護理師準備為病人靜脈給予抗生素，哪項行動對於預防全身性感染最為關鍵？
A nurse is preparing to administer an intravenous antibiotic to a client. Which action is the most critical for preventing systemic infection?
- AChecking the expiration date of the medication檢查藥品的有效期限
- BCalculating the dosage according to the client's weight根據客戶體重計算劑量
- CVerifying the client's identity using two identifiers使用兩種識別方式驗證客戶身份
- DScrubbing the infusion port with an antiseptic agent for at least 15 seconds✓ 正解使用消毒劑摩擦輸注端口至少15秒

預防導管相關血液感染（CRBSI）的核心在於無菌操作。摩擦消毒連接埠（Hub/Port）能機械性清除微生物，是防禦細菌進入血流的最直接屏障。其他選項雖為給藥安全規範，但與降低感染風險的關聯性不如物理消毒顯著。
Scrubbing the infusion port with an antiseptic agent for at least 15 seconds is the most critical action for preventing systemic infection, as friction mechanically removes pathogens. While checking expiration dates, calculating dosages, and verifying identity are essential for medication safety, they do not directly prevent microbial entry into the bloodstream.
✦ 台美臨床差異
台灣醫院多強調使用酒精片消毒，美國則極度重視「摩擦（Scrub the hub）」這一機械動作的時長與力度。
