Rationale: Esophagogastroduodenoscopy (EGD) is a diagnostic test that involves visualizing the esophagus, stomach, and duodenum to diagnose ulcers.

Correct Answer: D

Rationale: If nausea occurs and persists, the client will need to be assessed for fluid and electrolyte imbalance. Explaining to the client that the majority of calories should be eaten in the morning hours is important because nausea occurs most often in the afternoon and evening. Clients should select a diet high in calories because energy is required for healing. Protein increases the workload on the liver. Changes in bilirubin interfere with fat absorption, so low-fat diets are tolerated better.

Correct Answer: A

Rationale: A barium swallow is an x-ray study that uses a substance called barium for contrast to highlight abnormalities in the gastrointestinal tract. The client should fast for 8 to 12 hours before the test, depending on physician instructions. Most oral medications also are withheld before the test. After the procedure the nurse must monitor for constipation, which can occur as a result of the presence of barium in the gastrointestinal tract.

Correct Answer: C

Rationale: For an oral cholecystogram, the client should eat a fat-free meal the evening before the procedure and avoid oral intake except for water on the day of the procedure. During the test, the client may be given a high-fat meal or drink to stimulate gallbladder emptying. Choice A is incorrect because the client should have a fat-free meal, not a high-fat meal. Choice B is incorrect as strict NPO status is not required. Choice D is incorrect as a high-fat meal is not recommended for breakfast on the day of the procedure.

Correct Answer: C

Rationale: Inserting a nasogastric tube is a priority intervention for a client with peptic ulcer disease to decompress the stomach.
