A nurse is caring for a client with acute pancreatitis. Which of the following laboratory findings should the nurse expect?

Choice A reason: Elevated amylase and lipase are hallmark findings in acute pancreatitis. Pancreatic inflammation causes enzyme leakage into the bloodstream, with amylase and lipase levels rising within hours of onset. These enzymes digest carbohydrates and fats, respectively, and their elevation confirms pancreatic injury, aiding diagnosis alongside clinical symptoms like abdominal pain. Choice B reason: Decreased bilirubin is not typical in acute pancreatitis. Bilirubin may rise if pancreatitis causes biliary obstruction, but this is not a primary finding. The condition primarily affects pancreatic enzymes, not liver function markers like bilirubin, unless complications like gallstone pancreatitis or bile duct compression occur, which are secondary issues. Choice C reason: Elevated hemoglobin is not expected in acute pancreatitis. Hemoglobin may decrease due to inflammation, bleeding, or fluid shifts causing hemodilution. Pancreatitis does not stimulate erythropoiesis or concentrate blood, so elevated hemoglobin is more likely in dehydration or other conditions, not a primary feature of pancreatic inflammation. Choice D reason: Decreased calcium is common in acute pancreatitis due to fat necrosis and saponification, where calcium binds to fatty acids released from damaged pancreatic tissue. This reduces serum calcium levels, potentially causing hypocalcemia. Monitoring is critical, as low calcium can lead to neuromuscular irritability or cardiac complications in severe cases.
