A nurse admits a client to the emergency department who reports nausea and vomiting that worsens when he lies down. Antacids do not help. The provider suspects acute pancreatitis. Which of the following laboratory test results should the nurse expect to see?

A. Increased serum calcium is not expected in acute pancreatitis; rather, clients often develop hypocalcemia due to fat necrosis binding calcium. B. Increased serum amylase is a classic finding in acute pancreatitis. Elevated amylase (and lipase) levels indicate pancreatic inflammation and enzyme leakage into the bloodstream. C. Decreased WBC is not typical; in fact, WBC is usually elevated due to the inflammatory process. D. Decreased serum lipase is incorrect; lipase levels are elevated along with amylase during acute pancreatitis.
