護理師在社區診所工作。下列哪項活動是預防流感的「一級預防」措施？
A nurse is working in a community clinic. Which activity is a primary prevention measure for influenza?
- AProviding hospitalization for complicated flu提供重症流感之住院治療
- BMonitoring community flu outbreak statistics監測社區流感疫情統計數據

預防醫學分為三階段：一級預防（Primary Prevention）旨在疾病發生前消除致病因子或增強抵抗力；二級預防（Secondary Prevention）側重早期篩檢與治療；三級預防（Tertiary Prevention）則針對已發病者進行復健與併發症控制。流感疫苗屬於一級預防，透過主動免疫預防感染發生，是社區護理的優先任務。
Preventive medicine is divided into three stages: primary prevention aims to eliminate causative factors or strengthen resistance before a disease occurs; secondary prevention focuses on early screening and treatment; tertiary prevention focuses on rehabilitation and management of complications in those already affected. Influenza vaccination belongs to primary prevention, using active immunization to prevent infection from occurring, and is a priority task in community nursing.
