Nurse Examination
Written and reviewed by Dana Whitfield, RN, MSN · 4 min read · Updated September 2026
Short answer
The nurse examination that licenses RNs and LPNs/VNs in the US and Canada is the NCLEX, either NCLEX-RN or NCLEX-PN depending on the program completed. It's a computer-adaptive test built around clinical judgment and safe practice rather than memorised facts, and it ends once the algorithm is statistically confident in a pass or fail decision.
The short answer
When people say "nurse examination," "nurse tests," or "the test to be a nurse," they almost always mean the NCLEX — the National Council Licensure Examination. Graduates of an RN program sit the NCLEX-RN; graduates of a practical or vocational nursing program sit the NCLEX-PN. Both are developed and administered by the National Council of State Boards of Nursing (NCSBN) and are the final academic requirement before a state board will issue a license.
The exam uses computerised adaptive testing (CAT), meaning the difficulty of each question adjusts based on whether you answered the previous one correctly. It doesn't test how much you've memorised so much as whether you can make a safe clinical decision with the information given, which is why rote recall alone tends to underperform on it.
The detail behind it
The current NCLEX uses the Next Generation NCLEX (NGN) model, which includes case-study style items alongside traditional multiple-choice questions. Case studies present a single evolving patient scenario across several linked questions, testing the full clinical judgment cycle: recognising cues, analysing them, prioritising hypotheses, generating solutions, taking action, and evaluating outcomes.
The number of questions each candidate answers varies, because the test stops as soon as the algorithm can determine pass or fail with 95% confidence, or when a maximum question count or time limit is reached. This is why two candidates can pass with very different numbers of questions answered; the length itself tells you nothing about your result.
Content is organised around Client Needs categories, covering areas such as safe and effective care environment, health promotion and maintenance, psychosocial integrity, and physiological integrity, with pharmacology and parenteral therapies woven throughout rather than tested as a standalone block.
What this means for your study plan
Because the exam rewards clinical reasoning over recall, a study plan built purely around flashcards or memorised drug lists will only get you partway. Practice questions that require you to prioritise between two plausible actions, or to work through a case study across several linked items, do more to prepare you for the actual test format than isolated fact review.
Build your schedule around the Client Needs framework rather than around textbook chapters, so your practice mirrors how the exam samples content. Weight your time toward physiological integrity and pharmacology, since these carry the heaviest proportion of test content, but don't skip psychosocial integrity or safety content on the assumption it's lighter — it still shows up in every test form.
Use timed practice sets that include NGN-style case studies specifically, not just legacy multiple-choice banks, since the newer item types test a different skill and unfamiliarity with the format costs candidates time on test day.
Related questions people ask
A common follow-up is whether the NCLEX-PN and NCLEX-RN test the same content at different depths, or genuinely different scopes of practice. They differ in scope: NCLEX-PN focuses on data collection and implementing care under supervision, while NCLEX-RN adds independent clinical judgment, planning, and evaluation, which is reflected in both exams' blueprints.
Another is how the NCLEX relates to state licensure once it's passed. Passing the NCLEX is necessary but not sufficient; the state board of nursing still issues the actual license, and separately verifies things like background checks and any prior disciplinary history before a license is granted or activated.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our fundamentals practice questions are the closest set to what this page covers.
Common questions
How many questions are on the NCLEX?
It varies by candidate because the test is adaptive and ends once your pass/fail status can be determined with statistical confidence, or when you hit the maximum item count or time limit. There is no fixed number that applies to everyone.
What's the difference between NCLEX-RN and NCLEX-PN?
NCLEX-RN licenses registered nurses and tests independent clinical judgment, care planning, and evaluation. NCLEX-PN licenses practical/vocational nurses and focuses more on data collection and carrying out care under the direction of an RN or provider.
What are Next Generation NCLEX case studies?
They're a set of linked questions built around one evolving patient scenario, testing the full clinical judgment cycle from recognising cues through evaluating outcomes. They were introduced to assess reasoning across a full case rather than in isolated single-answer questions.
Does the NCLEX test pharmacology separately?
No, pharmacology and parenteral therapies are integrated throughout the exam rather than tested as a standalone section. Expect drug-related content inside physiological integrity items and within case studies, not as a distinct category.
Can I retake the NCLEX if I fail?
Yes, but most jurisdictions require a waiting period, commonly around 45 days, before you can sit again, and there are limits on the number of attempts allowed within a year. Check your specific state or provincial board's retake policy, since it isn't set by NCSBN alone.
