個距離外。病患不必強制絕對臥床，但需限制活動範圍。
Understanding of brachytherapy precautions includes limiting visitor time to reduce cumulative radiation exposure, wearing lead aprons for shielding during direct care, and ensuring pregnant staff do not care for the client to protect the fetus. While distance reduces radiation intensity, strict bed rest is not required, though activity may be limited depending on the specific protocol.
✦ 台美臨床差異
美國核醫科與放療科有極嚴格的輻射安全官（RSO）監管，台灣醫院則多依賴放射線防護委員會規範。
