Naxlex NCLEX-RN Review: How to Use the NCLEX Predictor, CAT and RAT

Short answer

Naxlex NCLEX-RN review combines topic practice with three exam simulations: the NCLEX Predictor (85–150 questions, full results report), NCLEX CAT (adaptive difficulty) and NCLEX RAT (60 questions in 90 minutes). Use topic quizzes to learn, CAT to build stamina, RAT to check readiness by subject and the Predictor as your full exam rehearsal.

Key takeaways

  • Practice by client-needs area first, then move to mixed and adaptive sessions.
  • NCLEX CAT adjusts difficulty to your answers, much like the real exam's adaptive format.
  • NCLEX RAT gives a 60-question snapshot across subjects in 90 minutes.
  • The NCLEX Predictor runs 85–150 questions and ends early at 85 when performance is clearly strong.
  • You can exit any simulation and resume later from the same question.

A 6-week NCLEX-RN review plan on Naxlex

Adjust the length to your test date, but keep the order:

  • Weeks 1–2: one client-needs area every two days — lesson, 30-question quiz, full rationale review.
  • Week 3: Next Gen case studies daily, plus pharmacology and lab values review.
  • Week 4: NCLEX CAT sessions every other day; flashcards on missed topics in between.
  • Week 5: NCLEX RAT, then targeted practice on the two lowest subjects.
  • Week 6: NCLEX Predictor early in the week, review every missed question, light review the last two days.

The NCLEX Predictor

The NCLEX Predictor is the full-length rehearsal. It draws questions from all eight client-needs areas, including chart-based items with nurse notes, vitals, history and physical, labs and prescriptions. It runs between 85 and 150 questions and can finish at 85 when more than 90% are answered correctly.

When you finish, you see your overall result, every missed question with its rationale and a breakdown of weak areas. Treat it as a map of what to study next. Take it after you have covered every area at least once, and space attempts two to three weeks apart.

NCLEX CAT

Computerized adaptive testing chooses the next question based on how you answered the last one. Correct answers bring harder questions; incorrect answers bring slightly easier ones. NCLEX CAT on Naxlex uses the same idea so you get used to questions that feel hard — which on an adaptive test is usually a sign you are doing well.

Use CAT for stamina and for practising calm, steady pacing. Do not change answers without a clear clinical reason.

NCLEX RAT

The NCLEX RAT is a 60-question, 90-minute readiness test across subjects. It is shorter than the Predictor, so it works well as a mid-plan checkpoint. The timer counts only the time you are actively on the test, and you can resume a saved session.

How to review results so they actually raise your score

Use the same four steps after every quiz or simulation:

  • Sort missed questions by topic, not by date.
  • For each one, write a single sentence: the cue I missed was ___.
  • Study the lesson or flashcards for the two weakest topics.
  • Take a fresh quiz on those topics within 48 hours. Naxlex always gives you new questions, so the score reflects real learning.

Practice questions with rationales

Original NCLEX-style questions. Choose an answer to see the rationale.

  1. 1. A client receiving a heparin infusion has an aPTT of 120 seconds (control 30). What is the nurse's priority action?

    Answer and rationale

    Correct: B. An aPTT far above the therapeutic range (usually 1.5–2.5 times control) means bleeding risk. Stop the infusion and notify the provider. Protamine sulfate, not vitamin K, reverses heparin.

  2. 2. A client with heart failure gains 1.5 kg overnight. What should the nurse assess first?

    Answer and rationale

    Correct: A. Rapid weight gain suggests fluid retention. Crackles in the lungs show pulmonary congestion, which affects breathing — the priority.

Frequently asked questions

How many questions are on the Naxlex NCLEX Predictor?

Between 85 and 150 questions.

Can I pause an NCLEX simulation?

Yes. Choose Exit & resume later and continue from the same question.

Is the NCLEX Predictor for PN too?

Yes, there are RN and PN versions.

Will the Predictor repeat questions I've seen?

No. New attempts use questions you have not answered before.
