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 treatments is used for rectal cancer but not for colon cancer?

• A. Chemotherapy
• B. Colonoscopy
• C. Radiation
• D. Surgical resection

Correct answer: C

Rationale: Radiation therapy is commonly used for rectal cancer to shrink the tumor before surgery, which is not typically done for colon cancer.

3. Sharon has cirrhosis of the liver and develops ascites. What intervention is necessary to decrease the excessive accumulation of serous fluid in her peritoneal cavity?

• A. Restrict fluids
• B. Encourage ambulation
• C. Increase sodium in the diet
• D. Give antacids as prescribed

Correct answer: A

Rationale: Restricting fluids is necessary to decrease the excessive accumulation of serous fluid in the peritoneal cavity for a patient with ascites due to cirrhosis.

4. 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.

5. 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.
