ARRT Patient Care Practice Exam

Which of the following are types of inflammatory bowel disease?

1. Ulcerative colitis only

2. Ulcerative colitis and Crohn's disease only

3. Crohn's disease and intussusception only

4. Ulcerative colitis, Crohn's disease, and intussusception

The correct answer is: Crohn's disease and intussusception only

The question focuses on identifying types of inflammatory bowel disease (IBD). Inflammatory bowel disease primarily includes two main conditions: ulcerative colitis and Crohn's disease. Both of these conditions are characterized by chronic inflammation of the gastrointestinal tract, with ulcerative colitis typically affecting the colon and rectum, while Crohn's disease can affect any part of the gastrointestinal tract from the mouth to the anus. Intussusception, on the other hand, is a condition where a part of the intestine telescopes into an adjacent segment, which can lead to obstruction, but it is not classified as an inflammatory bowel disease. It is more of a mechanical issue and can occur as a separate clinical condition. Therefore, the correct identification of inflammatory bowel diseases is limited to ulcerative colitis and Crohn's disease. Thus, options that include intussusception do not accurately reflect the types of inflammatory bowel disease. This distinction emphasizes the specific nature of inflammatory bowel diseases and helps clarify the correct answer, which accurately recognizes the two predominant conditions without including unrelated conditions.
