Nursing Elites

1. Which of the following best describes the method of action of medications, such as ranitidine (Zantac), which are used in the treatment of peptic ulcer disease?

• A. Neutralize acid
• B. Reduce acid secretions
• C. Stimulate gastrin release
• D. Protect the mucosal barrier

Correct answer: B

Rationale: Medications like ranitidine (Zantac) are H2 receptor antagonists that reduce acid secretions in the stomach, helping to treat peptic ulcer disease.

2. 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.

3. The nurse is scheduling diagnostic tests for a client. If all of the following diagnostic tests are ordered, which would be performed last?

• A. Gallbladder series
• B. Barium enema
• C. Barium swallow
• D. Oral cholecystogram

Correct answer: C

Rationale: The correct answer is C, 'Barium swallow.' A barium swallow should be done after a barium enema or gallbladder series to prevent the contrast used in the barium swallow from obstructing the view of other organs. It takes several days for swallowed barium to pass completely out of the gastrointestinal tract. Choices A, B, and D are incorrect because a barium swallow should be the last test performed to ensure clear imaging without interference from residual contrast material.

4. You are developing a careplan on Sally, a 67 y.o. patient with hepatic encephalopathy. Which of the following do you include?

• A. Administering a lactulose enema as ordered.
• B. Encouraging a protein-rich diet.
• C. Administering sedatives, as necessary.
• D. Encouraging ambulation at least four times a day.

Correct answer: A

Rationale: Administering a lactulose enema as ordered helps reduce ammonia levels in patients with hepatic encephalopathy.

5. Of the following signs and symptoms of bowel obstruction, which is related primarily to small bowel obstruction rather than large bowel obstruction?

• A. Profuse vomiting.
• B. Cramping abdominal pain.
• C. Abdominal distention.
• D. High-pitched bowel sounds above the obstruction.

Correct answer: A

Rationale: Profuse vomiting is the classic sign of small bowel obstruction and rarely occurs with large bowel obstruction. Abdominal discomfort and distention are present in both small and large bowel obstructions, but distention is more common in large bowel obstruction. High-pitched bowel sounds indicate hyperperistalsis, which occurs early in obstruction.
