Nursing Elites

1. 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.

2. The client being seen in a physician’s office has just been scheduled for a barium swallow the next day. The nurse writes down which of the following instructions for the client to follow before the test?

• A. Fast for 8 hours before the test
• B. Eat a regular supper and breakfast
• C. Continue to take all oral medications as scheduled.
• D. Monitor own bowel movement pattern for constipation

Correct answer: A

Rationale: Fasting for 8 hours ensures that the stomach is empty, which is necessary for an accurate barium swallow test.

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. A nurse is caring for a client diagnose with pancreatitis. The nurse anticipates that the client would not experience an elevation of which of the following enzymes?

• A. Lipase
• B. Lactase
• C. Amylase
• D. Trypsin

Correct answer: B

Rationale: Lactase is produced in the small intestine and aids in splitting neutral fats into glycerol and fatty acids. Lipase, amylase, and trypsin are produced in the pancreas and aid in the digestion of fats, starches, and proteins, respectively.

5. A client is suspected of having hepatitis. Which diagnostic test results will assist in confirming this diagnosis?

• A. Decreased erythrocyte sedimentation rate
• B. Elevated serum bilirubin
• C. Elevated hemoglobin
• D. Elevated blood urea nitrogen

Correct answer: B

Rationale: Laboratory indicators of hepatitis include elevated liver enzyme levels, elevated serum bilirubin levels, elevated erythrocyte sedimentation rates, and leucopenia. An elevated blood urea nitrogen may indicate renal dysfunction. A hemoglobin level is unrelated to this diagnosis.
