Which of the following describes the correct procedure for emptying a urinary drainage bag?
- ARaise the bag above the bladder level將尿袋提高至高於膀胱水平
- BClean the spout with an alcohol swab before closing✓ 正解關閉前以酒精棉片清潔出水口
- CWear clean gloves戴清潔手套
- DLet the spout touch the collection container讓出水口接觸收集容器
排空尿袋涉及無菌技術（Aseptic Technique）的應用，目的是預防導尿管相關尿路感染（CAUTI）。排空時必須嚴格遵循感染控制原則：避免引流管出口（Spout）接觸到收集容器或地板，因為這些表面充滿微生物。排空後，使用酒精棉片清潔出口是為了消除殘留的尿液殘渣，防止細菌滋生。此外，尿袋必須始終低於膀胱高度，以利用重力原理防止尿液逆流，引發逆行性感染。
Emptying a urinary drainage bag involves the application of aseptic technique to prevent catheter-associated urinary tract infection (CAUTI). The nurse must strictly observe infection control principles during emptying: the drainage spout must not contact the collection container or the floor, because these surfaces harbor microorganisms. After emptying, the spout is cleaned with an alcohol swab to remove residual urine and prevent bacterial growth. In addition, the drainage bag must always be kept below the level of the bladder, so that gravity prevents backflow of urine and ascending infection.
