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. Mucosal barrier fortifiers are used in peptic ulcer disease management for which of the following indications?

• A. To inhibit mucus production
• B. To neutralize acid production
• C. To stimulate mucus production
• D. To stimulate hydrogen ion diffusion back into the mucosa

Correct answer: C

Rationale: Mucosal barrier fortifiers stimulate mucus production, which helps protect the lining of the stomach and manage peptic ulcer disease.

3. The client has orders for a nasogastric (NG) tube insertion. During the procedure, instructions that will assist in the insertion would be:

• A. Instruct the client to tilt his head back for insertion in the nostril, then flex his neck for the final insertion
• B. After insertion into the nostril, instruct the client to extend his neck
• C. Introduce the tube with the client’s head tilted back, then instruct him to keep his head upright for final insertion
• D. Instruct the client to hold his chin down, then back for insertion of the tube

Correct answer: A

Rationale: Instructing the client to tilt his head back for insertion in the nostril, then flex his neck for the final insertion helps facilitate the NG tube insertion.

4. You’re patient is complaining of abdominal pain during assessment. What is your priority?

• A. Auscultate to determine changes in bowel sounds.
• B. Observe the contour of the abdomen.
• C. Palpate the abdomen for a mass.
• D. Percuss the abdomen to determine if fluid is present.

Correct answer: A

Rationale: When a patient is complaining of abdominal pain, the priority is to auscultate to determine changes in bowel sounds.

5. Which of the following mechanisms can facilitate the development of diverticulosis into diverticulitis?

• A. Treating constipation with chronic laxative use, leading to dependence on laxatives
• B. Chronic constipation causing an obstruction, reducing forward flow of intestinal contents
• C. Herniation of the intestinal mucosa, rupturing the wall of the intestine
• D. Undigested food blocking the diverticulum, predisposing the area to bacterial invasion

Correct answer: D

Rationale: The correct answer is D. Undigested food blocking the diverticulum can lead to bacterial invasion, causing inflammation and turning diverticulosis into diverticulitis. Choices A, B, and C do not directly facilitate the development of diverticulitis. Choice A involves a different mechanism related to laxative use, choice B describes a complication of chronic constipation but does not necessarily lead to diverticulitis, and choice C refers to a different condition involving herniation of the intestinal mucosa.
