A nurse is caring for a client with acute pancreatitis who has been experiencing severe abdominal pain and nausea for the past 24 hours. The client's vital signs are: temperature 101.2°F (38.4°C), heart rate 110 bpm, blood pressure 95/60 mmHg, and respirations 24/min. Laboratory results show elevated lipase levels at 850 U/L (normal: 10-140 U/L) and white blood cell count of 14,000/mm³. Which nursing intervention should be the priority?
1Administer prescribed analgesics for pain management
2Encourage deep breathing exercises to prevent respiratory complications
3Monitor blood glucose levels every 4 hours
4Maintain NPO status and monitor fluid balance✓ 정답
해설
In acute pancreatitis, maintaining NPO status is crucial to rest the pancreas and prevent further stimulation of pancreatic enzyme secretion, while careful fluid balance monitoring prevents complications from third-spacing and potential shock. Acute pancreatitis is a serious inflammatory disease of the pancreas that requires immediate and comprehensive nursing care. Prioritizing strict NPO status and fluid balance monitoring is important for several key reasons. The pathophysiology of acute pancreatitis involves autodigestion of pancreatic tissue by activated pancreatic enzymes, leading to inflammation, edema, and potential necrosis. Ingesting food or fluids stimulates the pancreas to produce digestive enzymes, which can worsen the inflammatory process and increase pain. By maintaining NPO status, the pancreas is allowed to rest, reducing enzyme production and limiting further tissue damage. Fluid balance monitoring is equally important because acute pancreatitis causes significant fluid shifts. The inflammatory process increases capillary permeability, causing fluid to leak into the abdominal cavity (third-spacing). This can lead to decreased blood volume, hypotension, and potentially hypovolemic shock. The patient's blood pressure of 95/60 mmHg and elevated heart rate of 110 bpm suggest early signs of fluid volume deficit. The elevated lipase level of 850 U/L confirms pancreatic inflammation, while the elevated white blood cell count indicates a systemic inflammatory response. The combination of fever, tachycardia, and borderline hypotension demands immediate attention to fluid status to prevent cardiovascular collapse. Pain management (option 1) is important but secondary to preventing life-threatening fluid imbalances and pancreatic stimulation. Respiratory care (option 2) helps prevent complications but is not the priority in the acute phase. Blood glucose monitoring (option 3) is a consideration in pancreatitis but does not address the immediate life threats. Adequate fluid resuscitation and pancreatic rest form the foundation of acute pancreatitis management and should be prioritized to prevent serious complications such as pancreatic necrosis, pseudocyst formation, or multi-organ failure.
Understanding the Priority: Fluid Resuscitation in Acute Pancreatitis
The client's presentation—fever, tachycardia, hypotension, and tachypnea—in the setting of a significantly elevated lipase and leukocytosis indicates a systemic inflammatory response. In acute pancreatitis (AP), activated pancreatic enzymes and inflammatory mediators cause massive vasodilation and increased capillary permeability, leading to a profound shift of fluid from the intravascular space into the interstitial "third space." This intravascular volume depletion is the primary driver of hypotension and tachycardia and, if uncorrected, can rapidly progress to hypovolemic shock and organ failure. The initial 24 to 72 hours are critical, as the management decisions made during this period directly influence clinical outcomes, including the development of pancreatic necrosis and organ failure [2].
Therefore, the priority nursing intervention is to maintain NPO (nil per os) status and meticulously monitor fluid balance. Placing the client NPO provides pancreatic rest by eliminating the cephalic and gastric phases of pancreatic enzyme secretion, which is a cornerstone of initial management. However, the more time-sensitive component of this intervention is the assessment of fluid balance to guide aggressive intravenous fluid resuscitation. Current guidelines emphasize that early, goal-directed fluid therapy is the single most important non-supportive intervention in the first phase of AP [2,3]. The nurse's role is to monitor intake and output strictly, assess for signs of fluid overload or continued deficit (e.g., vital sign trends, skin turgor, mucous membranes, urine output), and titrate IV fluids as prescribed, typically with Lactated Ringer's solution, to restore intravascular volume and maintain organ perfusion [2].
Analysis of Other Options
While the other interventions are important components of comprehensive care, they do not address the most immediate, life-threatening physiological derangement.
- Administer prescribed analgesics (Option 1): Pain management is a critical and early intervention in AP to reduce metabolic stress and splinting, which can impair breathing [2]. However, in this scenario, the client's vital signs point to a developing hypovolemic state. While pain medication should not be delayed unnecessarily, stabilizing the client's hemodynamic status through fluid resuscitation takes immediate precedence to prevent shock.
- Encourage deep breathing exercises (Option 2): Respiratory complications, such as pleural effusions and atelectasis, are common in AP due to the proximity of the inflammatory process to the diaphragm and pain-induced shallow breathing. Encouraging deep breathing is a valuable preventive measure, but it is not the priority over correcting the life-threatening hypovolemia indicated by the client's blood pressure of 95/60 mmHg and heart rate of 110 bpm.
- Monitor blood glucose levels (Option 3): The inflammatory destruction of pancreatic tissue can transiently impair endocrine function, specifically insulin production from beta cells, leading to hyperglycemia. Monitoring blood glucose is a necessary ongoing assessment, but it is a secondary concern compared to the immediate need for hemodynamic stabilization through fluid resuscitation and pancreatic rest.
The clinical picture of a client in the early phase of acute pancreatitis with signs of systemic inflammatory response syndrome (SIRS) and hypovolemia makes the maintenance of NPO status and rigorous monitoring of fluid balance the definitive priority nursing action [1,2,3].

Early Fluid Resuscitation in Acute PancreatitisPrioritizing NPO and Fluid Balance Monitoring
In the first 24–72 hours of acute pancreatitis, aggressive intravenous fluid resuscitation is the most critical intervention to counteract third-spacing and prevent hypovolemic shock. Maintaining NPO status rests the pancreas, while meticulous fluid balance monitoring guides therapy.
Assess for signs of intravascular volume depletion such as hypotension (95/60 mmHg), tachycardia (110 bpm), and rising hematocrit. The goal is to maintain urine output at >0.5 mL/kg/hr and reduce BUN levels.
Caution
Use lactated Ringer’s solution as the preferred crystalloid over normal saline to reduce the risk of hyperchloremic metabolic acidosis. Monitor for fluid overload, especially in older adults or those with cardiac or renal history.
Third-spacing — The pathological shift of fluid from the intravascular space into the interstitial space, common in acute pancreatitis due to inflammation, leading to hypovolemia.
NPO (Nil Per Os) — Nothing by mouth; a critical intervention in acute pancreatitis to rest the pancreas by preventing the release of digestive enzymes stimulated by oral intake.
SIRS (Systemic Inflammatory Response Syndrome) — A widespread inflammatory response to a clinical insult, manifested by two or more of the following: fever, tachycardia, tachypnea, and leukocytosis.
Autodigestion — The process by which the pancreas's own digestive enzymes are prematurely activated within the organ, leading to destruction of pancreatic tissue.
Lipase — A pancreatic enzyme that breaks down fats; elevated serum levels are a specific and sensitive marker for diagnosing acute pancreatitis.
