NCLEX-RN® NGN Case Study: Adult with Epigastric Pain and Acute Pancreatitis

An NGN case study on a 44-year-old with deep epigastric pain, vomiting, and an elevated lipase — cues that flag third-spacing risk, how to rank the differentials, and the safe order of nursing actions.

A deep-belly pain that has been missed before

A 44-year-old comes to the emergency department after vomiting through the night. The client describes a deep, gnawing epigastric pain that bores straight through to the back, started about 12 hours ago after a heavy meal, and feels worse lying flat and a little better leaning forward. The client has a history of cholelithiasis ("they said the stones aren't bothering me yet") and reports two to three drinks most evenings.

Vitals show a temperature of 38.0°C, heart rate 116, blood pressure 108/64, respiratory rate 22, SpO₂ 96% on room air. The abdomen is tender across the upper quadrants with voluntary guarding, no rebound. Bowel sounds are diminished. Lipase comes back markedly elevated. The client says, "Please give me something for the pain — I just need to sleep."

That is the entire opening of this NGN case study. Nothing on screen says "acute pancreatitis with the risk of getting much worse". The case asks you to behave like the ED RN who recognises that the calm-looking belly can hide a third-spacing emergency by morning.

What this case is testing

The case is built around acute pancreatitis with early signs of severity because it forces a full pass through the NCSBN Clinical Judgment Measurement Model on a fluid-shifting abdominal emergency:

Recognize cues that change "bad gastroenteritis" to "acute pancreatitis with risk of progression" — the pain pattern, the vomiting, the lipase value, the borderline vitals, the risk-factor history.
Analyze cues the way a med-surg nurse would — knowing why third-spacing matters, how the early hematocrit or urine output hints at intravascular volume, and how this case can drift toward SIRS or organ failure within hours.
Prioritize hypotheses when more than one differential could explain the picture — pancreatitis, perforated ulcer, cholangitis, mesenteric ischaemia, atypical MI.
Generate solutions that match the early management plan — IV access, fluid resuscitation goals, NPO and bowel rest, analgesia choice, antiemetic, and monitoring intervals.
Take action in the right order — the case will test whether you know which intervention cannot wait and which step requires a provider order before the nurse proceeds.
Evaluate outcomes after the first interventions using new vitals, urine output, the pain score, and any new abdominal findings.

Underneath the case you will touch several Client Needs categories at once: Safe and Effective Care Environment, Physiological Adaptation, Pharmacology and Parenteral Therapies (crystalloids, opioids, antiemetics), Reduction of Risk Potential, Basic Care and Comfort for the positioning and oral-care reasoning, and Health Promotion and Maintenance for the alcohol and gallstone teaching that closes the case.

Who this case is good for

This is a senior-level NCLEX-RN® case study. It is a strong fit for:

Senior nursing students preparing for NCLEX-RN® who have completed a med-surg rotation.
Recent graduates working through NGN cases in the final stretch of a 30-, 60-, or 90-day NCLEX-RN® study plan.
Internationally educated nurses preparing for NCLEX-RN® who want practice with US fluid-resuscitation reasoning in non-trauma abdominal pain.
Anyone who can list the Ranson criteria but freezes when the bedside picture is "borderline" rather than dramatic.

It is not the right first NGN case for a student who has only done multiple-choice questions so far. If that's you, start with the in-app NGN tutorial the first time you open any case — it walks the six clinical-judgment steps in plain language.

What you will work through, step by step

Inside the case you will move through six linked sub-items. Each ties to a single step in the CJMM clinical-judgment cycle and unlocks the next.

The opening sub-item asks you to highlight the cues that change the story from "gastroenteritis" to "acute pancreatitis with risk of progression". Picking too many cues is as wrong as picking too few.
The analyse sub-item asks you to match cues to a probable physiological process — third-spacing, bile-duct obstruction, or something else.
A prioritisation sub-item asks you to rank the differentials by how dangerous they would be if missed, not by what feels most likely.
An action sub-item asks for the single first nursing action. Two of the choices look almost identical — separating them is the whole point of the item.
A handoff sub-item asks you to assemble an SBAR report to the admitting provider using building blocks instead of free text.
The closing sub-item asks you to evaluate the response after the first round of interventions using fresh vitals, urine output, a new pain score, and the client's own words.

At the end you will see your overall score, sub-item by sub-item feedback, and a short reflection prompt that feeds your Mistake DNA inside RN Clarity.

Why this case shows up in NCLEX-RN® prep so often

Acute pancreatitis is one of the most-tested presentations on the current NCLEX-RN® test plan because it rewards the reasoning the exam was designed to measure — multiple body systems, a fluid-shifting trajectory, and a single ordered series of nursing actions where doing the safest thing in the safest order changes the outcome.

If you can think your way through this case calmly, you will have practised the same clinical-reasoning loop NCLEX-RN® test writers reward, on a presentation you are likely to see during your first months as a nurse.

There is no spoiler here on purpose. An NGN case is about the reasoning you do while the screen is in front of you, not the answer key afterward. The case is open to free-preview members and full subscribers inside the RN Clarity NGN bank.
