Nursing Elites

1. A client has been diagnosed with gastroesophageal reflux disease. The nurse interprets that the client has dysfunction of which of the following parts of the digestive system?

• A. Chief cells of the stomach
• B. Parietal cells of the stomach
• C. Lower esophageal sphincter
• D. Upper esophageal sphincter

Correct answer: C

Rationale: The lower esophageal sphincter is a functional sphincter that normally remains closed except when food or fluids are swallowed. If relaxation of this sphincter occurs, the client could experience symptoms of gastroesophageal reflux disease.

2. The nurse is preparing to discontinue a client’s nasogastric tube. The client is positioned properly, and the tube has been flushed with 15 mL of air to clear secretions. Before removing the tube, the nurse makes which statement to the client?

• A. Take a deep breath when I tell you and breathe normally while I remove the tube.
• B. Take a deep breath when I tell you and bear down while I remove the tube.
• C. Take a deep breath when I tell you and slowly exhale while I remove the tube.
• D. Take a deep breath when I tell you and hold it while I remove the tube.

Correct answer: C

Rationale: The client should take a deep breath because the client’s airway will be obstructed temporarily during tube removal. The nurse then tells the client to exhale slowly and withdraws the tube during exhalation. Bearing down could inhibit the removal of the tube. Breathing normally could result in aspiration of gastric secretions during inhalation. Holding the breath does not facilitate tube removal.

3. If a client had irritable bowel syndrome, which of the following diagnostic tests would determine if the diagnosis is Crohn’s disease or ulcerative colitis?

• A. Abdominal computed tomography (CT) scan
• B. Abdominal x-ray
• C. Barium swallow
• D. Colonoscopy with biopsy

Correct answer: D

Rationale: A colonoscopy with biopsy is the most definitive diagnostic test to differentiate between Crohn's disease and ulcerative colitis.

4. A client with a peptic ulcer is scheduled for a vagotomy. The client asks the nurse about the purpose of this procedure. The nurse tells the client that the procedure:

• A. Decreases food absorption in the stomach
• B. Heals the gastric mucosa
• C. Halts stress reactions
• D. Reduces the stimulus to acid secretions

Correct answer: D

Rationale: A vagotomy reduces the stimulus to acid secretions by cutting the vagus nerve, which innervates the stomach.

5. Michael, a 42 y.o. man is admitted to the med-surg floor with a diagnosis of acute pancreatitis. His BP is 136/76, pulse 96, Resps 22 and temp 101. His past history includes hyperlipidemia and alcohol abuse. The doctor prescribes an NG tube. Before inserting the tube, you explain the purpose to patient.

• A. It empties the stomach of fluids and gas.
• B. It prevents spasms at the sphincter of Oddi.
• C. It prevents air from forming in the small intestine and large intestine.
• D. It removes bile from the gallbladder.

Correct answer: A

Rationale: Explain to the patient that the NG tube is used to empty the stomach of fluids and gas, which helps relieve symptoms of acute pancreatitis.
