護理師照護一位懷疑有感染性疾病的病人，為維持感染控制，應優先採取哪項措施？
A nurse is caring for a client with a suspected infectious disease. Which action should the nurse take first to maintain infection control?
- AInform the client's family about the diagnosis告知病人家屬診斷結果
- BReview the client's laboratory results檢視病人之實驗室檢驗結果
- CImplement appropriate transmission-based precautions✓ 正解實施適當之傳播途徑防護措施
- DObtain cultures for diagnostic testing採集培養物以供診斷檢測
在感染控制原則中，當懷疑病人有傳染性疾病時，預防病原體擴散至其他病人和醫護人員是首要任務。護理師應立即啟動標準防護措施（Standard Precautions）並根據疑似病原體的傳播途徑，採取相應的傳播途徑防護（Transmission-based Precautions，如空氣、飛沫或接觸防護），在確診前即執行防護措施是保護環境安全的最快行動。
In infection control principles, when a client is suspected of having an infectious disease, preventing the spread of the pathogen to other clients and health care workers is the first priority. The nurse should immediately initiate Standard Precautions and, based on the suspected pathogen's route of transmission, implement the appropriate transmission-based precautions (such as airborne, droplet, or contact precautions). Implementing protective measures before the diagnosis is confirmed is the fastest action to protect environmental safety.
