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. The client is admitted to the hospital with viral hepatitis, complaining of 'no appetite' and 'losing my taste for food.' To provide adequate nutrition, the nurse would instruct the client to

• A. Eat a good supper when anorexia is not as severe.
• B. Eat less often, preferably only three large meals daily.
• C. Increase intake of fluids including juices.
• D. Select foods high in fat.

Correct answer: C

Rationale: Although no special diet is required to treat viral hepatitis, it is generally recommended that clients consume a diet with low-fat content because fat may be tolerated poorly due to decreased bile production. Small, frequent meals are preferable and may prevent nausea. Appetite is often better in the morning, so it is easier to eat a good breakfast. An adequate fluid intake of 2500 to 3000 mL per day that includes nutritional juices is also important.

3. Which of the following tests should be administered to a client suspected of having diverticulosis?

• A. Abdominal ultrasound
• B. Barium enema
• C. Barium swallow
• D. Gastroscopy

Correct answer: B

Rationale: A barium enema is a diagnostic test used to visualize the colon and can help diagnose diverticulosis.

4. Which of the following diagnostic tests may be performed to determine if a client has gastric cancer?

• A. Barium enema
• B. Colonoscopy
• C. Gastroscopy
• D. Serum chemistry levels

Correct answer: C

Rationale: A gastroscopy is performed to visualize the stomach lining and obtain biopsies to diagnose gastric cancer.

5. The client being seen in a physician’s office has just been scheduled for a barium swallow the next day. The nurse writes down which of the following instructions for the client to follow before the test?

• A. Fast for 8 hours before the test
• B. Eat a regular supper and breakfast
• C. Continue to take all oral medications as scheduled.
• D. Monitor own bowel movement pattern for constipation

Correct answer: A

Rationale: Fasting for 8 hours ensures that the stomach is empty, which is necessary for an accurate barium swallow test.
