護理師照顧一位經尿道攝護腺切除術（TURP）後進行持續膀胱沖洗的病人，下列哪項結果顯示需要介入？

核心概念：經尿道攝護腺切除術（Transurethral Resection of the Prostate, TURP）後的持續膀胱沖洗（Continuous Bladder Irrigation, CBI）護理。 為何正確答案對： C. TURP 手術後，膀胱內可能殘留血塊，CBI 的目的是透過沖洗液將這些血塊沖出，維持尿道暢通。若灌洗液的輸出量（Output）顯著少於輸入量（Input），表示引流管路可能被血塊或組織碎片阻塞，導致尿液無法順利排出。此情況可能引起膀胱過度脹大、劇烈疼痛，甚至膀胱破裂，是需要立即處理的緊急情況。 為何其他選項錯： A. 尿液呈現粉紅色（Pink-tinged urine）是 TURP 術後常見現象，表示有少量出血，屬於正常範圍，無需立即干預。 B. 病人主訴膀胱痙攣（Bladder spasms）是 TURP 術後常見的不適，通常可透過調整沖洗液流速、給予抗痙攣藥物（如 Oxybutynin）來緩解，不一定需要立即醫療介入，除非痙攣劇烈且影響引流。 D. 輸尿管管路中出現小血塊（Small blood clots）也是 TURP 術後常見的，只要引流順暢，通常無需立即處理，可透過持續沖洗排除。

Core concept: nursing care for continuous bladder irrigation (CBI) following transurethral resection of the prostate (TURP). Why the correct answer is right: C. Following TURP, blood clots may remain in the bladder; the purpose of CBI is to flush these clots out through the irrigation fluid and maintain urinary patency. If the irrigation output is significantly less than the input, the drainage tubing may be obstructed by clots or tissue debris, preventing urine outflow. This can lead to bladder over-distention, severe pain, and even bladder rupture — a true emergency requiring immediate intervention. Why the other options are wrong: A. Pink-tinged urine is a common finding after TURP, reflecting small amounts of bleeding, and is within the expected range, requiring no immediate intervention. B. Bladder spasms are a common discomfort after TURP and can usually be relieved by adjusting the irrigation flow rate or administering antispasmodics (e.g., oxybutynin); they do not necessarily require immediate medical intervention unless they are severe and impede drainage. D. Small blood clots in the urinary tubing are also common after TURP and, as long as drainage remains adequate, typically require no immediate intervention since they can be removed through continued irrigation.
