I found this on a website for you:
It is not sufficient to complete a course in nursing in order to practice nursing and get employed in the community. An individual who graduates from a nursing program
must pass a mandatory regulatory examination given by the state in order to safely practice nursing. As soon as one passes this regulatory examination, a license is issued and ones name is kept in a registry thus, a registered nurse (RN) title can now be attached to ones name.
The second part of ones journey as a nurse is to gain more experience to qualify to take another set of examinations that is psychometrically sound and specialty –based. This is a voluntary standardized examination given by an accredited credentialing board or organization validating expertise in a designated field of nursing. Once an RN passes this examination, one is now a Certified RN in that particular specialty thus a letter C or BC (board certified) can now be used with the RN title.

Here are some of the most popular specialty-based certified nurse initials other than
RNC or BC:
CCRN - certified in critical care
CNOR -certified nurse in operating room
CIC - certified in infection control
CAN - certified in nursing administration
CNAA - certified in advanced nursing administration
CNE - certified nurse educator
CRNA - certified nurse anesthetist
