1. 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.
2. Which of the following tests is most commonly used to diagnose cholecystitis?
- A. Abdominal CT scan
- B. Abdominal ultrasound
- C. Barium swallow
- D. Endoscopy
Correct answer: B
Rationale: An abdominal ultrasound is the most commonly used test to diagnose cholecystitis.
3. 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.
4. The client with a new colostomy is concerned about the odor from stool from the ostomy drainage bag. The nurse teaches the client to include which of the following foods in the diet to reduce odor?

- B. Broccoli

- D. Eggs
Correct answer: A
Rationale: The client should be taught to include deodorizing foods in the diet, such as beet greens, parsley, buttermilk, and yogurt. Spinach also reduces odor but is a gas-forming food as well. Broccoli, cucumber, and eggs are gas-forming foods.
5. Which of the following factors is believed to be linked to Crohn’s disease?
