護理師準備為病人給予靜脈注射抗生素。下列哪項措施對於降低全身性感染風險最為重要？
A nurse is preparing to administer an intravenous antibiotic to a client. Which action is most important to reduce the risk of systemic infection?
- AVerify the medication with another nurse由另一位護理師核對藥物
- BPerform hand hygiene before handling the infusion system✓ 正解在處理輸液系統前執行手部衛生
- CAssess the IV site for signs of phlebitis評估靜脈注射部位是否有靜脈炎的跡象
- DCheck the client's allergy history檢查個案的過敏史
降低導管相關血液感染（CRBSI）的核心在於預防微生物進入循環系統。手部衛生是感染控制的第一道防線，也是最有效、最經濟的預防手段。雖然過敏史核對與確認藥物屬病人安全範疇，評估靜脈炎則是局部評估，執行無菌操作前的洗手對預防全身性感染最具直接影響力。
Reducing catheter-related bloodstream infections (CRBSI) centers on preventing microorganisms from entering the circulatory system. Hand hygiene is the first line of defense in infection control and is the most effective and least costly preventive measure. Although verifying allergy history and confirming medications relate to client safety and assessing for phlebitis is a local evaluation, hand washing before performing aseptic procedures has the most direct effect on preventing systemic infection.
台美醫療機構均嚴格執行 WHO 的洗手五時刻，美國於導管維護流程中對於無菌技術的要求非常高且有稽核制度。
