Typically, nurses who pursue a master's degree in nursing become nurse practitioners.
A Nurse Practitioner (NP) is a registered nurse who has completed specific advanced nursing education (generally a master's degree or doctoral degree) and training in the diagnosis and management of common as well as complex medical conditions. Nurse Practitioners provide a broad range of health care services. Nurse Practitioners are considered "Mid-level Providers/Practitioners," along with Clinical Nurse Specialists, Certified Nurse Midwives, Certified Registered Nurse Anesthetists and Physician Assistants. Nurse practitioners, along with other advanced practice nurses, function within the scope of their state's nurse practice act and have varying levels of physician collaboration or supervision. In some states, nurse practitioners function independent of physician involvement.
