護理師準備對手術傷口進行無菌換藥。下列哪項措施能維持手術無菌技術？
A nurse is preparing to perform a sterile dressing change on a patient with a surgical incision. Which action by the nurse maintains surgical asepsis?
- AKeep the sterile field above waist level✓ 正解保持無菌區域在腰部以上
- BUse sterile gloves to open the sterile kit使用無菌手套開啟無菌包
- CPlace sterile items 1 inch from the edge of the sterile field將無菌物品放置在無菌區域邊緣1英吋處
- DOpen the outermost flap of the sterile kit toward the body朝向身體方向開啟無菌包的最外層蓋子
無菌技術（Surgical Asepsis）的執行是防止手術部位感染（SSI）的關鍵。無菌區的維持原則包括：無菌物品必須在腰部以上、無菌包裝邊緣 1 英吋（約 2.5 公分）視為污染區、不可背對無菌區、不可跨越無菌區，以及避免水分滲透無菌鋪單（Strike-through）。任何疑似被污染的區域都應視為不潔並立即更換。
Surgical asepsis is essential to preventing surgical site infection (SSI). Key principles for maintaining the sterile field include keeping sterile items above waist level, considering the 1-inch (about 2.5 cm) border of a sterile package as contaminated, never turning the back to the sterile field, never reaching across the field, and avoiding strike-through (moisture penetrating the sterile drape). Any area suspected of contamination should be treated as non-sterile and replaced immediately.
