The nurse is caring for a client who had a cholecystectomy two days ago. The client is febrile, reporting upper abdominal pain radiating to the back, and has had three episodes of vomiting in the last 8 hours. The nurse reviews the client's serum amylase and lipase level results which are twice the normal value. Based on these findings, the nurse should recognize the client is exhibiting symptoms of which condition?

Choice A reason: Hepatorenal failure involves progressive renal dysfunction due to severe liver disease. While fever and abdominal pain may occur in hepatic conditions, elevated amylase and lipase are not characteristic of hepatorenal syndrome. These enzymes specifically point to pancreatic involvement rather than liver-renal pathology. Choice B reason: Acute pancreatitis is the correct diagnosis because elevated serum amylase and lipase levels are hallmark indicators of pancreatic inflammation. The client’s symptoms—abdominal pain radiating to the back, vomiting, and fever—are classic for pancreatitis. Post-cholecystectomy, pancreatitis can occur due to retained gallstones or biliary complications, making this the most accurate recognition. Choice C reason: Surgical site infection could explain fever and abdominal pain, but it would not cause elevated amylase and lipase levels. These enzymes are specific to pancreatic injury, not wound infection. Thus, while infection is possible, it does not fit the laboratory findings. Choice D reason: Biliary duct obstruction can cause abdominal pain and vomiting, but the primary laboratory findings would include elevated bilirubin and alkaline phosphatase, not amylase and lipase. Obstruction may lead to pancreatitis, but the direct diagnosis here is acute pancreatitis.
