A nurse is reviewing the laboratory results for a client receiving chemotherapy. Which finding should the nurse prioritize to prevent infection?
- APlatelets 95,000/mm³血小板 95,000/mm³
- BAbsolute Neutrophil Count (ANC) 450/mm³✓ 正解絕對中性球計數 (ANC) 450/mm³
- CWhite blood cell count 3,500/mm³白血球計數 3,500/mm³

化療病人常因骨髓抑制（Myelosuppression）導致免疫力下降。中性球（Neutrophils）是身體抵抗細菌感染的第一道防線，ANC（絕對中性球計數）是評估感染風險最準確的指標。當 ANC 低於 500/mm³ 時，病人處於嚴重中性球減少症，極易發生致命的伺機性感染，必須優先採取保護性隔離措施。
Chemotherapy often causes myelosuppression, leading to neutropenia, which severely compromises the body's ability to fight bacterial infections. The Absolute Neutrophil Count (ANC) is the most accurate indicator of infection risk, with values below 500/mm³ indicating severe neutropenia. This condition places the client at extreme risk for opportunistic infections, necessitating immediate protective isolation and prioritized nursing interventions.
