Nursing Elites

1. 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.

2. A client with a peptic ulcer is scheduled for a vagotomy. The client asks the nurse about the purpose of this procedure. The nurse tells the client that the procedure:

• A. Decreases food absorption in the stomach
• B. Heals the gastric mucosa
• C. Halts stress reactions
• D. Reduces the stimulus to acid secretions

Correct answer: D

Rationale: A vagotomy reduces the stimulus to acid secretions by cutting the vagus nerve, which innervates the stomach.

3. A client with liver dysfunction is having difficulty with protein metabolism. The nurse anticipates that the results of which of the following serum laboratory studies will be elevated?

• A. Lactic acid
• B. Ammonia
• C. Albumin
• D. Lactase

Correct answer: B

Rationale: During deamination of proteins, the liver splits the amino group from the carbon-containing compound, which results in the formation of ammonia and a carbon residue. The liver then converts the toxic ammonia substance into urea, which can be excreted by the kidneys. Clients with liver dysfunction may have high serum ammonia levels as a result.

4. When counseling a client in ways to prevent cholecystitis, which of the following guidelines is most important?

• A. Eat a low-protein diet
• B. Eat a low-fat, low-cholesterol diet
• C. Limit exercise to 10 minutes/day
• D. Keep weight proportionate to height

Correct answer: B

Rationale: Eating a low-fat, low-cholesterol diet is most important for preventing cholecystitis.

5. Colon cancer is most closely associated with which of the following conditions?

• A. Appendicitis
• B. Hemorrhoids
• C. Hiatal hernia
• D. Ulcerative colitis

Correct answer: D

Rationale: Ulcerative colitis is a condition closely associated with an increased risk of developing colon cancer due to chronic inflammation of the colon.
