護理師照護一位接受化學治療的病人，發現絕對嗜中性白血球數（ANC）為 400/mm³，哪項護理措施為優先？
A nurse is caring for a client receiving chemotherapy. The nurse notes the client's absolute neutrophil count (ANC) is 400/mm³. Which action is the priority?
- APlace the client in a private room with neutropenic precautions✓ 正解將病人安置於執行中性粒細胞缺乏防護措施的單人病房
- BAdminister prophylactic antibiotics給予預防性抗生素
- CRestrict all visitors from entering the room禁止所有訪客進入病房
- DEncourage the client to eat fresh fruits and vegetables鼓勵病人食用新鮮水果和蔬菜
ANC < 500/mm³ 代表病人處於嚴重嗜中性白血球低下狀態（Severe Neutropenia），極易發生致命性感染。優先措施是執行保護性隔離（Neutropenic precautions），包括入住獨立房間、限制感染源接觸。抗生素需醫師開立，水果生食應嚴格限制，而非鼓勵。
An absolute neutrophil count (ANC) of 400/mm³ indicates severe neutropenia, placing the client at high risk for life-threatening infections. The priority action is to implement neutropenic precautions, such as placing the client in a private room, to minimize exposure to pathogens, whereas fresh foods should be restricted and antibiotics require a provider order.
美國 Oncology 病房對 Neutropenic precautions 有非常嚴格的 Standard Protocol；台灣臨床則視各院感染管制規定執行，差異度較大。
