護理師預防院內感染最有效的介入為何？
Which intervention by a nurse is most effective in preventing health care-associated infections (HAIs)?
- AUsing sterile gloves for every interaction每次接觸均使用無菌手套
- BProviding prophylactic antibiotics to every client為每位病人提供預防性抗生素
- CPerforming proper hand hygiene before and after client contact✓ 正解在接觸病人前後執行正確之手部衛生
- DLimiting visitors for all clients限制所有病人之探視
手部衛生（Hand hygiene）是預防院內感染（HAIs）最簡單、成本最低且最有效的措施。根據疾病管制與預防中心（CDC）指引，護理師在接觸病人前後、執行無菌操作前、接觸體液後均須正確執行洗手（使用肥皂或酒精乾洗手）。過度依賴手套會產生虛假安全感，甚至降低手部衛生遵從率。預防性抗生素會引發抗藥性，非預防感染之常規手段。
Hand hygiene is the simplest, lowest-cost, and most effective measure for preventing healthcare-associated infections (HAIs). According to CDC guidelines, nurses must perform proper hand hygiene (with soap and water or alcohol-based rub) before and after client contact, before aseptic procedures, and after contact with body fluids. Over-reliance on gloves creates a false sense of security and can reduce hand hygiene compliance. Routine prophylactic antibiotics promote resistance and are not a standard infection prevention strategy.
