“This is a great guide. It has just enough information to build your knowledge w/o overwhelming you with unnecessary information.”

– Ali

“After two failed attempts I purchased this book and I was able to pass the OCN. I studied this guide for 6 weeks on and off I highly recommend using this with material from the ONCC.”

– Miranda

“This book was all I referenced after failing the first time I took the OCN exam. Happy to say it paid off!!! This book reviews everything so well.”

– Nicole

“I really appreciate the test-taking strategies as I tend to get anxious when needing to take a test. And I especially like reading the rationales to answers which helps me also retain more information.”

– Jeremi

Recreate the Test Experience in Your Living Room With 3 OCN Practice Tests

Knowledge alone is not always enough.

Nurses will spend hours reviewing the necessary material only to be thrown off by the structure of the OCN. With Mometrix, you don’t have to worry. Our practice tests are accurate, up-to-date replicas of what you can expect on your exam.

We also include in-depth explanations for each answer so you fully understand the logic behind correct choices.

With Mometrix, there are no surprises. Your brain will be primed to ace the exam.

Learn Your Way With Video Explanations

Do you struggle to retain information by sitting in a quiet room and pouring over a book?

No worries, most people do.

That’s why we created comprehensive review videos to go along with the study guide. You don’t have to re-read the same three paragraphs with the hope that this time you’ll magically understand it.

Instead, watch our instructor cover the topic in a way that’s easier to digest, with visual examples and practice questions to make sure you know the topic from every angle.

Think Like a Certified Oncology Nurse

Remember, the OCN is designed to ensure you have the required skills to be an oncology nurse. Good medical judgment is something you’ll be tested on, which throws off even the most dedicated students.

Our guides teach you how to use real-world skills on test day. We’ll help you look for answers that promote healthy patient-practitioner communication and prioritize respecting patients’ feelings. Not only will this set you up to pass the OCN, but it’ll also help you develop the expertise you need to be a top-notch oncology nurse once you’re certified.

Play the Guessing Game Right

There is no penalty for wrong answers on the OCN. While it’s always in your benefit to guess, guessing randomly is not the way to go.

Our guide contains tips on good guessing strategies written by experts with familiarity with the OCN’s structure. From turning multiple choice questions into true or false questions to dissecting tricky language, smart, judicious guessing maximizes your final score.

Guessing can make the difference between a passing score and needing to retake the exam. Mometrix helps you learn to guess intelligently to ace the Oncology Nurse Certification on your first try.

Impossible to Regret: 1-Year 100% Money-Back Guarantee

We’d hate to see you spend hard-earned money on a product that simply doesn’t work for you. If you dislike our guide for any reason, you’re entitled to 100% of your money back, no questions asked.

Customer satisfaction matters to us, so there are no loopholes here.

Get More Than An OCN Study Guide

Bonus #1: Prioritize Your Mental Health

Test anxiety is a real hurdle for many students. You might pass a practice test with ease in your living room only to panic when you’re sitting in the exam room.

Mometrix understands the importance of students’ mental health. That is why we include a bonus section covering test anxiety explicitly. We provide more than boilerplate language and generic tips on staying calm. Instead, we offer actionable, research-backed insight on how to best manage your nerves leading up to and during test day.

Bonus #2: Sharpen Your Test-Taking Skills

Too many students waste valuable time on ineffective study methods that fail to help them retain information. Mometrix won’t let this happen. We include a comprehensive study skills section that teaches you how to study smart to maximize your skills in minimal time.

We’ll cover smart strategies and practical test-taking skills. You’ll learn to eliminate obviously wrong answers, evade traps set by test writers, and read contextual clues to ascertain the right choice. We also teach you to pace yourself on test day, start with easier sections first, and remain calm when you hit snags.

With Mometrix, you’re not just learning the material. You’re learning how to be a better test taker.

I PASSED FIRST TRY

This book reflects the test outline perfectly. it condenses the information and makes it so much less overwhelming compared to the ONS text book— which is a nightmarishly overwhelming to try to read. I solely used Mometrix to read, their practice test book, the free online mometrix questions, the 100 something questions on the ONCC website, and the study guide (practice questions book) that the ONS textbook goes with. I studied consistently for 6 weeks before taking the exam. I passed first try & did so well in every subject category that when I renew, I can do my renewal CEUS in any oncology category I want.

Well-written and concise study guide

IIn addition to several ONCC practice tests that I purchased, I exclusively used this study guide to prep for the OCN exam. I also did the practice tests in this book. The “rationales/answers” provided for each question were really helpful. The book mirrors the content and format of the test, and the study tips are good (answer every question even if not sure, etc). I liked the to-the-point style, but still comprehensive nature of this study guide. I passed the exam in one attempt.

Finally passed

After two failed attempts I purchased this book and I was able to pass the OCN. The book is great in breaking down points and also has an online portion that you can purchase and use through your computer, phone or tablet. (Coupon code in front of the book) 😊 I studied this guide for 6 weeks on and off I highly recommend using this.

A MUST!

I just took my OCN for the first time and passed. This book is a quick summary of all things oncology. It was a great refresher and I learned things I didn’t know. I have five years experience in oncology and I did invest two months for studying. This book is an easy read and has a test at the end that is VERY similar to the actual OCN test. I read this book front to back and I’m glad I did!

Easy to use, concise presentation of knowledge

I was feeling overwhelmed about all the stuff I felt like I didn’t know. This book lays things out in very easy to read and concise pieces. I think spending a little bit of time with this book every day would help anyone be ready in no time.
