護理師準備為病人執行注射。為了預防針扎傷害，哪項行動最重要？
A nurse is preparing to administer an injection to a client. Which action is the most important for preventing needlestick injuries?
- AWearing double gloves戴雙層手套
- BAsking another nurse to hold the client請另一位護理師協助固定病人
- CRecapping the needle immediately after use使用後立即回套針蓋
- DDisposing of the needle directly into a sharps container✓ 正解將針頭直接丟入銳器盒
針扎傷害（Needlestick injury）是醫療人員職業暴露的主要來源。根據標準防護原則（Standard Precautions），預防針扎最有效的策略就是「消除危險源」。針頭在注射後應立即丟入銳器盒（Sharps container），絕對禁止回套（Recapping），因為回套過程是發生針扎的高風險點。
To prevent needlestick injuries, the most critical action is disposing of the needle directly into a sharps container immediately after use. Recapping needles is prohibited as it is a leading cause of accidental punctures, and double gloves do not prevent needle penetration. Eliminating unnecessary handling of sharp objects minimizes exposure risk.
美國醫院有嚴格的 OSHA（職業安全衛生署）規範，強制要求使用具備安全裝置（Safety-engineered devices）的針頭。台灣臨床上雖然也提倡不回套，但美國對於銳器盒的放置位置與安全裝置的使用普及率要求更為嚴苛。
