哪項護理行動能降低尿管病人的泌尿道感染風險？
Which nursing action reduces the risk of urinary tract infection in a patient with a catheter?
- AOpen the drainage system to measure urine打開引流系統以測量尿量
- BKeep the drainage bag below the level of the bladder✓ 正解保持引流袋低於膀胱水平
- CIrrigate the catheter daily每日沖洗導尿管
- DTape the catheter to the side rail將導尿管固定於床欄
留置導尿管是導致醫源性泌尿道感染（CAUTI）的主要因素。護理重點在於維持封閉系統（Closed system）的完整性。尿袋必須保持在膀胱水平以下，利用地心引力防止含有細菌的尿液逆流回膀胱。臨床上，每日評估導尿管的必要性（Catheter-associated UTI prevention bundles）是減少感染最有效的策略。
Indwelling urinary catheters are the leading cause of healthcare-associated UTIs (CAUTI). The cornerstone of prevention is maintaining a closed drainage system and keeping the collection bag below bladder level so that gravity prevents backflow of contaminated urine into the bladder. Routine irrigation, opening the system, and securing the catheter to the side rail all increase infection or injury risk. CDC CAUTI bundles also emphasize daily assessment of catheter necessity and prompt removal.
