護理師準備進行無菌傷口換藥，下列哪些行為符合外科無菌技術？（選所有適合的）
A nurse is preparing to perform a sterile dressing change. Which of the following actions maintains surgical asepsis? (Select all that apply.)
- AHolding sterile items above waist level✓ 正解將無菌物品保持在腰部以上高度。
- BTouching the edge of the sterile field with sterile gloves用無菌手套觸碰無菌區域的邊緣。
- COpening the outermost flap of a sterile kit away from the body✓ 正解將無菌包的最近層向外打開，遠離身體。
- DReaching over the sterile field to place items跨越無菌區域放置物品。
- EKeeping sterile objects within the 1-inch border of the field✓ 正解將無菌物品保持在區域邊緣1英寸範圍內。
外科無菌技術（Surgical Asepsis）要求在進行侵入性護理時，所有器材均需維持在無菌狀態。無菌區的邊緣 1 英寸被視為污染區（因為手可能在開包裝時觸碰），因此物品必須置於此範圍內。此外，無菌區若低於腰部則視為污染，因為護理師視線難以持續監控。打開滅菌包時，遠離身體的方向需先打開，以確保操作者的身體不會跨過無菌區。
Surgical asepsis requires that all equipment used during an invasive procedure be maintained in a sterile state. The 1-inch border at the edge of the sterile field is considered contaminated (because the hands may touch it while opening the packaging), so items must be placed within this boundary. In addition, the sterile field is considered contaminated if it falls below the waist, because the nurse cannot maintain continuous visual monitoring of it. When opening a sterile package, the flap farthest from the body should be opened first to ensure the operator's body does not cross over the sterile field.
