Final answer:
The nurse would anticipate preparing the patient for endoscopy.
Step-by-step explanation:
In this case, the nurse would anticipate preparing the patient for endoscopy (option a). Endoscopy is a procedure in which a tube with a tiny camera is inserted into the patient's upper gastrointestinal (GI) tract to examine the area for any abnormalities or sources of bleeding. It allows for direct visualization of the stomach lining, esophagus, and duodenum, which can help determine the cause of coffee-ground emesis, such as peptic ulcers.
