護理師照護一位進行膀胱連續沖洗（CBI）的病人，下列哪項為首要的安全考量？
A nurse is caring for a client with a continuous bladder irrigation (CBI) catheter. What is the priority safety concern?
- AMonitoring the client's electrolyte levels daily每日監測病人的電解質濃度
- BRecording the intake and output every 4 hours每 4 小時記錄出入量
- CEnsuring the irrigation fluid is warmed to body temperature確保灌洗液加熱至體溫
- DMaintaining continuous flow to prevent clot obstruction✓ 正解維持連續流動以防止血塊阻塞
膀胱連續沖洗（Continuous Bladder Irrigation, CBI）主要用於經尿道前列腺切除術（TURP）後，目的是稀釋尿液並防止凝血塊阻塞尿管。若管路阻塞，膀胱內壓會迅速升高，導致劇烈膀胱痙攣（Bladder spasms）、傷口出血加劇及尿滯留。維持沖洗液的連續流入與引流管路通暢，是預防併發症的首要安全任務。
Continuous bladder irrigation (CBI) is primarily used after transurethral resection of the prostate (TURP) to dilute urine and prevent clot obstruction of the catheter. If the tubing becomes obstructed, intravesical pressure rises rapidly, leading to severe bladder spasms, increased wound bleeding, and urinary retention. Maintaining continuous inflow of irrigation fluid and ensuring patency of the drainage tubing is the foremost safety priority for preventing complications.
在美國臨床，CBI 速度調整通常由護理師根據引流液顏色（如：維持在 Rose 或 Pink）依醫囑自動調整，不需頻繁呼叫醫師，這展現了護理師的自主權。
