護理師照護一位接受放射性植入治療的病人，下列何者為優先安全防護？
A nurse is caring for a client with a radioactive implant. Which safety precaution is priority?
- ALimit the duration of time spent in the room✓ 正解限制在房間內的停留時間
- BEncourage the client to move about the room freely鼓勵病人在房間內自由走動
- CAllow visitors to stay for 60 minutes允許訪客停留六十分鐘
- DWear a lead apron at all times inside the room在房間內始終穿著鉛衣

放射性植入治療的輻射防護原則為「時間、距離、屏蔽」。限制與病人接觸的時間是減少暴露最有效的措施。訪客時間通常限制在 30 分鐘內；病人應限制活動以免植入物脫落；鉛圍裙對於特定高能量輻射效用有限，限制時間更為關鍵。
The principles of radiation protection for radioactive implants are time, distance, and shielding. Limiting the time spent in contact with the client is the most effective way to reduce exposure. Visitor time is typically limited to 30 minutes; the client should restrict movement to avoid dislodging the implant; lead aprons have limited effectiveness against certain high-energy radiation, so limiting time is more critical.
✦ 台美臨床差異
美國醫院針對放射性物質有極嚴格的劑量偵測與佩戴徽章要求，台灣相關規範亦趨於嚴格化。
