護理師照顧一位經尿道攝護腺切除術後使用持續性膀胱沖洗的病人。下列哪項評估結果需要立即處理？
A nurse is caring for a client with a continuous bladder irrigation system following a transurethral resection of the prostate. Which assessment finding requires immediate intervention?
- ABladder spasms noted during irrigation沖洗期間注意到膀胱痙攣
- BLight pink drainage in the urinary catheter泌尿道導尿管中有淡粉紅色引流液
- CAbsence of output from the catheter despite irrigation✓ 正解儘管持續沖洗，導尿管卻無引流液排出
- DClient reports a need to void around the catheter病人報告在導尿管周圍有排尿感
經尿道攝護腺切除術（TURP）術後進行持續性膀胱沖洗（CBI），目的是透過大量生理食鹽水沖洗，防止血塊堆積造成尿管阻塞。若沖洗液持續輸入但引流管無排出，代表引流系統發生阻塞，這會導致膀胱內壓迅速上升，引發劇烈膀胱痙攣，並可能導致膀胱破裂或大出血。護理師必須優先排除阻塞，以免造成致命併發症。臨床處理上，應立即檢查管路有無扭曲，並依醫囑進行手動沖洗（manual irrigation）以排除血塊。
Absence of output despite continuous irrigation indicates a blockage in the drainage system, which can rapidly increase intravesical pressure and risk bladder rupture or severe hemorrhage. This is a medical emergency requiring immediate assessment and manual irrigation to restore patency, whereas other findings like light pink drainage or spasms are expected or manageable complications.
