Nursing Elites

1. 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.

2. To prevent gastroesophageal reflux in a client with hiatal hernia, the nurse should provide which discharge instructions?

• A. Lie down after meals to promote digestion.
• B. Avoid coffee and alcoholic beverages.
• C. Take antacids before meals.
• D. Limit fluids with meals.

Correct answer: B

Rationale: To prevent reflux of stomach acid into the esophagus, the nurse should advise the client to avoid foods and beverages that tend to increase stomach acid, such as coffee and alcohol. The nurse also should teach the client to avoid lying down after meals, which can aggravate reflux, and to take antacids after eating. The client doesn't need to limit fluids with meals as long as the fluids aren't gastric irritants.

3. Lactulose (Chronulac) is prescribed for a client with a diagnosis of hepatic encephalopathy. The nurse would determine that this medication has had a therapeutic effect if which of the following is noted?

• A. Increased red blood cell count
• B. Decreased serum ammonia level
• C. Increased protein level
• D. Decreased white blood cell level

Correct answer: B

Rationale: Lactulose is prescribed for the client with hepatic encephalopathy to reduce bacterial breakdown of protein in the bowel. The medication creates an acidic environment in the bowel and causes the ammonia to leave the bloodstream and enter the colon. Ammonia then becomes trapped in the bowel. Lactulose also has a laxative effect that allows for the elimination of the ammonia.

4. Which of the following nursing interventions should have the highest priority during the first hour after the admission of a client with cholecystitis who is experiencing pain, nausea, and vomiting?

• A. Administering pain medication.
• B. Completing the admission history.
• C. Maintaining hydration.
• D. Teaching about planned diagnostic tests.

Correct answer: A

Rationale: Administering pain medication would have the highest priority during the first hour after the client's admission. Pain relief is essential to address the client's immediate discomfort and distress. Completing the admission history, maintaining hydration, and teaching about planned diagnostic tests are important aspects of care but can be addressed after addressing the client's pain and stabilizing their condition.

5. The client being treated for esophageal varices has a Sengstaken-Blakemore tube inserted to control the bleeding. The most important assessment is for the nurse to:

• A. Check that the hemostat is on the bedside
• B. Monitor IV fluids for the shift
• C. Regularly assess respiratory status
• D. Check that the balloon is deflated on a regular basis

Correct answer: C

Rationale: Regularly assessing respiratory status is crucial when a Sengstaken-Blakemore tube is inserted to control bleeding in esophageal varices.
