question: Q:A 59-year-old woman comes to the clinic complaining of an intermittent, gnawing epigastric pain for the past 2 months. The pain is exacerbated with food and has been getting progressively worse. The patient denies any weight changes, nausea, vomiting, cough, or dyspepsia. Medical history is significant for chronic back pain for which she takes ibuprofen. Her father passed at the age of 55 due to pancreatic cancer. Labs were unremarkable except for a mild decrease in hemoglobin. To what medication is most appropriate to be switched from the current medication at this time?? 
  {'A': 'Acetaminophen', 'B': 'Aspirin', 'C': 'Naproxen', 'D': 'Omeprazole', 'E': 'Ranitidine'},
