Free NCLEX case studies with full rationales
The Next Generation NCLEX (NGN) replaced isolated clinical questions with unfolding case studies that test how nurses actually think. Each case gives you a real patient scenario, then walks you through the six steps of the NCSBN Clinical Judgment Measurement Model: recognize cues, analyze cues, prioritize hypotheses, generate solutions, take actions, and evaluate outcomes. The cases below are five of the 5,000+ practice items in the Clarity bank — no signup required to try them.
What is an NCLEX case study, exactly?
Starting April 2023, the NCLEX-RN became the Next Generation NCLEX, and case studies became the centerpiece of the exam. A case study is a single patient scenario followed by six sequential questions that escalate from recognition to action to evaluation. Unlike a standalone multiple-choice item, the answers you choose early in the case can shape the data you see later — exactly like clinical practice.
The NCSBN built the format to address a documented gap: new graduate nurses score well on standalone questions but struggle with the layered judgment of real patient care. Case studies test that integration directly.
The six steps of the Clinical Judgment Measurement Model
- Recognize cues. Pick out the data in the chart that matter. Not all findings are clinically significant — the case study tests your ability to filter.
- Analyze cues. Connect findings to pathophysiology. A potassium of 3.0 plus furosemide plus muscle weakness paints a different picture than each finding alone.
- Prioritize hypotheses. Several diagnoses could fit. Rank them by likelihood and urgency, and decide which to investigate first.
- Generate solutions. Identify the nursing actions, provider orders, and patient teaching that address the top hypothesis.
- Take actions. Execute the most appropriate solution. Often this is a bow-tie question with one condition in the middle and actions plus monitoring on either side.
- Evaluate outcomes. Reassess. Did the intervention work? Is the patient improving, stable, or declining?
How to study NCLEX case studies effectively
The mistake most students make is treating case studies like long multiple-choice questions. They're not. Three habits separate students who pass on the first try:
- Read the scenario twice before the first question. The first read gives you the headline. The second read makes you notice the lab trends, the timeline, and the patient history that the test writers planted on purpose.
- Predict the next question. If the scenario shows a deteriorating postpartum client, predict whether the next question will ask about hemorrhage, eclampsia, or PE before the answer choices load. This trains your clinical reasoning, not just your test-taking.
- Write down the priority cue. One sentence: "The cue that changes the next safest action is ___." If you can name that cue, you'll answer correctly. If you can't, slow down and reread.
Topics covered in the 5 cases below
These five sample cases span the highest-yield categories the NCSBN test plan emphasizes: cardiac emergency, anaphylaxis, endocrine crisis, traumatic brain injury, and obstetric hemorrhage. Each is at the difficulty level you'll see on the live exam — not easier, not harder.

- Question 1 · Cardiac · NGN case study
A 62-year-old client arrives in the ED with crushing substernal chest pain radiating to the left arm, diaphoresis, and a heart rate of 112 bpm. The 12-lead ECG shows ST elevation in leads II, III, and aVF. Troponin is 4.8 ng/mL. The provider orders aspirin 325 mg, sublingual nitroglycerin, and prepares for cardiac catheterization. Which finding would most prompt the nurse to hold the nitroglycerin?
- a.Blood pressure 88/52 mmHg
- b.Heart rate 102 bpm
- c.Reports pain of 7/10
- d.SpO2 95% on 2L nasal cannula
Show answer + rationale
Correct: A. Inferior wall MI (II, III, aVF) frequently involves the right ventricle, which is preload-dependent. Nitroglycerin causes venodilation, dropping preload, and in RV infarction can precipitate profound hypotension and shock. A systolic of 88 with an inferior STEMI is an absolute contraindication. Heart rate 102 is appropriate sympathetic response, pain warrants treatment, and SpO2 95% is acceptable.
- Question 2 · Respiratory · NGN case study
A 4-year-old with a known peanut allergy is brought to the clinic after accidentally eating a granola bar. The child has stridor, lip swelling, and audible wheezing. Vital signs: HR 148, RR 38, BP 78/40, SpO2 88% on room air. Which intervention is the priority?
