About the Online Practice Exam

The purpose of the CDN Practice Test is to allow candidates for the CDN examination to practice with a test similar in content and format to the actual CDN examination. However, no questions on the CDN Practice Test will be on the actual CDN examination. Taking the CDN Practice Test is not required and does not guarantee a similar result on the CDN examination.

The fee for the test is $50. The CDN Practice Test contains 50 multiple-choice questions available in two modes: Practice Mode provides the correct answer and rationale after each question, while Test Mode holds the results until the end of the test. Both modes at the end of the test provide a Score Report which displays your score and breakdown of percentage correct in each area of the test blueprint. The actual CDN examination contains 150 questions in three [3] hours and requires a correct response rate of 73% correct to pass.

You will have access to the test for 90 days. Several scrambled versions are offered for retesting. Your credit card payment will be processed on-line and you will be granted immediate access to the CDN Practice Test.

Emotional Preparation

Moderate anxiety is normal and may be helpful - you may be more alert and open to learning; however too much anxiety is detrimental and will interfere with learning and test-taking.
Study and prepare for the examination so that you feel confident.
Think positively - you possess a wealth of experience and the examination will allow you to demonstrate that knowledge.
Use anxiety-reducing strategies:
- relaxation response.
- guided imagery.
- exercise.
- prayer.
Even though some test takers may finish the exam early, use as much of the allotted time as you need to think through and answer the questions.

Physical Preparation

Get a good night's sleep.
Eat before the examination - those gray cells will have glucose available when you're answering questions.
Gather all the materials you need to take the test the night before the exam:
- government-issued photo ID.
- nursing license.
- examination permit.
- sweater or jacket in case the room is cool.
Allow plenty of time to arrive early.
If you are distracted by other candidates during the test or leaving to use the rest room, select a seat at the front of the room where you will be less likely to notice the other candidates.

Tips on Answering Examination Questions

Read the questions carefully and focus on key words in the question such as "first", "most likely", "most important", "best". These words are usually printed in boldface type to attract your attention.
As you read the question, anticipate the correct answer.
Read each of the four choices carefully. Even if the first option sounds correct, read all options before choosing the answer.
Do not "read into" the question. Answer the question based only on the information presented, even if you think the answer is too obvious or too easy.
Do not be afraid to change an answer. Research has shown that more often than not, test takers change answers to the correct one.
Do not spend too much time on any one question. Make a note of the questions of which you are uncertain and return to them later if you have time.
If you are unsure about one of the content areas, you may find it helpful to complete the other areas first and leave the problem area for last.

"Being certified says to my patients and colleagues that I'm vested in my patients, our program and the staff that I help train and mentor. As a nurse, I'm ethically committed to keeping myself educated and informed as I provide care to renal patients."
