1. If a client had irritable bowel syndrome, which of the following diagnostic tests would determine if the diagnosis is Crohn’s disease or ulcerative colitis?

• A. Abdominal computed tomography (CT) scan
• B. Abdominal x-ray
• C. Barium swallow
• D. Colonoscopy with biopsy

Correct answer: D

Rationale: A colonoscopy with biopsy is the most definitive diagnostic test to differentiate between Crohn's disease and ulcerative colitis.

2. Which of the following definitions best describes diverticulosis?

• A. An inflamed outpouching of the intestine
• B. A noninflamed outpouching of the intestine
• C. The partial impairment of the forward flow of intestinal contents
• D. An abnormal protrusion of an organ through the structure that usually holds it

Correct answer: B

Rationale: The correct answer is B: 'A noninflamed outpouching of the intestine.' Diverticulosis refers to the presence of small, bulging pouches (diverticula) that can form in the lining of the digestive system, especially the colon. These pouches are typically noninflamed. Choice A is incorrect because it describes diverticulitis, which is the inflammation of these pouches. Choice C is incorrect as it defines bowel obstruction, not diverticulosis. Choice D is incorrect as it refers to a hernia, not diverticulosis.

3. A patient with Crohn’s disease is admitted after 4 days of diarrhea. Which of the following urine specific gravity values do you expect to find in this patient?

• A. 1.005
• B. 1.011
• C. 1.02
• D. 1.03

Correct answer: D

Rationale: A urine specific gravity of 1.030 indicates concentrated urine, which is expected in a patient with dehydration due to diarrhea from Crohn’s disease.

4. Kevin has a history of peptic ulcer disease and vomits coffee-ground emesis. What does this indicate?

• A. He has fresh, active upper GI bleeding.
• B. He needs immediate saline gastric lavage.
• C. His gastric bleeding occurred 2 hours earlier.
• D. He needs a transfusion of packed RBCs.

Correct answer: C

Rationale: Coffee-ground emesis is a sign of upper gastrointestinal bleeding that occurred approximately 2 hours earlier. It results from the breakdown of blood in the stomach due to digestive enzymes, giving it a coffee-ground appearance. Choice A is incorrect because coffee-ground emesis indicates older, partially digested blood, not fresh active bleeding. Choice B is incorrect as gastric lavage is not indicated for coffee-ground emesis. Choice D is incorrect because a transfusion of packed RBCs is not the immediate management for this presentation.

5. Radiation therapy is used to treat colon cancer before surgery for which of the following reasons?

• A. Reducing the size of the tumor
• B. Eliminating the malignant cells
• C. Curing the cancer
• D. Helping the bowel heal after surgery

Correct answer: A

Rationale: Radiation therapy is used before surgery to reduce the size of the tumor, making it easier to remove.
