Acute PancreatitisNCLEX cheat sheet

Acute pancreatitis is sudden inflammation of the pancreas caused by premature activation of its own digestive enzymes, leading to autodigestion of the gland.

Causes

  • Gallstones + alcohol = top 2
  • Autodigestion of pancreas

Signs

  • Severe epigastric pain → back
  • N/V, fever, ↓ BS, ↑ HR
  • Cullen + Turner sign = severe

Labs

  • ↑ lipase (specific), ↑ amylase
  • ↓ Ca, ↑ glucose, ↑ WBC

Do

  • NPO, rest pancreas, IV fluids
  • Pain control, NG suction if vomiting
  • No alcohol; low-fat when resume
Key takeaway

Severe, boring epigastric pain radiating to the back is the hallmark, often worse after eating or lying flat and relieved by leaning forward.

Test yourself first: 5 questions

Question 1 of 5

A client is admitted with acute pancreatitis. Which finding does the nurse expect when reviewing the laboratory results?

What is acute pancreatitis?

The two leading causes are gallstones and chronic alcohol use. It causes severe epigastric pain that radiates to the back, and can progress to shock, respiratory failure, and multi-organ involvement. Elevated lipase and amylase confirm the diagnosis.

Key points to remember

  • Severe, boring epigastric pain radiating to the back is the hallmark, often worse after eating or lying flat and relieved by leaning forward.
  • Lipase is more specific and stays elevated longer than amylase; both rise sharply.
  • Nausea, vomiting, abdominal distention, and fever are common.
  • Cullen sign (periumbilical bruising) and Grey Turner sign (flank bruising) indicate hemorrhagic pancreatitis.
  • Hypocalcemia can occur as calcium binds to fatty acids (saponification), causing tetany.
  • Hyperglycemia may develop when insulin-producing islet cells are damaged.

Common causes

  • Gallstones + alcohol = top 2
  • Autodigestion of pancreas

Signs & symptoms

  • Severe epigastric pain → back
  • N/V, fever, ↓ BS, ↑ HR
  • Cullen + Turner sign = severe

Nursing priorities

  1. Keep the patient NPO to rest the pancreas and reduce enzyme stimulation.
  2. Administer IV fluids aggressively to prevent hypovolemia and maintain perfusion.
  3. Provide pain control with prescribed opioids and position the patient sitting up leaning forward (fetal/knee-chest comfort position).
  4. Monitor for hypocalcemia (Chvostek and Trousseau signs) and respiratory complications.
  5. Insert NG tube for decompression if vomiting or ileus is present, as ordered.

Labs & values

Lipase:0-160 U/L (markedly elevated, most specific)
Amylase:30-110 U/L (elevated)
Calcium:9-10.5 mg/dL (may be decreased); glucose may be elevated
0160U/L Normal

Patient teaching

  • Abstain from alcohol completely, as it is a major trigger and worsens the disease.
  • Follow a low-fat diet and eat small frequent meals when resuming oral intake.
  • Report recurring severe abdominal pain, fever, or vomiting to the provider.

Red flags: report now

  • Signs of shock (hypotension, tachycardia) or respiratory distress may indicate severe/hemorrhagic pancreatitis.
  • Cullen or Grey Turner sign signals internal hemorrhage and must be reported immediately.
  • Tetany, positive Chvostek/Trousseau, or seizures indicate dangerous hypocalcemia.
