Beyond r.n. is a blog with information for registered nurses about where they could take their career. There are many ways you can further your career as a nurse and this site will explore many of those options. Two of the most common careers for nurses to work towards are a nurse practitioner (NP) and a certified registered nurse anesthetist (CRNA). A NP can diagnose and treat medical conditions similar to a physician. A CRNA can provide anesthesia to patients. Both careers require masters level schooling and training programs.
