Which observation by the nurse best indicates that a continuous bladder irrigation for a patient following genitourinary surgery is effective?

Choice A reason: Bladder distention with tenderness indicates ineffective irrigation, suggesting obstruction or inadequate fluid flow. Continuous bladder irrigation (CBI) aims to maintain bladder patency and prevent clot formation. Distention reflects urine or clot accumulation, potentially leading to bladder injury or infection, requiring immediate intervention. Choice B reason: Blood clots or sediment in the drainage bag suggest inadequate irrigation. CBI is designed to flush out clots and debris post-surgery to prevent obstruction. Persistent clots indicate the irrigation fluid is not effectively clearing the bladder, increasing risks of catheter blockage and urinary complications. Choice C reason: Bright red urine turning pink indicates effective CBI. Initially, hematuria is common post-genitourinary surgery, but a lighter color suggests the irrigation is diluting blood and clearing clots, maintaining catheter patency and promoting healing by reducing bladder irritation and obstruction risks. Choice D reason: Output smaller than the instilled amount suggests fluid retention or leakage, indicating ineffective irrigation. CBI requires output to equal or exceed input to ensure bladder flushing and catheter patency. Reduced output may signal obstruction or absorption, risking bladder overdistention or systemic fluid imbalance.
