Registered Nurses are the largest health care occupation. More than two million jobs are currently held in this field. Projections indicate this field will have the largest numbers of new jobs as compared to other fields. Earning potential is excellent, especially among advanced practice nurses, with additional education and training.

Nurse practitioners are registered nurses (RNs) who have attained advanced expertise in the clinical management of health problems. Typically, the education of the NP is at the masters
level with advanced clinical preparation beyond that of the basic registered
professional nurse.
