Gastrointestinal System ATI

Correct Answer: C

Rationale: Coffee-ground emesis is a sign of upper gastrointestinal bleeding that occurred approximately 2 hours earlier. It results from the breakdown of blood in the stomach due to digestive enzymes, giving it a coffee-ground appearance. Choice A is incorrect because coffee-ground emesis indicates older, partially digested blood, not fresh active bleeding. Choice B is incorrect as gastric lavage is not indicated for coffee-ground emesis. Choice D is incorrect because a transfusion of packed RBCs is not the immediate management for this presentation.

Correct Answer: C

Rationale: Coffee-ground emesis indicates that the gastric bleeding occurred 2 hours earlier.

Correct Answer: D

Rationale: After a gastric vagotomy, the gastric pH increases as a result of reduced acid secretion.

Correct Answer: A

Rationale: An ileostomy would have a malodorous, enzyme-rich, caustic liquid output that is yellow, green, or brown.

Correct Answer: C

Rationale: The correct answer is C: Provide frequent mouth care. In a patient with peritonitis who is NPO and thirsty, the priority is to maintain oral hygiene and provide comfort by moistening the mouth with frequent mouth care. This helps alleviate the sensation of thirst and maintains oral health. Increasing the IV infusion rate (choice A) may not address the patient's discomfort directly related to thirst. Using diversion activities (choice B) is not as critical as addressing the patient's immediate need for oral care. Giving ice chips every 15 minutes (choice D) is not recommended for a patient with peritonitis who is NPO, as it can lead to complications or worsen the condition.
