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 is providing instructions to a client who is scheduled for an oral cholecystogram. The nurse tells the client to

• A. Eat a fat-free meal on the evening before the procedure.
• B. Maintain strict NPO status on the day of the procedure.
• C. Avoid oral intake except for water on the day of the procedure.
• D. Eat a high-fat meal for breakfast on the day of the procedure.

Correct answer: C

Rationale: For an oral cholecystogram, the client should eat a fat-free meal the evening before the procedure and avoid oral intake except for water on the day of the procedure. During the test, the client may be given a high-fat meal or drink to stimulate gallbladder emptying. Choice A is incorrect because the client should have a fat-free meal, not a high-fat meal. Choice B is incorrect as strict NPO status is not required. Choice D is incorrect as a high-fat meal is not recommended for breakfast on the day of the procedure.

3. You’re preparing a patient with a malignant tumor for colorectal surgery and subsequent colostomy. The patient tells you he’s anxious. What should your initial step be in working with this patient?

• A. Determine what the patient already knows about colostomies.
• B. Show the patient some pictures of colostomies.
• C. Arrange for someone who has a colostomy to visit the patient.
• D. Provide the patient with written material about colostomy care.

Correct answer: A

Rationale: When a patient with a malignant tumor is anxious about colorectal surgery and a colostomy, the initial step is to determine what the patient already knows about colostomies.

4. A client being treated for chronic cholecystitis should be given which of the following instructions?

• A. Increase rest
• B. Avoid antacids
• C. Increase protein in diet
• D. Use anticholinergics as prescribed

Correct answer: D

Rationale: Using anticholinergics as prescribed can help manage the symptoms of chronic cholecystitis.

5. Which of the following techniques would the nurse use first to determine if a nasogastric tube is positioned in the stomach?

• A. Aspirating with a syringe and observing for the return of gastric contents.
• B. Irrigating with normal saline and observing for the return of solution.
• C. Placing the tube's free end in water and observing for air bubbles.
• D. Instilling air and auscultating over the epigastric area for the presence of the tube.

Correct answer: A

Rationale: The initial way to determine if a nasogastric tube is in the stomach is to apply suction to the tube with a syringe and observe for the return of stomach contents. Then the pH of the aspirate can be measured. This is the method of choice. One would not irrigate until tube placement is confirmed. Observing for air bubbles when the free end of the tube is placed under water is an unacceptable, unsafe method of determining tube placement. Another method is to instill air into the tube with a syringe while auscultating over the epigastric area. Hearing the air enter the stomach helps ensure proper placement, but the method is not foolproof and is no longer considered an effective or preferred way to determine placement.
