A client with bladder cancer had surgical placement of a ureteroileostomy (ileal conduit) yesterday. Which postoperative assessment finding should the nurse report to the healthcare provider immediately?

Rationale: A. Red edematous stomal appearance: A bright red, moist, and mildly edematous stoma is expected in the immediate postoperative period. These features indicate healthy perfusion and normal healing after surgery. B. Stomal output of 40 mL in last hour: This is a normal output volume for a ureteroileostomy. Urine flows continuously in small amounts, and 30–60 mL per hour is considered within normal limits for adequate renal function. C. Liquid brown drainage from stoma: Brown liquid drainage suggests fecal contamination or leakage from the bowel, which is abnormal in a urinary diversion and may indicate a serious complication such as bowel injury or fistula formation. This requires urgent evaluation. D. Mucous strings floating in the drainage: Mucus production from the ileal segment is expected because intestinal mucosa continues to secrete mucus even after being repurposed as a urinary conduit. This finding is not concerning.
