一位病人正在接受內放射治療（近接治療），下列哪項護理措施最恰當？
A client is receiving internal radiation therapy (brachytherapy). Which nursing action is most appropriate?
- AAllow visitors for up to 2 hours per day允許訪客每天最多探視 2 小時
- BLimit time spent in the room to 30 minutes per shift✓ 正解限制在房間內的時間為每班 30 分鐘
- CStay at the door to communicate with the client站在門外與病人溝通
- DEncourage the client to get out of bed for exercise鼓勵病人下床活動
近接治療（brachytherapy）安全照護依輻射防護三原則：時間（time）、距離（distance）、屏蔽（shielding）。護理師應限制每次照護時間（A. 通常每班 30 分鐘為標準），同時保持最大可行距離並使用鉛屏蔽。「站在門口溝通」（C）過度避免進入會忽略病人基本照護需求（如生命徵象、評估、給藥），不是恰當做法——應在進房時運用時間與距離原則進行必要照護。其他選項：A. 訪客時間應更嚴格（每天 30 分鐘以下，需保持距離）；D. 病人需臥床休息以防放射源移位。
Safe care during brachytherapy follows the three principles of radiation protection: time, distance, and shielding. The nurse should limit time spent in the room each shift (A, typically 30 minutes per shift), maintain maximum feasible distance, and use lead shielding. 'Communicating from the doorway only' (C) excessively avoids entering and neglects essential patient care needs (such as vital signs, assessment, medication administration), which is not appropriate – the nurse should enter the room and apply the time/distance/shielding principles to provide necessary care. Other options: B. Visitor time should be more strictly limited (less than 30 minutes per day at distance); D. The patient must remain on bed rest to prevent dislodgement of the radioactive source.
美台皆強調 Radiation Safety Officers (RSO) 規範，病房門口皆會有醒目的輻射警示標誌。
