Orthopaedic Nurse Practice Test

The Orthopaedic Nurses Certification Exam was designed by the Orthopaedic Nurses Certification Board (ONCB) to provide orthopaedic nurses with the only credential in the field to recognize expertise in orthopaedic nursing. The ONCB’s orthopaedic nursing credential can help you demonstrate your dedication to orthopaedic nursing, or even secure a coveted position in a hospital, clinic, or practice. To earn the orthopaedic nursing credential (ONC), you must take the ONC exam. However, in order to take the ONC exam, you must meet specific criteria.

What are the eligibility criteria to sit for the ONC exam?

To sit for the ONC exam, you must demonstrate two full years of practicing Registered Nurse (RN) experience, and you must hold a full, unrestricted RN license in the United States. If you are an RN in another country (the country in which you received your RN education), you will need to meet equivalency criteria as determined by a number of international credentialing services available via the ONCB website. You must also demonstrate at least 1,000 hours of work within the past three years as an RN in orthopaedic nursing. The ONCB recognizes a number of means of attaining this experience, including adult care, education, emergency room experience, critical care, home health care, pediatrics, administration, and other related areas.

Fees for the ONC exam are $290 for National Association of Orthopaedic Nurses (NAON) members via online application; $315 for NAON members via paper application; $405 for non-NAON members via online application; and $430 for non-NAON members via paper application. Once your application and exam fee are processed, you will receive notice of your exam eligibility period via email and postcard. You must schedule and complete your exam before the eligibility window closes.

What does the ONC exam cover? How many questions are on the ONC exam?

The ONC exam was designed by and for orthopaedic nurses, so you can rest assured that its content is relevant and useful. The ONC exam consists of 150 questions, of which 135 are scored. The remaining questions function as pilot questions that help determine the efficacy of such questions for future use. Because you will not know the difference between scored and unscored questions, it is important that you answer each consecutive question to the best of your ability. You will need to answer at least 97 questions correctly in order to pass the exam.

The ONC exam covers several content areas within two overarching specifications: condition and task. The content areas and number of questions per content area are as follows:

  1. Condition
    1. Disorders, degenerative: 42 questions
    2. Orthopaedic trauma: 28 questions

Orthopaedic Nurse Study Guide – Customer

The study guide had all of the content in it that I needed to learn in order to do well on the test. Once I read through the guide, I realized once I learned the guide, I'd know enough to do very well on the test. It was a relief because I wouldn't have to go through old notes and learn things I didn't necessarily need. Since this guide was made to help those studying for this exact certification, I knew it was the right one for me. I hope that if I have to take any other big tests in the future, I can find study guides to help me that are even a percentage as good as this one. I know I'll face a lot of tests as a nurse and I hope there are other specialized study guides out there. This one sure saved me a lot of time and ensured that I would do well.

Orthopaedic Nurse Study Guide – Horton

Orthopaedic Nurses Certification Exam Secrets helped me to review the major concepts that were covered in the exam. It offered more than just a practice test--it was a real review! Even though I got most of the questions on the practice test correct the first time, I read the explanations as a review, anyways, because I found that the explanations were a good review, in and of themselves. The explanations were far more in-depth than many other practice tests that I have found, which I found incredibly helpful. I would definitely recommend getting this, as well as the flashcards that are meant to accompany the book.
