護理師照護一位留置導尿管的病人。下列哪項措施能有效預防導尿管相關泌尿道感染 (CAUTI)？
A nurse is caring for a client with a urinary catheter. Which action is appropriate to prevent a catheter-associated urinary tract infection (CAUTI)?
- AKeeping the drainage bag below the level of the bladder✓ 正解保持引流袋低於膀胱水平
- BEmptying the drainage bag when it is completely full待引流袋完全充滿時再排放
- CSecuring the catheter tubing to the client's upper thigh at all times始終將導尿管管路固定在病人大腿上部
- DIrrigating the catheter daily with sterile water每日以無菌水沖洗導尿管
預防導尿管相關泌尿道感染（CAUTI）的核心在於維持封閉式引流系統（closed drainage system）的無菌性。細菌常透過引流管逆行進入膀胱，因此重力引流至關重要。保持引流袋低於膀胱水平可防止尿液因重力倒流（reflux），這是預防感染最有效且基本的物理屏障。護理措施應聚焦於減少導管留置時間、維持系統封閉及確保引流暢通。
Preventing catheter-associated urinary tract infection (CAUTI) centers on maintaining the sterility of the closed drainage system. Bacteria often ascend retrograde through the drainage tubing into the bladder, so gravity drainage is essential. Keeping the drainage bag below the level of the bladder prevents urine reflux due to gravity and is the most effective and basic physical barrier for preventing infection. Nursing measures should focus on reducing catheter dwell time, maintaining a closed system, and ensuring patent drainage.
