First, review the test blueprint to understand the breakdown of the test as to what areas are emphasized. The blueprint lists the ideal distribution of questions and the number of questions that are included for each client problem and activity associated to it. Questions on the kidney replacement therapies are much of the questions on the test (56-59% currently) but examining a broad overview of nephrology nursing is important. Only you know your strengths and weakness and concentrating on the areas that you feel you are weak helps prepare you to feel more confident. 

Not now, although the Nephrology Nursing Certification Commission (NNCC) board and the CNN-NP board are actively pursuing having this test being recognized and approved for national board certification by the Accreditation Board for Specialty Nursing Certification (ABSNC). 

To the best of our knowledge the CNN-NP exam is not accepted as a source of CEU credit by any State Board of Nursing or other nursing organizations.  It is not accepted by any states as being the only certification required to practice.

The number one reason to become certified is to help ensure patient safety. For the NP who is driven to be certified it is often to fulfill a personal need to be professionally recognized as having obtained a higher level of excellence in their practice.  Putting "CNN-NP" next to your name shows your colleagues that you have the advanced knowledge and competence as a nephrology NP and you provide an excellence of care that is the desired by our standards of practice.
