護理師準備給予病人靜脈注射抗生素，哪項措施對預防導管相關血流感染（CRBSI）至關重要？
A nurse is preparing to administer an intravenous antibiotic to a client. Which action is crucial for preventing a catheter-related bloodstream infection (CRBSI)?
- AUsing sterile gloves during insertion of the IV catheter.✓ 正解置入靜脈導管時使用無菌手套
- BChanging the IV dressing every 48 hours.每 48 小時更換靜脈導管敷料
- CFlushing the IV line with normal saline before and after administration.給藥前後以生理食鹽水沖洗靜脈管路
- DAdministering the antibiotic over the prescribed time frame.在規定時間內給予抗生素
預防導管相關血流感染（CRBSI）的核心是置入時的無菌技術。對於周邊靜脈導管（PIV），CDC 建議使用 clean gloves 配合 no-touch aseptic technique；對於中央靜脈或 PICC，則需 maximal sterile barrier（口罩、帽子、無菌手套、無菌袍與大型無菌洞巾）。本題未明確指出導管類型，A（無菌技術）涵蓋了所有層級導管的核心原則，是現有選項中最佳答案。其他選項：C 沖洗維持通暢但非感染預防主軸；C 給藥時間影響療效非感染；D 敷料更換頻率為持續預防而非置入當下的關鍵步驟。
Using sterile gloves during insertion is crucial because aseptic technique is the cornerstone of preventing catheter-related bloodstream infections. While dressing changes and flushing maintain line integrity, proper sterile handling at the time of insertion provides the primary defense against introducing pathogens.
無顯著差異。預防導管相關血流感染（CRBSI）的原則在全球醫療體系中均為一致，強調無菌技術、正確的導管置入與照護、以及適當的消毒措施。台灣的醫療機構與美國一樣，都遵循 CDC 或相關感染管制指引來執行。
