護理師諮詢病人預防流感，下列哪項護理行動最有效？
A nurse is counseling a client about the prevention of influenza. Which is the most effective nursing action?
- ASuggesting the use of vitamin C supplements建議使用維生素C補充劑
- BPromoting annual vaccination✓ 正解促進每年接種疫苗
- CEncouraging frequent handwashing鼓勵頻繁洗手
- DAvoiding all public gatherings避免參加所有公眾集會
預防流感的策略應聚焦於主動免疫與特異性防護。年度流感疫苗（Influenza Vaccine）能刺激免疫系統產生針對當年流行病毒株的抗體，是公衛領域公認最有效降低感染率與重症風險的方法。其他選項如洗手雖能阻斷傳播，但屬廣泛性感染控制措施；維生素 C 無法預防流感；避免社交則不具臨床實務可行性。護理師應優先推廣具備高實證支持的預防措施。
Influenza prevention strategies should focus on active immunization and pathogen-specific protection. The annual influenza vaccine stimulates the immune system to produce antibodies against the circulating viral strains for that year and is recognized in public health as the most effective method for reducing infection rates and severe disease. Other options such as handwashing can interrupt transmission but are general infection control measures, vitamin C does not prevent influenza, and avoiding social contact is not clinically feasible. The nurse should prioritize evidence-based preventive measures.
美國在流感疫苗推廣上極為積極，通常由藥師（Pharmacist）與護理師共同在社區藥局或診所提供服務，且強調「年度（Annual）」接種的重要性，這在台灣同樣是公衛推廣的核心。
