Nursing Elites

1. A patient with Crohn’s disease is admitted after 4 days of diarrhea. Which of the following urine specific gravity values do you expect to find in this patient?

• A. 1.005
• B. 1.011
• C. 1.02
• D. 1.03

Correct answer: D

Rationale: A urine specific gravity of 1.030 indicates concentrated urine, which is expected in a patient with dehydration due to diarrhea from Crohn’s disease.

2. Which of the following symptoms indicates diverticulosis?

• A. No symptoms exist
• B. Change in bowel habits
• C. Anorexia with low-grade fever
• D. Episodic, dull, or steady midabdominal pain

Correct answer: A

Rationale: Diverticulosis often has no symptoms and is usually found incidentally during tests for other conditions.

3. When teaching a community group about measures to prevent colon cancer, which instruction should the nurse include?

• A. Limit fat intake to 20% to 25% of your total daily calories.
• B. Include 15 to 20 grams of fiber into your daily diet.
• C. Get an annual rectal examination after age 35.
• D. Undergo sigmoidoscopy annually after age 50.

Correct answer: A

Rationale: Limiting fat intake is a recommended measure to reduce the risk of colon cancer. Including fiber, undergoing annual rectal examinations, and sigmoidoscopy are also important, but limiting fat intake is directly related to reducing cancer risk.

4. 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.

5. If a gastric acid perforates, which of the following actions should not be included in the immediate management of the client?

• A. Blood replacement
• B. Antacid administration
• C. Nasogastric tube suction
• D. Fluid and electrolyte replacement

Correct answer: B

Rationale: Antacid administration should not be included in the immediate management of a gastric perforation.