- a.Administer oral diphenhydramine
- b.Administer IM epinephrine 0.15 mg
- c.Start an IV of 0.9% NaCl bolus
- d.Apply 6 L oxygen via simple mask
Show answer + rationale
Correct: B. Anaphylaxis with airway compromise (stridor), respiratory distress, and hypotension requires immediate IM epinephrine to the mid-anterolateral thigh. Epinephrine reverses bronchoconstriction, restores vascular tone, and stabilizes mast cells. Antihistamines are adjuncts only and do not treat airway swelling. IV fluids and oxygen follow epinephrine, not before it.
- Question 3 · Endocrine · NGN case study
A client with type 1 diabetes is admitted with blood glucose 612 mg/dL, pH 7.18, HCO3 12 mEq/L, K+ 5.4 mEq/L, and ketones in the urine. The provider orders an IV insulin infusion. After 2 hours of treatment, the K+ is 3.3 mEq/L. What is the nurse's priority action?
- a.Continue insulin and notify the provider for potassium replacement
- b.Hold insulin until potassium is rechecked in 4 hours
- c.Administer 10 units of regular insulin IV push
- d.Encourage the client to drink orange juice with a banana
Show answer + rationale
Correct: A. Insulin drives potassium intracellularly. In DKA, hypokalemia is expected once treatment begins and is life-threatening (dysrhythmia risk) below 3.3 mEq/L. The protocol is to continue insulin while replacing potassium IV — not to hold insulin, which would cause rebound ketosis. Holding insulin without addressing potassium also delays correction of acidosis. Oral intake in DKA is unsafe.
- Question 4 · Neuro · NGN case study
A 28-year-old is admitted after a motor vehicle collision with a Glasgow Coma Scale of 7. ICP monitoring shows pressures of 24 mmHg sustained over 10 minutes. Which intervention is most appropriate?
- a.Lower the head of bed to flat
- b.Cluster nursing care to provide rest periods
- c.Administer prescribed mannitol 1 g/kg IV
- d.Suction the airway every 30 minutes
Show answer + rationale
Correct: C. Normal ICP is 5–15 mmHg; sustained pressure above 20 mmHg requires intervention to prevent herniation. Mannitol is an osmotic diuretic that pulls fluid from brain tissue. Head of bed should be 30°, not flat. Clustering care raises ICP — care should be spaced. Routine suctioning raises ICP; suction only as needed with pre-oxygenation.
- Question 5 · Maternity · NGN case study
A laboring client at 39 weeks suddenly reports severe abdominal pain. The nurse notes dark red vaginal bleeding, a rigid uterus, and fetal heart tones drop to 90 bpm. Maternal vitals: BP 86/48, HR 132. Which complication is most likely?
- a.Placenta previa
- b.Placental abruption
- c.Uterine rupture
- d.Cord prolapse
Show answer + rationale
Correct: B. The classic triad of placental abruption is painful dark vaginal bleeding, a rigid/board-like uterus, and non-reassuring fetal heart tones. Placenta previa is painless bright red bleeding. Uterine rupture typically follows a previous uterine scar with sudden cessation of contractions. Cord prolapse presents with a visible or palpable cord and variable decelerations.

How are NCLEX case studies scored?
Each NGN case study has six sub-questions. Each sub-question is scored independently using polytomous scoring (partial credit). You don't have to answer them all correctly to do well — getting most of them right is enough to demonstrate clinical judgment.
How many case studies are on the actual NCLEX-RN?
Test-takers receive 3 stand-alone case studies (each with 6 sub-questions, so 18 items) as part of their NCLEX-RN. Additional NGN item types — bow-tie, matrix, cloze, extended drag-and-drop — are mixed throughout the remaining items.
How long is each case study on the NCLEX?
Each case study takes most students 5–8 minutes to read and answer all six sub-questions. The total NCLEX-RN window is 5 hours including breaks, and case studies are not separately timed.
What's the difference between a case study and a bow-tie question?
A case study is a multi-question unfolding scenario with six sequential items. A bow-tie is a single question with a three-zone answer format (one condition in the center, two actions on the left, two parameters to monitor on the right). Bow-ties can appear inside case studies as the 'take actions' step.
Are these case studies updated for the 2026 NCLEX test plan?
Yes. Clarity questions are aligned to the NCSBN 2026 NCLEX-RN Test Plan and reflect the post-April-2023 NGN format with the Clinical Judgment Measurement Model integrated.
