How Long Does the CNN Take?
The CNN exam is a fairly lengthy and difficult exam so make sure you are well-rested, have eaten a full, nourishing breakfast, and are as relaxed as possible on test day. You should be prepared to spend about three and a half hours at the testing center (more if you opt to take the paper and pencil version of the exam).
This includes about 15 minutes to check in before your appointment, three hours for the test itself (or four hours for the paper and pencil version), and about 15 minutes after the exam to go over any questions or concerns you have after the test.
What Skills Are Measured on the CNN Exam?
The 175 multiple choice questions (200 for the paper and pencil version) on the CNN exam will be divided into five distinct content areas including concepts of kidney disease, hemodialysis, peritoneal dialysis, transplant, and acute therapies. Within those five content areas, you’ll need to respond to questions that measure the following skills and knowledge:
- Recognize the pathological processes and complications associated with kidney disease as well as its treatments – 31-32 Questions
- Principles of infection control and the application of those principles – 28 Questions
- Select the appropriate interventions based on the pathological process or complication –26-27 Questions
- Select the appropriate action for administering medication to a patient being treated for kidney disease – 21 Questions
- Physiological and technical principles of renal replacement therapies as well as the application of those principles – 17-18 Questions
- Teaching and learning strategies for education clients, families, other health professionals and the public – 17-18 Questions
- Understanding the importance of using an interdisciplinary approach to promote optimum functioning across the continuum of care – 11-12 Questions

- Determine the most appropriate interventions based on psychological and sociocultural effects of kidney disease – 10-11 Questions
All estimates for number of questions are based on the computer version of the exam. There will be a couple more questions added to each of the above points for the pencil and paper version.
