A nurse is caring for a client who has acute pancreatitis. After treating the client's pain, which of the following should the nurse address as the priority intervention?

A. In acute pancreatitis, the priority intervention after pain control is to withhold oral fluids and food to prevent stimulation of the pancreas, which can worsen inflammation and pain. This helps minimize pancreatic enzyme secretion. B. Auscultating the lungs is important for overall assessment but is not the priority at this stage. C. Oral hygiene is supportive care but is not urgent compared to preventing further pancreatic stimulation. D. Positioning for comfort is helpful but secondary to preventing GI stimulation, making NPO status the top priority.
