  1. How does celiac disease cause malabsorption?
    • A. Injury to the small bowel causes loss of absorptive surface area, a decrease in digestive enzymes, and inflammation, which causes fluid secretion.
    • B. Gluten is not directly metabolized by small bowel brush border, which causes fluid secretion and subsequent osmotic diarrhea.
    • C. Excess gluten exposure in the small bowel leads to abdominal cramping, bloating, and subsequent overflow diarrhea.
    • D. Gluten is not absorbed in the small bowel so it binds to other nutrients, which causes malabsorption of carbohydrates, vitamins, and minerals.
  2. In addition to celiac disease, which one of the following groups of disorders, conditions, or treatments are associated with lymphocytic duodenosis?
    • A. Fecal microbiota transplantation and prokinetics
    • B. Irritable bowel syndrome and Heyde's syndrome
    • C. Helicobacter pylori infection and small-bowel bacterial overgrowth
    • D. Fructose intolerance and pregnancy
  3. Patients with celiac disease are at an increased risk for which type of malignancies?
    • A. Colorectal cancer, testicular cancer, and ovarian cancer
    • B. Small bowel adenocarcinoma, B-cell and T-cell non-Hodgkin lymphomas, and esophageal cancer
    • C. Small bowel sarcoma, melanoma, and retinoblastoma
    • D. Gastric adenocarcinoma, gastric lymphoma, and duodenal sarcoma
