護理師照護一位因化療導致嗜中性球低下（neutropenia）的病人，下列哪項措施最能預防感染？
A nurse is managing a client receiving chemotherapy who is experiencing neutropenia. Which nursing intervention is MOST critical for preventing infection?
- AImplement strict hand hygiene for all individuals entering the room✓ 正解對所有進入房間的人實施嚴格的手部衛生
- BProvide a private room提供單人病房
- CMonitor temperature every 4 hours每 4 小時監測體溫
- DAdminister prophylactic antibiotics給予預防性抗生素
化療導致的嗜中性球低下（Neutropenia）會使病人免疫力極度低下，任何環境中的細菌皆可能導致致命性感染。預防感染的核心在於阻斷病原體傳播。嚴格的手部衛生（Hand hygiene）是防止病原體從醫護人員、訪客或環境傳播到病人的最基本、最重要措施。雖然單人房、抗生素和體溫監測都重要，但手部衛生是感染控制的第一道防線。
Chemotherapy-induced neutropenia leaves patients severely immunocompromised, so any organism—even endogenous flora—can cause life-threatening infection. Strict hand hygiene by every person entering the room is the single most effective and evidence-based measure to interrupt pathogen transmission. Prophylactic antibiotics, a private (sometimes protective) room, and frequent temperature monitoring are adjuncts, but hand hygiene is the foundational standard of care.
