Final answer:
A nurse caring for a client with pancreatitis should expect the amylase level to be below the expected reference range.

Amylase is an enzyme produced in the pancreas, and its levels rise when there is inflammation or damage to the pancreas. Therefore, a decrease in amylase levels is typical in pancreatitis.
