She has no retrosternal or epigastric pain. Physical exam is significant for dry mucous membranes and mild epigastric tenderness. Her recent hemoglobin A1C was elevated at 12.2. The symptoms of early satiety, nausea, vomiting, and postprandial fullness point towards a diagnosis of gastroparesis. Gastroparesis is a known complication of longstanding diabetes mellitus and is likely the cause of her symptoms. Of the answer choices provided, metoclopramide is a prokinetic agent that increases gastrointestinal motility by antagonizing dopamine receptors. It is commonly used to treat symptoms of diabetic gastroparesis. Omeprazole treats GERD and peptic ulcer disease but not gastroparesis. Clarithromycin is an antibiotic and not indicated. Ondansetron is an antiemetic but does not treat the underlying cause. Calcium carbonate is used as a phosphate binder and antacid but does not treat gastroparesis.C: Metoclopramide
