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 nursing measure would be most effective in helping the client cough and deep breathe after a cholecystectomy?

• A. Having the client take rapid, shallow breaths to decrease pain.
• B. Having the client lay on the left side while coughing and deep breathing.
• C. Teaching the client to use a folded blanket or pillow to splint the incision.
• D. Withholding pain medication so the client can be alert enough to follow the nurse's instructions.

Correct answer: C

Rationale: After a cholecystectomy, teaching the client to use a folded blanket or pillow to splint the incision will be most effective in helping the client cough and deep breathe. This technique provides support and reduces pain during coughing and deep breathing, promoting better lung expansion. Having the client take rapid, shallow breaths would not be effective in decreasing pain; instead, deep breathing is encouraged to prevent complications like atelectasis. Lying on the left side would limit lung expansion; therefore, the client should be positioned in semi-Fowler's or Fowler's position to maximize lung expansion. Withholding pain medication can lead to discomfort and reluctance to cough and deep breathe, hindering recovery.

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. Which of the following types of diets is implicated in the development of diverticulosis?

• A. Low-fiber diet
• B. High-fiber diet
• C. High-protein diet
• D. Low-carbohydrate diet

Correct answer: A

Rationale: A low-fiber diet is implicated in the development of diverticulosis because it leads to harder stools and increased pressure in the colon. The lack of fiber results in decreased bulk and slower transit time, predisposing individuals to constipation and the formation of diverticula. High-fiber diets, on the other hand, promote regular bowel movements and help prevent diverticular disease. High-protein and low-carbohydrate diets do not have a direct association with diverticulosis.

5. Elmer is scheduled for a proctoscopy and has an I.V. The doctor wrote an order for 5mg of I.V. diazepam(Valium). Which order is correct regarding diazepam?

• A. Give diazepam in the I.V. port closest to the vein.
• B. Mix diazepam with 50 ml of dextrose 5% in water and give over 15 minutes.
• C. Give diazepam rapidly I.V. to prevent the bloodstream from diluting the drug mixture.
• D. Question the order because I.V. administration of diazepam is contraindicated.

Correct answer: A

Rationale: The correct method for administering I.V. diazepam is to give it in the I.V. port closest to the vein.
