Three days after a cholecystectomy for cholelithiasis, a client reports persistent upper abdominal pain that radiates to the back. The client has vomited three times in the last 12 hours and has a temperature of 101.8° F (38.7° C). Serum amylase and lipase are twice the normal value. Based on these findings, the nurse should observe the client for which pathophysiological condition?

The client's symptoms, along with the elevated serum amylase and lipase levels, suggest the development of acute pancreatitis as a postoperative complication. Here's a detailed explanation for why option A is the correct choice: A) Acute pancreatitis: Correct. Acute pancreatitis is characterized by inflammation of the pancreas, which can be triggered by various factors, including gallstones, alcohol consumption, and certain medications. In this case, the client's recent cholecystectomy for cholelithiasis (gallstones) may have led to the development of acute pancreatitis. The persistent upper abdominal pain radiating to the back, along with vomiting and fever, are classic symptoms of acute pancreatitis. Elevated serum amylase and lipase levels are common laboratory findings in acute pancreatitis due to pancreatic cell injury and leakage of these enzymes into the bloodstream. B) Surgical site infection: While surgical site infections are potential complications of cholecystectomy, the client's symptoms, including upper abdominal pain, vomiting, and fever, are more indicative of a systemic inflammatory process rather than localized infection at the surgical site. C) Hepatorenal failure: Hepatorenal failure, also known as hepatorenal syndrome, refers to kidney dysfunction that occurs as a complication of advanced liver disease. The client's symptoms and laboratory findings are not consistent with hepatorenal failure, as there are no signs of significant liver dysfunction or advanced liver disease. D) Biliary duct obstruction: While biliary duct obstruction can lead to symptoms similar to those of acute pancreatitis, such as upper abdominal pain and vomiting, the presence of elevated serum amylase and lipase levels strongly suggests pancreatic involvement rather than isolated biliary duct obstruction.
