1. The student nurse is participating in colorectal cancer-screening program. Which patient has the fewest risk factors for colon cancer?

Correct answer: C

Rationale: Herman, a 60 y.o. who follows a low-fat, high-fiber diet, has the fewest risk factors for colon cancer.

2. George has a T tube in place after gallbladder surgery. Before discharge, what information or instructions should be given regarding the T tube drainage?

Correct answer: B

Rationale: Before discharge, inform the patient that the drainage will decrease daily until the bile duct heals.

3. Which of the following techniques would the nurse use first to determine if a nasogastric tube is positioned in the stomach?

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.

Correct answer: B

Rationale: In the early stages of peritonitis, the client would exhibit abdominal pain and rigidity due to inflammation.

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