How do I determine if I am eligible to take the CMSRN exam?

To determine if the CMSRN exam is a good fit for you, review the Exam Blueprint, especially the Domains of Practice. The Domains list specific activities that medical-surgical nurses perform. 

If these activities describe your RN practice, then you are eligible to take the CMSRN exam, as long as you meet the practice hours and years of experience.
