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. A client is to take one daily dose of ranitidine (Zantac) at home to treat her peptic ulcer. The nurse knows that the client understands proper drug administration of ranitidine when she says that she will take the drug at which of the following times?

• A. Before meals
• B. With meals
• C. At bedtime
• D. When pain occurs

Correct answer: C

Rationale: Ranitidine (Zantac) is best taken at bedtime to reduce stomach acid production overnight.

3. A nurse is assigned to a 40-year-old client who has a diagnosis of chronic pancreatitis. The nurse reviews the laboratory result, anticipating a laboratory report that indicates a serum amylase level of

• A. 45 units/L
• B. 100 units/L
• C. 300 units/L
• D. 500 units/L

Correct answer: C

Rationale: The normal serum amylase level is 25 to 151 IU/L. With chronic cases of pancreatitis, the rise in serum amylase levels usually does not exceed three times the normal value. In acute pancreatitis, the value may exceed five times the normal value. Options 1 and 2 are within normal limits. Option 3 is an extremely elevated level seen in acute pancreatitis.

4. The nurse assesses the client's understanding of the relationship between body position and gastroesophageal reflux. Which response would indicate that the client understands measures to avoid problems with reflux while sleeping?

• A. I can elevate the foot of the bed 4 to 6 inches.
• B. I can sleep on my stomach with my head turned to the left.
• C. I can sleep on my back without a pillow under my head.
• D. I can elevate the head of the bed 4 to 6 inches.

Correct answer: D

Rationale: Sleeping with the head of the bed elevated encourages movement of food through the esophagus by gravity. By fostering esophageal acid clearance, gravity helps keep the acidic pepsin and alkaline biliary secretions from contacting the esophagus. Elevating the foot of the bed does not affect clearance of esophageal acid. Sleeping on the stomach with the head turned to the left will not decrease reflux incidence. Sleeping flat without a pillow under the head does not enhance clearance.

5. When assessing the client with celiac disease, the nurse can expect to find which of the following?

• A. Steatorrhea
• B. Jaundiced sclerae
• C. Clay-colored stools
• D. Widened pulse pressure

Correct answer: A

Rationale: Because celiac disease destroys the absorbing surface of the intestine, fat isn't absorbed but is passed in the stool. Steatorrhea is bulky, fatty stools that have a foul odor. Jaundiced sclerae result from elevated bilirubin levels. Clay-colored stools are seen with biliary disease when bile flow is blocked. Celiac disease doesn't cause a widened pulse pressure.
