NGN Case Studies: How the Unfolding Chart Actually Works
An NGN unfolding case study gives you one client and six linked questions, with the medical record growing as the case progresses: new nurses' notes, vital signs and laboratory results appear between items. The six questions follow the clinical judgment model in order: recognize cues, analyze cues, prioritize hypotheses, generate solutions, take action, and evaluate outcomes.

An unfolding case study is six questions about one client, answered in order, with a medical record that grows as you go. It is the closest the NCLEX comes to a shift on a real unit — and the format itself carries information, if you know how to read it.
How one is built
You get a client and a chart with tabs — nurses' notes, vital signs, laboratory results, orders. Then six questions, each one mapped to a step of the clinical judgement model, in this fixed order:
| Item | Step | Typical format |
|---|---|---|
| 1 | Recognize cues | Highlight the findings that need follow-up |
| 2 | Analyze cues | Select all that apply, or a matrix |
| 3 | Prioritize hypotheses | Cloze — "the client is most likely experiencing ___ as evidenced by ___" |
| 4 | Generate solutions | Matrix — indicated or contraindicated |
| 5 | Take action | Multiple choice — what first? |
| 6 | Evaluate outcomes | Matrix — improved or not improved |
The chart grows, and that is a clue
New entries appear as you progress — a repeat set of vitals, a lab that has come back, a note from an hour later. When new information appears, it is there because it changes something. A case that hands you a hemoglobin at item 2 is telling you the next question depends on it.
Read the timestamps. Two sets of vital signs at 0800 and 0845 are not two facts, they are a trend, and the trend is usually the point.
You cannot go back
Each item locks when you move on. Two consequences worth planning for:
- Budget as a block, not per question. Twelve to fifteen minutes for the whole case. Item 1 legitimately takes longest because you are reading the chart for the first time; items 4 to 6 reuse that reading and go quickly.
- A wrong early answer does not sink the case. Items are scored independently, so misjudging the diagnosis at item 3 does not automatically cost you items 4 to 6 — but only if you keep reasoning from the chart rather than defending your earlier answer.
Working one through
Take a client one day after a total hip replacement. The 0800 note says: alert and oriented, reports increasing thirst, surgical dressing with a 4 cm area of bright red drainage, pain 4 out of 10, pedal pulses palpable.
| Step | The reasoning |
|---|---|
| Recognize cues | Sort expected from unexpected. Oriented, pain 4/10 and palpable pulses are all expected after this surgery. Increasing thirst and bright red drainage are not |
| Analyze cues | Labs arrive: hemoglobin 8.9 from a pre-op 13.1. That is not chronic anemia, that is loss — and it fits the thirst |
| Prioritize hypotheses | Visible bleeding plus falling hemoglobin plus compensatory thirst = hypovolemic shock from hemorrhage. Not sepsis — no fever, and infection needs time |
| Generate solutions | Fluids, oxygen and reinforcing the dressing are indicated. Removing the dressing is contraindicated — it strips the clot doing the work |
| Take action | Vitals now 122 and 88/54, urine 20 mL/hr. Compensation is failing. Notify the surgeon and prepare for theatre — fluids buy minutes, only surgery stops a surgical bleed |
| Evaluate outcomes | Heart rate 104 (was 122) and urine 35 mL/hr are improvements. Hemoglobin 8.7 (was 8.9) is not — crystalloid restores pressure but dilutes what is left |
That last row is the one students miss. Evaluation compares against this client's own earlier numbers, not textbook normals. A heart rate of 104 is still abnormal and still an improvement.
What separates a strong performance
| Habit | Why it pays |
|---|---|
| Open every chart tab before answering item 1 | The lab that explains the note is often in a tab you did not click |
| Say the diagnosis out loud to yourself by item 3 | Items 4 to 6 all hang off it; leaving it vague makes them guesses |
| Re-read the new entries at each step | They were added deliberately |
| Answer only what you believe | Partial credit deducts for wrong selections on many item types |
NCLEX tip: Case studies are worth practising as whole cases, not as loose questions. The skill being tested is carrying one clinical picture across six decisions — and you cannot rehearse that by answering six unrelated items.

Frequently asked questions
Common follow-up questions on The 2026 Test Plan & Next Gen NCLEX.
How many questions are in an NGN case study?
Six, always about the same client, and they must be answered in sequence. You cannot return to an earlier item once you have moved on, so each answer should be given on the information available at that point in the chart.
What are the six steps of the clinical judgment model?
Recognize cues, analyze cues, prioritize hypotheses, generate solutions, take action, and evaluate outcomes. Each step becomes one question in the case study, which is why identifying which step you are on tells you what kind of answer is wanted.
Do I need to re-read the whole chart for every question?
Read the new entries carefully: the chart unfolds, and the tab carrying fresh information usually holds the key to the current question. Time is better spent on what has changed since the last item than on re-reading unchanged history.
Are case study questions scored individually?
Yes. Each of the six items is scored on its own with partial credit, so an early mistake does not cascade through the rest of the case. Answering the later steps well still earns marks.
