Medical Surgical Celiac disease #4

Question

Which diagnostic test does the nurse expect to confirm celiac disease in a client?

Answers

  1. CT exam
    • Rationale:

      This answer is not correct because a CT exam is not necessary and will not produce the information needed to confirm celiac disease in a client. A biopsy of the small intestines confirms the diagnosis of celiac disease.

  2. Schilling test
    • Rationale:

      This answer is not correct because a Schilling test is used to tell if a person is able to absorb B-12 adequately. This is used when a healthcare provider suspects a client has vitamin B-12 deficiency or pernicious anemia.

  3. Biopsy of intestines
    • Rationale:

      This answer is correct because a biopsy of the small intestines confirms the diagnosis of celiac disease. This is done by an endoscopic examination, under anesthesia.

  4. Helicobacter pylori test
    • Rationale:

      This answer is not correct because Helicobacter pylori is a bacteria that can be found in the stomach. It can infect the stomach and cause peptic ulcer disease and cancer in some individuals. Helicobacter pylori does not cause celiac disease.

Overview

A biopsy of the small intestines confirms the diagnosis of celiac disease. Endoscopy of the duodenal and small intestines biopsy can confirm the diagnosis of celiac disease.

Explanation

Learning Outcomes

Celiac disease is a condition where the body builds an immune reaction to gluten. This reaction causes inflammation and damages the small intestines. A biopsy of the small intestines confirms the diagnosis of celiac disease. Damage to the small intestines from celiac disease causes malabsorption of some nutrients. Common symptoms of celiac disease are chronic foamy, fatty diarrhea (steatorrhea), abdominal cramping, pain, gas, fatigue, and anemia. The main treatment of celiac disease is strict avoidance of gluten-containing foods. Foods containing gluten include rye, barley, oats, and wheat so the client should avoid these foods.

Test Taking Tip

It is important to understand the pathophysiology of celiac disease, the role of gluten, and what happens to cause malabsorption. It is not related to B-12 malabsorption or a bacteria, such as Helicobacter pylori.
