What diagnostic test should the nurse anticipate for an older patient who is vomiting "coffee-ground" emesis?
Endoscopy
Barium studies
Angiography
Gastric analysis
The Correct Answer is A
"Coffee-ground" emesis is a term used to describe vomit that has the appearance of coffee grounds, which indicates that the vomit contains partially digested blood. This is a serious symptom that could be indicative of an upper gastrointestinal bleed. An endoscopy is a diagnostic test that allows healthcare providers to visually examine the upper gastrointestinal tract and identify the source of bleeding.
Barium studies and angiography are not typically used to diagnose upper gastrointestinal bleeds. Gastric analysis may be useful in other diagnostic situations, but it is not the most appropriate test for a patient with "coffee-ground" emesis.

The nurse should take appropriate infection control measures, such as frequent handwashing, wearing gloves, and isolation precautions if necessary.
