Nursing Elites

1. Lactulose (Chronulac) is prescribed for a client with a diagnosis of hepatic encephalopathy. The nurse would determine that this medication has had a therapeutic effect if which of the following is noted?

• A. Increased red blood cell count
• B. Decreased serum ammonia level
• C. Increased protein level
• D. Decreased white blood cell level

Correct answer: B

Rationale: Lactulose is prescribed for the client with hepatic encephalopathy to reduce bacterial breakdown of protein in the bowel. The medication creates an acidic environment in the bowel and causes the ammonia to leave the bloodstream and enter the colon. Ammonia then becomes trapped in the bowel. Lactulose also has a laxative effect that allows for the elimination of the ammonia.

2. 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.

3. The nurse is caring for a client who underwent a subtotal gastrectomy. To manage dumping syndrome, the nurse should advise the client to:

• A. restrict fluid intake to 1 qt (1,000 ml)/day.
• B. drink liquids only with meals.
• C. don't drink liquids 2 hours before meals.
• D. drink liquids only between meals.

Correct answer: D

Rationale: A client who experiences dumping syndrome after a subtotal gastrectomy should be advised to ingest liquids between meals rather than with meals. Taking fluids between meals allows for adequate hydration, reduces the amount of bulk ingested with meals, and aids in preventing rapid gastric emptying. There is no need to restrict the amount of fluids, just the time when the client drinks fluids. Drinking liquids with meals increases the risk of dumping syndrome by increasing the amount of bulk and stimulating rapid gastric emptying. Small amounts of water are allowable before meals.

4. Your patient has a retractable gastric peptic ulcer and has had a gastric vagotomy. Which factor increases as a result of vagotomy?

• A. Peristalsis.
• B. Gastric acidity.
• C. Gastric motility.
• D. Gastric pH.

Correct answer: D

Rationale: After a gastric vagotomy, the gastric pH increases as a result of reduced acid secretion.

5. 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.
