Nursing Elites

1. A client who has had gastrectomy is not producing sufficient intrinsic factor. The nurse interprets that the client has lost the ability to absorb cyanocobalamin (vitamin B12) in the

• A. Stomach.
• B. Small intestine.
• C. Large intestine.
• D. Colon.

Correct answer: B

Rationale: Intrinsic factor is produced in the stomach but is used to aid in the absorption of vitamin B12 in the small intestine. Vitamin B12 is not absorbed in the large intestine (options 3 and 4).

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. Which goal of the client’s care should take priority during the first days of hospitalization for an exacerbation of ulcerative colitis?

• A. Promoting self-care and independence
• B. Managing diarrhea
• C. Maintaining adequate nutrition
• D. Promoting rest and comfort

Correct answer: B

Rationale: Managing diarrhea should take priority during the first days of hospitalization for an exacerbation of ulcerative colitis.

4. Radiation therapy is used to treat colon cancer before surgery for which of the following reasons?

• A. Reducing the size of the tumor
• B. Eliminating the malignant cells
• C. Curing the cancer
• D. Helping the bowel heal after surgery

Correct answer: A

Rationale: Radiation therapy is used before surgery to reduce the size of the tumor, making it easier to remove.

5. Which of the following definitions best describes diverticulosis?

• A. An inflamed outpouching of the intestine
• B. A noninflamed outpouching of the intestine
• C. The partial impairment of the forward flow of intestinal contents
• D. An abnormal protrusion of an organ through the structure that usually holds it

Correct answer: B

Rationale: The correct answer is B: 'A noninflamed outpouching of the intestine.' Diverticulosis refers to the presence of small, bulging pouches (diverticula) that can form in the lining of the digestive system, especially the colon. These pouches are typically noninflamed. Choice A is incorrect because it describes diverticulitis, which is the inflammation of these pouches. Choice C is incorrect as it defines bowel obstruction, not diverticulosis. Choice D is incorrect as it refers to a hernia, not diverticulosis.
