下列哪些介入措施可預防導尿管相關泌尿道感染（CAUTI）？（選所有適合的）
Which of the following interventions prevents catheter-associated urinary tract infections (CAUTI)? (Select all that apply.)
- AKeep the drainage bag below the level of the bladder✓ 正解保持引流袋低於膀胱水平
- BUse sterile technique for insertion✓ 正解置管時使用無菌技術
- CSecure the catheter to the patient's leg✓ 正解將導尿管固定在病人腿上
- DChange the catheter daily每日更換導尿管
- EMaintain a closed drainage system✓ 正解維持封閉式引流系統
預防導尿管相關泌尿道感染（CAUTI）的關鍵在於維持無菌原則與管路封閉。導尿管應僅在必要時置入，並儘早拔除。日常照護重點包括：維持引流袋低於膀胱位置以防止尿液逆流（逆流會將細菌帶回膀胱）、保持封閉式系統（Closed system）以阻絕外界病原體、以及將管路妥善固定於大腿以減少尿道拉扯造成的黏膜損傷。
Preventing catheter-associated urinary tract infections (CAUTI) relies on maintaining aseptic principles and a closed drainage system. Catheters should be inserted only when necessary and removed as early as possible. Daily care priorities include keeping the drainage bag below bladder level to prevent reflux of urine (which would carry bacteria back into the bladder), maintaining a closed system to block external pathogens, and securing the tubing to the leg to reduce traction-related mucosal injury along the urethra.
