A client diagnosed with acute pancreatitis reports severe, knifelike pain radiating to the back. Which intervention should the nurse prioritize to manage this symptom?

Choice A rationale Acute pancreatitis involves inflammation and auto-digestion of the pancreas by its own enzymes, causing intense visceral pain that is often described as knifelike and radiating to the back. This severe pain is a major physiological stressor and requires aggressive, immediate pain management, making the administration of prescribed opioid analgesics the top priority to ensure client comfort and reduce the body's stress response. Choice B rationale While heat can provide comfort for muscle aches, it is generally avoided over the abdomen in cases of acute inflammation, such as pancreatitis, as it can potentially increase blood flow to the inflamed area. Furthermore, the pain from acute pancreatitis is visceral and deep, and topical heat application is unlikely to provide adequate relief for the severe, systemic, enzyme-mediated inflammatory process. Choice C rationale Eating, even small, frequent meals, stimulates the secretion of pancreatic enzymes via the hormone cholecystokinin, which is the primary pathophysiological driver of pancreatitis pain. Therefore, a client with acute pancreatitis should typically be kept NPO (nothing by mouth) to rest the pancreas and alleviate the pain, making this intervention inappropriate for pain management. Choice D rationale A comprehensive abdominal examination is an important part of the nursing assessment to monitor for complications such as peritonitis, but the client's report of severe, knifelike, radiating pain is a classic, established symptom of acute pancreatitis. While assessment should be ongoing, pain relief is the immediate, ethical, and clinical priority for this level of severe, debilitating pain, which must be addressed before or concurrent with a detailed physical assessment.
