Which clinical manifestations does the nurse expect to find on the assessment of client diagnosed with an acute exacerbation of ulcerative colitis?

Ulcerative colitis is a chronic inflammatory bowel disease characterized by continuous inflammation of the colonic mucosa, typically beginning in the rectum and extending proximally. During an acute exacerbation, inflammation leads to ulceration of the intestinal lining, resulting in frequent bowel movements, abdominal cramping, urgency, and passage of blood and mucus in the stool. The severity of symptoms depends on the extent and activity of the inflammatory process. Nursing assessment focuses on identifying signs of active colonic inflammation and systemic involvement. A. Frequent bloody stools are a hallmark manifestation of an acute exacerbation of Ulcerative colitis. Active mucosal inflammation leads to ulceration and capillary fragility, causing rectal bleeding and increased stool frequency. Having multiple bloody stools per day reflects disease severity and ongoing colonic inflammation, which is expected during flare-ups. B. An elevated temperature such as 101.4°F may occur in severe inflammatory or infectious processes but is not a defining or most characteristic manifestation of an acute flare of Ulcerative colitis. Fever may suggest systemic involvement or complications, but the primary and most consistent clinical feature remains bloody diarrhea and urgency. C. Urinary stress incontinence is not associated with an acute exacerbation of Ulcerative colitis. This symptom is related to pelvic floor dysfunction or urologic conditions rather than inflammatory changes in the colon. It is not expected as part of the disease process. D. A hard, rigid abdomen suggests peritonitis or possible bowel perforation, which are severe complications rather than typical findings of an uncomplicated ulcerative colitis flare. In Ulcerative colitis, the abdomen is more commonly tender and crampy rather than rigid. A rigid abdomen would indicate an emergency rather than routine exacerbation.
