A nurse is explaining to a group of students how chronic inflammation in Inflammatory Bowel Disease (IBD) leads to tissue damage. What is a key mechanism involved in this process?
Formation of scar tissue (fibrosis)
Increased production of digestive enzymes
Accelerated cell regeneration in the intestines
Strengthening of intestinal mucosa
The Correct Answer is A
A) Correct. Chronic inflammation in Inflammatory Bowel Disease can lead to the formation of scar tissue (fibrosis) in the intestines. This can result in narrowing of the intestinal lumen and obstruction.
B) Incorrect. While increased production of digestive enzymes may occur in certain digestive disorders, it is not a primary mechanism involved in the tissue damage seen in IBD.
C) Incorrect. In IBD, cell regeneration is often disrupted, and accelerated cell turnover can contribute to inflammation and tissue damage rather than healing.
D) Incorrect. In IBD, the intestinal mucosa may be weakened rather than strengthened due to chronic inflammation and damage.

Correct Answer is C
Explanation
A) Incorrect. Older age (60+) is not typically associated with an increased risk of developing Inflammatory Bowel Disease. IBD can affect individuals of various age groups.
B) Incorrect. In terms of gender, both males and females are susceptible to Inflammatory Bowel Disease. It does not predominantly affect one gender over the other.
C) Correct. Caucasian ethnicity is associated with a higher risk of developing Inflammatory Bowel Disease. It is more commonly diagnosed in individuals of Caucasian descent.
D) Incorrect. While socioeconomic status can impact access to healthcare and management of chronic conditions, it is not a direct demographic factor associated with an increased risk of IBD.
Correct Answer is B
Explanation
Rationale
A) Incorrect. In IBD, the immune system is actually overactive, leading to chronic inflammation rather than being underactive.
B) Correct. In Inflammatory Bowel Disease, the immune system mistakenly identifies the body's own intestinal tissues as foreign invaders and launches an inflammatory response against them. This is known as an autoimmune response.
C) Incorrect. The immune system plays a central role in the development and progression of Inflammatory Bowel Disease. It is not uninvolved.
D) Incorrect. While the immune system is active in Inflammatory Bowel Disease, its focus is not solely on fighting infections. It is also targeting the body's own intestinal tissues due to a misdirected immune response.
