在進行傷口護理時，下列哪項動作顯示護理師確實遵守無菌原則？
When cleaning a client's wound, which action indicates the nurse is maintaining the principles of sterile technique?
- APlacing the sterile field below waist level將無菌區域置於腰部以下高度
- BReaching over the sterile field to pick up an item伸手越過無菌區域撿拾物品
- CCleaning the wound from the edges toward the center從傷口邊緣向中心清潔
- DOpening the outermost flap of the sterile package away from the body✓ 正解將無菌包最外層蓋片朝向遠離身體的方向打開
無菌技術原則：開啟無菌包裝時最後一層 flap 應遠離身體方向開啟（D）以避免手部跨越無菌區造成污染。其他選項：B. 越過無菌區會污染；B. 傷口清潔應從「中心向外」（cleanest 到 dirtiest），題目選項寫「從邊緣向中心」是錯誤方向；C. 無菌區須維持腰部以上，否則視為污染。
Sterile technique principles: when opening a sterile package, the last flap should be opened away from the body (D) to avoid crossing over the sterile field with the hand and causing contamination. The other options: A. crossing over the sterile field causes contamination; B. wound cleansing should proceed from center outward (cleanest to dirtiest), but the option states 'edge to center,' which is the wrong direction; C. the sterile field must be maintained above the waist; otherwise it is considered contaminated.
