The nursing profession is both financially and personally rewarding. The decision to become a nurse is one that should not be taken lightly because it requires a lot of sacrifice, honesty, and commitment during and after the educational process. The word nurse means “to nourish”, so nurses are depicted as one who nourishes, protects, and take care of the sick, and injured. The American Nurses Association defines nursing as the promoting, and optimization of health and abilities, prevention of illness and injury.
