護理師觀察輔助人員（AP）照護病人。下列哪項動作需要護理師立即介入？
A nurse is observing an assistive personnel (AP) providing care. Which action by the AP requires immediate intervention?
- ARemoving gloves and then immediately performing hand hygiene脫除手套後立即執行手部衛生
- BWiping a blood spill with a paper towel and disinfectant用紙巾和消毒劑擦拭血漬
- CWearing gloves when providing a bed bath提供床浴時戴手套
- DRecapping a contaminated needle after patient care✓ 正解病人照護後重新套上受污染針頭的護套
回套針頭（Recapping a used needle）是被嚴格禁止的臨床行為，因為這極大增加了針扎（Needlestick injury）的風險，進而可能導致 HIV、B型肝炎（HBV）及 C型肝炎（HCV）等血源性病原體的職業暴露。根據 OSHA（職業安全與健康管理局）標準，使用過的針頭應直接投入防穿刺的銳器盒（Sharps container）。
Recapping a used needle is a strictly prohibited clinical behavior, because it greatly increases the risk of needlestick injury, which can lead to occupational exposure to blood-borne pathogens such as HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV). According to OSHA (Occupational Safety and Health Administration) standards, used needles must be disposed of directly into a puncture-resistant sharps container.
在美國，這類行為一旦被稽核發現，不僅會導致嚴重的懲處，還會被列入醫院的 Incident Report（意外報告）系統。美國醫院對銳器安全（Needleless systems）的要求極高，幾乎已全面推廣安全針頭裝置，若違規使用舊式針頭回套，護理師會面臨極大的資方與法規壓力。
