A nurse is collecting data on a client who has acute pancreatitis. Which of the following factors should the nurse anticipate in the client's history?

A. Diabetes mellitus: Diabetes can be a consequence or comorbidity but is not a common antecedent risk factor that precipitates acute pancreatitis. B. Shock: Shock is a possible complication of severe pancreatitis (from third-spacing, hemorrhage, sepsis), not a historical risk factor the nurse would anticipate in the client's prior history. C. GERD: GERD is unrelated to the typical causes of acute pancreatitis. D. Gallstones: Gallstones are a common cause of acute pancreatitis (gallstone obstruction of the bile/pancreatic ducts can precipitate pancreatic inflammation), so gallstones are commonly found in the history.
