Nursing Elites

1. Risk factors for the development of hiatal hernias are those that lead to increased abdominal pressure. Which of the following complications DOES NOT cause increased abdominal pressure?

• A. Obesity
• B. Volvulus
• C. Constipation
• D. Intestinal obstruction

Correct answer: B

Rationale: Obesity, constipation, and intestinal obstruction can all lead to increased abdominal pressure, which in turn can cause a hiatal hernia.

2. Jason, a 22 y.o. accident victim, requires an NG tube for feeding. What should you immediately do after inserting an NG tube for liquid enteral feedings?

• A. Aspirate for gastric secretions with a syringe.
• B. Begin feeding slowly to prevent cramping.
• C. Get an X-ray of the tip of the tube within 24 hours.
• D. Clamp off the tube until the feedings begin.

Correct answer: A

Rationale: Immediately after inserting an NG tube for enteral feedings, aspirate for gastric secretions to confirm proper placement.

3. A client with liver dysfunction has low serum levels of thrombin. The nurse provides care, anticipating that this client is most at risk of

• A. Dehydration
• B. Malnutrition
• C. Bleeding
• D. Infection

Correct answer: C

Rationale: Thrombin is produced by the liver and is necessary for normal clotting. When a client with liver dysfunction has low serum levels of thrombin, they are at risk of bleeding due to impaired clotting mechanisms. Dehydration (choice A) is not directly related to low thrombin levels. Malnutrition (choice B) may impact overall health but is not the most immediate concern associated with low thrombin levels. Infection (choice D) is not directly related to the clotting function affected by low thrombin levels.

4. A client has just had surgery for colon cancer. Which of the following disorders might the client develop?

• A. Peritonitis
• B. Diverticulosis
• C. Partial bowel obstruction
• D. Complete bowel obstruction

Correct answer: C

Rationale: After surgery for colon cancer, the client may develop a partial bowel obstruction.

5. 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.
