護理師照護一位中性球低下（neutropenia）的病人。下列哪項護理行動對於降低感染風險至關重要？
A nurse is caring for a client with neutropenia. Which action by the nurse is essential to minimize the risk of infection?
- AEnsure the client consumes only cooked vegetables確保個案僅食用煮熟蔬菜
- BPlace the client in a negative pressure isolation room將個案安置於負壓隔離室
- CImplement strict hand hygiene for all visitors and staff✓ 正解對所有訪客及醫護人員實施嚴格手部衛生
- DRestrict fresh flowers and potted plants in the room限制房間內放置鮮花與盆栽植物
中性球低下（neutropenia）的病人因免疫系統防禦力大幅下降，極易遭受伺機性感染。感染控制的核心是「阻斷傳播鏈」。洗手是預防醫療照護相關感染（HAI）最有效且具成本效益的方式。無論病人是否屬於中性球低下，訪客與醫護人員的嚴格洗手皆能有效減少病原體經由手部接觸傳播給病人的機率。其他選項如限制生食或環境控制（植物）雖為中性球低下病人的護理護理重點，但洗手是預防感染的首要防線。
A client with neutropenia is highly susceptible to opportunistic infections because immune defenses are markedly reduced. The core of infection control is 'breaking the chain of transmission.' Hand hygiene is the most effective and cost-effective method for preventing healthcare-associated infections (HAI). Whether or not a client is neutropenic, strict hand hygiene by visitors and healthcare workers effectively reduces the probability of pathogen transmission via the hands. Other options such as restricting raw foods or environmental control (plants) are also important nursing priorities for neutropenic clients, but hand hygiene remains the first line of defense against infection.
