下列哪些跡象顯示接受近接放射治療（brachytherapy）的病人需要進一步監測？（選所有適合的）
Which of the following indicate a need for further monitoring in a client with a history of internal radiation therapy (brachytherapy)? (Select all that apply.)
- AThe radiation source was found in the bed linens✓ 正解發現輻射源位於床單上
- BThe client complains of fatigue病人抱怨疲倦
- CThe lead-lined container is not available in the room✓ 正解房間內沒有鉛襯容器
- DThe client is experiencing mild nausea病人經歷輕微噁心
- EThe client is ambulating to the bathroom alone✓ 正解病人獨自走到浴室
— Explanation · 中文詳解 —
近接治療植入物若滑落至床單（A），會造成環境輻射暴露，需立即用長鑷夾入鉛容器；房間內未配置鉛容器（C）違反輻射安全準則；植入物在位時，病人應限制活動以防移位（E）。疲勞與輕微噁心是常見副作用，雖需觀察但非輻射防護的直接危機。
Safety concerns include a dislodged radiation source, absence of a lead-lined container, and unrestricted ambulation. These situations pose significant radiation exposure risks and require immediate intervention to secure the source and limit patient movement.
✦ 台美臨床差異
美國對輻射安全有 NRC 嚴格監管；台灣由輻射防護官管理，護理師需遵守嚴格的佩戴劑量計規範。
