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. 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. The client has had a new colostomy created 2 days earlier. The client is beginning to pass malodorous flatus from the stoma. The nurse interprets that

• A. This indicates inadequate preoperative bowel preparation.
• B. This is a normal, expected event.
• C. The client is experiencing early signs of ischemic bowel.
• D. The client should not have the nasogastric tube removed.

Correct answer: B

Rationale: As peristalsis returns following creation of a colostomy, the client begins to pass malodorous flatus. This indicates returning bowel function and is an expected event. Within 72 hours of surgery, the client should begin passing stool via the colostomy.

5. A client is scheduled for oral cholecystography. Which one of the following actions would the nurse plan to implement before the test?

• A. Have the client drink 1000 mL of water.
• B. Ask the client about possible allergies to iodine or shellfish.
• C. Administer an intravenous contrast agent the evening before the test.
• D. Administer tap-water enemas until clear.

Correct answer: B

Rationale: Iodine compounds used as radiographic contrast agents, such as iopanoic acid (Telepaque), should not be administered to the client with iodine and seafood allergies because anaphylaxis may occur.
