一位急診護理師剛為一名確診患有愛滋病與C型肝炎的病患抽完血。當護理師轉身準備丟棄針頭時，一名同事意外撞到她的手臂，導致裝滿血液的空心針頭深層刺穿了護理師的左手拇指。有明顯出血。根據 CDC 的暴露後處置常規，護理師必須採取的「第一步」立即處置為何？
An emergency department nurse finishes drawing blood from a patient firmly diagnosed with HIV and Hepatitis C. As the nurse turns to dispose of the needle, a coworker accidentally bumps her arm, causing the blood-filled hollow-bore needle to deeply puncture the nurse's left thumb. Bleeding is evident. According to the CDC's post-exposure protocol, what represents the immediate first action the nurse must take?
- ASqueeze the thumb forcefully and apply negative pressure using the mouth to suck out the inoculated blood.用力擠壓拇指並用嘴吸出負壓以吸出注入的血液
- BAlert the charge nurse and report to Employee Health immediately to initiate Post-Exposure Prophylaxis (PEP) within 10 minutes.立即通知值班護理師並向員工健康部門報告，以在10分鐘內啟動暴露後預防措施（PEP）
- CRemove the gloves and quickly wash the puncture site vigorously with soap and freely running water.✓ 正解摘下手套並迅速用肥皂和大量流動水用力清洗穿刺部位
- DImmediately scrub the puncture site with a concentrated hydrogen peroxide or bleach solution to kill the virus locally.立即用濃縮雙氧水或漂白水溶液擦洗穿刺部位以殺死局部病毒
本題測試血液傳染暴露後（Needlestick injury）的緊急標準操作程序。根據美國職業安全與健康管理局 (OSHA) 以及疾病管制中心 (CDC) 指引：當人員遭到尖銳物刺傷暴露時，最基礎且最優先的第一物理性反應是立刻脫下手套，並將傷口置於流動的清水與肥皂下進行物理性沖刷清洗（Wash the area with soap and water），這有助於利用水流阻斷病原繼續滲入（選項C正確）。選項A（掐擠與用嘴吸）是絕對禁忌，這不但破壞組織，口腔黏膜反而可能成為二次暴露且更快吸收病毒的破口。選項D使用強酸、強鹼或苛性消毒劑（如漂白水）亦為禁忌，這會破壞真皮層屏障，反而加速病毒入侵血液。雖然啟動暴露後預防（PEP）非常重要（選項B），但這是在清洗傷口的物理急救完成之後才執行的回報與醫療程序。
Immediate first aid for a needlestick injury involves removing gloves and vigorously washing the puncture site with soap and running water to mechanically remove contaminants. Oral suction and caustic agents like bleach are contraindicated as they increase infection risk or damage tissue, while PEP initiation follows this initial cleaning step.
台美在針扎事件的第一步處理「肥皂水清洗」完全吻合，也是兩國執照考年年必考的核心概念。台灣的流程通報為感染管制室並走 HIV PEP （暴露後預防）黃金兩小時途徑，完全對接美國標準。
