A nurse is caring for a client who has ulcerative colitis and is teaching the client about the common link with Crohn's disease. Which of the following information should the nurse include?

Rationale: A. Ulcerative colitis always begins in the rectum and progresses proximally, but Crohn’s disease can occur anywhere in the GI tract. B. Ulcerative colitis and Crohn’s disease are both types of inflammatory bowel disease (IBD) characterized by chronic intestinal inflammation. C. Surgery may be needed in severe cases, but ulcerative colitis can sometimes be cured with colectomy, while Crohn’s disease is not cured by surgery and tends to recur. D. Fistulas are common in Crohn’s disease but not in ulcerative colitis.
