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. Provide oral hygiene: While oral hygiene is important for comfort, it is not the priority intervention for a client with acute pancreatitis. The focus should be on managing the condition itself. B. Auscultate the client's lungs: Although lung assessment is important, it is not the immediate priority. The main concern in acute pancreatitis is managing the pancreas' inflammation and preventing complications. C. Assist the client to a side-lying position: Positioning may help with comfort, but the priority intervention is related to managing the pancreatitis by preventing further irritation to the pancreas through food or fluids. D. Withhold oral fluids and food: The priority intervention is to withhold oral fluids and food to allow the pancreas to rest and prevent stimulation of pancreatic enzymes, which can worsen inflammation. This is a key part of the initial management of acute pancreatitis.
