護理師準備無菌野以進行換藥，下列哪項動作顯示違反了無菌技術？
A nurse is preparing a sterile field for a dressing change. Which action indicates a break in sterile technique?
- AHolding sterile objects above waist level將無菌物品保持在腰部以上
- BOpening the outermost flap of the sterile kit away from the body將無菌套組最外層的摺頁朝遠離身體的方向打開
- CPlacing a sterile package on a wet surface✓ 正解將無菌包裝放置在潮濕表面上
- DKeeping the sterile field within the line of vision將無菌區域保持在視線範圍內
無菌技術（Sterile technique）的核心是確保無菌區（Sterile field）不被微生物污染。任何潮濕、破損或過期，甚至超出視線範圍的物品，均視為已被污染。潮濕表面會導致「毛細現象（Capillary action）」，讓細菌穿透無菌包裝進入內部。護理師必須嚴格遵守無菌原則，一旦懷疑無菌狀態受損，必須立即更換以確保病人安全。
The core of sterile technique is to ensure that the sterile field is not contaminated by microorganisms. Any item that is damp, damaged, expired, or out of the line of sight is regarded as contaminated. A wet surface produces capillary action, allowing bacteria to penetrate the sterile packaging into the interior. The nurse must strictly adhere to aseptic principles; once sterility is suspected to be compromised, the item must be replaced immediately to ensure patient safety.
