The nurse is caring for a client diagnosed with Crohn's disease who just returned from surgery for a placement of a permanent colostomy. Which assessment finding requires immediate intervention?

Postoperative care of a client with a new permanent colostomy after surgery for Crohn’s disease focuses on early identification of complications related to stoma viability and gastrointestinal recovery. After colostomy formation, the stoma should be assessed for color, moisture, perfusion, output, and protrusion above the skin level. Adequate blood supply and proper positioning are critical indicators of healthy tissue perfusion. Any deviation suggesting ischemia or poor surgical outcome requires immediate attention. A. A stoma that is at the level of the abdomen or flush with the skin suggests possible retraction or compromised surgical positioning. A healthy stoma should be moist, pink to red, and slightly protruding above skin level to ensure adequate perfusion and proper effluent drainage. A flat or recessed stoma increases risk of leakage, skin breakdown, and ischemia, requiring immediate intervention to prevent necrosis. B. Absence of bowel sounds is expected in the immediate postoperative period due to anesthesia and temporary paralytic ileus following bowel surgery. The gastrointestinal tract typically requires time to regain peristaltic activity. While continued monitoring is necessary, this finding alone does not indicate an acute complication requiring immediate intervention. C. Mild tenderness at the stoma site is expected following surgical creation of a colostomy due to tissue manipulation and inflammation. Postoperative discomfort should gradually decrease as healing progresses. As long as pain is controlled and there are no signs of infection or ischemia, this finding is considered within normal postoperative expectations. D. Absence of stool drainage immediately after colostomy surgery is expected because bowel function takes time to resume. The return of peristalsis varies depending on the location of the colostomy and postoperative recovery. Delayed output alone is not alarming unless accompanied by signs of obstruction, severe distention, or systemic instability.
