A client admitted for management of ulcerative colitis. Which sign would be of immediate concern?

• A. Tenesmus
• B. Hyperactive bowel sounds
• C. Ten bloody diarrhea stools in 8 hours
• D. Abdominal guarding

Answer: (D)

Abdominal guarding signals a potential surgical abdomen and peritoneal irritation, which in ulcerative colitis can indicate serious complications such as perforation or toxic megacolon. When the abdomen is guarded, the muscles tighten to protect the inflamed peritoneum, showing this is not a routine flare and requires urgent evaluation, imaging, and potentially surgical intervention.

Tenesmus is a common symptom of rectal irritation in UC but doesn’t by itself imply an emergency. Hyperactive bowel sounds can occur with inflammation but aren’t a definitive acute crisis. A rapid sequence of bloody stools reflects active inflammation and bleeding but doesn’t automatically indicate peritoneal catastrophe. Guarding, however, flags an urgent situation needing immediate assessment.
