ATI Gastrointestinal System

Correct Answer: C

Rationale: The discomfort of reflux is aggravated by positions that compress the abdomen and the stomach. Lying flat on the back (supine) or on the stomach (prone) after a meal can exacerbate symptoms. Similarly, lying on the right side can worsen reflux. The most appropriate position to alleviate discomfort in a client with gastroesophageal reflux disease is lying on the left side with the head of the bed elevated at a 30-degree angle. This position helps prevent the backflow of stomach contents into the esophagus, providing relief to the client.

Correct Answer: D

Rationale: It is best for the client to take the antacid 1 to 3 hours after meals to ensure effectiveness.

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: To accurately assess for jaundice in a patient with dark skin pigmentation, the nurse should examine the hard palate of the mouth. Jaundice is best assessed in the sclera; however, in dark-skinned patients, normal yellow pigmentation may be present in the sclera, making it difficult to detect jaundice. Inspection of the hard palate for a yellow color can confirm the presence of jaundice. Cyanosis is best observed in the nail beds, not indicative of jaundice. While skin on the palm of the hand can indicate jaundice, the back of the hand is not a typical area for assessment. Jaundice can be assessed on the soles of the feet in dark-skinned patients, but it is better visualized in the hard palate for accurate evaluation.

Correct Answer: D

Rationale: A vagotomy, or cutting of the vagus nerve, is done to eliminate parasympathetic stimulation of gastric secretion, thereby reducing the stimulus to acid secretions. Options A, B, and C are incorrect as a vagotomy does not affect food absorption, heal the gastric mucosa, or halt stress reactions.
