護理師照顧放置留置導尿管的病人，預防導尿管相關尿路感染（CAUTI）最關鍵的措施為何？
A nurse is caring for a client with a urinary catheter. Which nursing action is essential to prevent a catheter-associated urinary tract infection (CAUTI)?
- AKeep the drainage bag below the level of the bladder✓ 正解保持引流袋低於膀胱水平
- BDisconnect the catheter frequently to check for blockage經常斷開導尿管以檢查是否有阻塞
- CApply antibiotic ointment to the meatus daily每日在尿道口塗抹抗生素軟膏
- DIrrigate the catheter with saline every 4 hours每4小時以生理食鹽水沖洗導尿管

預防 CAUTI 最重要原則為維持尿路系統的封閉性與正確引流。將收集袋保持在膀胱水平以下是利用重力引流防止尿液逆流，逆流會將膀胱底部的細菌帶回。灌洗或斷開導管會增加病原體進入風險；抗生素藥膏則可能導致抗藥性與細菌滋生。
Preventing catheter-associated urinary tract infections requires maintaining a closed drainage system and ensuring proper gravity drainage. Keeping the collection bag below the level of the bladder prevents urine backflow, which can introduce bacteria from the bag into the bladder. Disconnecting the catheter or performing routine irrigation increases the risk of introducing pathogens.
