A client with Inflammatory Bowel Disease (IBD) asks the nurse about the underlying cause of their condition. How should the nurse respond?

A.

"IBD is primarily caused by bacterial infections in the gastrointestinal tract."

B.

"The exact cause of IBD is unknown, but it involves an abnormal immune response in the intestines."

C.

"IBD is caused by excessive stress and emotional factors."

D.

"IBD is a genetic disorder inherited from one's parents."

Answer and Explanation

The Correct Answer is B

A) Incorrect. While bacterial infections can play a role in the exacerbation of IBD symptoms, they are not considered the primary cause of the condition.

B) Correct. The exact cause of Inflammatory Bowel Disease is not fully understood, but it is believed to involve a combination of genetic, environmental, and immune factors. An abnormal immune response in the intestines plays a significant role in the development of IBD.

C) Incorrect. While stress and emotional factors can impact the severity of IBD symptoms, they are not the underlying cause of the condition.

D) Incorrect. While there may be a genetic component to IBD, it is not solely a genetic disorder inherited from parents. It involves a complex interplay of genetic and environmental factors.

Correct Answer is A

Explanation

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 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.
