A nurse is reviewing the diagnostic tests for pancreatitis with a group of students. What test is considered a highly specific and sensitive indicator of pancreatic injury?

A) Incorrect. GERD primarily involves acid reflux and heartburn, not severe upper abdominal pain.

B) Incorrect. PUD is characterized by ulcers in the stomach or duodenum, which may cause pain, but it typically doesn't present with severe upper abdominal pain and nausea.

C) Correct. Pancreatitis is characterized by severe upper abdominal pain, nausea, and vomiting. It is often a result of inflammation of the pancreas.

D) Incorrect. Gastritis involves inflammation of the stomach lining and can cause abdominal discomfort, but it is not typically associated with severe upper abdominal pain.

A) Incorrect. Continuing with the regular diet, especially without modifications, may exacerbate symptoms in a client with acute pancreatitis.

B) Incorrect. While a clear liquid diet may be indicated initially, it is not the long-term dietary recommendation for someone with acute pancreatitis.

C) Incorrect. A high-fat, low-carbohydrate diet is not recommended for someone with pancreatitis, as it can exacerbate symptoms.

D) Correct. Starting with a low-fat, bland diet and gradually advancing as tolerated is a common dietary recommendation for clients with acute pancreatitis. This approach allows the pancreas to rest and recover.
