Clinical meaning
Acute pancreatitis is inflammation of the pancreas—often related to gallstones or alcohol, sometimes hypertriglyceridemia, ERCP, or trauma. It ranges from mild (pain + nausea) to necrotizing disease with SIRS, organ failure, and hypovolemic shock themes. NCLEX-RN rewards linking epigastric pain radiating to the back, nausea/vomiting, fever, and tenderness with priority nursing actions: NPO, IV access, aggressive monitoring, labs per orders, and early escalation for hypotension or altered mentation. You are not expected to interpret CT independently, but you must recognize hemodynamic collapse and hypocalcemia risk patterns when the stem provides data. Pair with fluid balance, DKA vs HHS, and shock recognition
