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. 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.

3. The nurse is caring for a client following a Billroth II procedure. On review of the postoperative orders, which of the following if prescribed, should the nurse question and verify?

• A. Irrigating the nasogastric tube
• B. Coughing and deep breathing exercises
• C. Leg exercises
• D. Early ambulation

Correct answer: A

Rationale: In a Billroth II procedure the proximal remnant of the stomach is anastomosed to the proximal jejunum. Patency of the nasogastric tube is critical for preventing the retention of gastric secretions. The nurse should never irrigate or reposition the gastric tube after gastric surgery, unless specifically ordered by the physician. In this situation the nurse should clarify the order. Coughing and deep breathing exercises, leg exercises, and early ambulation are appropriate postoperative interventions.

4. A client with a history of gastric ulcer suddenly complains of a sharp-severe pain in the mid epigastric area, which then spreads over the entire abdomen. The client’s abdomen is rigid and board-like to palpation, and the client obtains most comfort from lying in the knee-chest position. The nurse calls the physician immediately suspecting that the client is experiencing which of the following complications of peptic ulcer disease?

• A. Perforation
• B. Obstruction
• C. Hemorrhage
• D. Intractability

Correct answer: A

Rationale: The signs and symptoms described in the question are consistent with perforation of the ulcer, which then progresses to peritonitis if the perforation is large enough. The client with intestinal obstruction most likely would complain of abdominal pain, distension, and nausea and vomiting. The client with hemorrhage would be vomiting blood or coffee-ground-like material or would be expelling black, tarry, or bloody stools. Intractability is a term that refers to continued symptoms of a disease process, despite ongoing medical treatment.

5. The nurse is reviewing the record of a client with Crohn’s disease. Which of the following stool characteristics would the nurse expect to note documented on the client’s record?

• A. Chronic constipation
• B. Diarrhea
• C. Constipation alternating with diarrhea
• D. Stool constantly oozing from the rectum

Correct answer: B

Rationale: Diarrhea is a common stool characteristic in clients with Crohn’s disease due to inflammation of the gastrointestinal tract.
