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?

A. Hepatorenal failure: Hepatorenal failure is characterized by impaired liver and kidney function, often indicated by rising creatinine, BUN, and liver function tests, along with oliguria and jaundice. While the client has abdominal pain and vomiting, the key laboratory findings are not consistent with hepatorenal failure and instead point to pancreatic involvement. B. Acute pancreatitis: Acute pancreatitis commonly presents with upper abdominal pain radiating to the back, nausea, vomiting, and systemic signs such as fever. Elevated serum amylase and lipase levels, typically two to three times the normal range, are hallmark diagnostic indicators. The timing after cholecystectomy suggests a biliary cause triggering pancreatic inflammation. Prompt recognition is essential to manage pain, hydration, and complications. C. Biliary duct obstruction: Biliary obstruction can cause right upper quadrant pain, jaundice, and sometimes nausea, but the hallmark laboratory finding is elevated bilirubin and alkaline phosphatase rather than elevated pancreatic enzymes. Although obstruction may contribute to pancreatitis, the client’s significant rise in amylase and lipase indicates pancreatic inflammation. D. Surgical site infection: Surgical site infections often present with localized erythema, warmth, purulent drainage, and sometimes fever. While the client is febrile, the pain is primarily upper abdominal and radiates to the back, and laboratory results indicate elevated pancreatic enzymes, which are not typical for a localized surgical wound infection.
