Are registered nurses the same as nurses?

A registered nurse is the basic level attained after graduating from a certified Associates or Bachelors nursing program. This means that the registered nurse has not yet specified if he or she would like to enter a specialized field in nursing. A pediatric nurse is a registered nurse trained in the care of newborns and children. It is a specialized field that a registered nurse must first train on before he or she is able to work in that specific area.
