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.

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.

Correct Answer: C

Rationale: A Sengstaken-Blakemore tube is inserted into a client with a diagnosis of cirrhosis and ruptured esophageal varices. The tube has an esophageal and a gastric balloon. The esophageal balloon exerts pressure on the bleeding. The pressure of the esophageal balloon is released at intervals to decrease the risk of trauma to esophageal tissues, including esophageal rupture or necrosis. When the balloon is deflated the client may begin to bleed again from the esophageal varices, noted by vomiting of blood.

Correct Answer: A

Rationale: Following this procedure, the nurse monitors the client's vital signs closely for indications of hemorrhage and observes the needle insertion site for bleeding and bile leakage. A sandbag is placed over the insertion site to prevent bleeding. The client is maintained on bedrest, and oral intake is avoided in the immediate postprocedure period in case surgery is necessary to control hemorrhage of bile extravasation.

Correct Answer: B

Rationale: The pain that is associated with acute pancreatitis is often severe and is located in the epigastric region and radiates to the back. Options 1, 3, and 4 are incorrect because they are not specific for the pain experienced by the client with pancreatitis.
