The law and the expanding nursing role.
Nursing has moved through two major phases in licensure. From 1900 to 1938 basic registration acts were passed and amended. In 1938 the goal became mandatory licensure for all those who nursed for hire. This move was linked with the stratification of the nursing role to include both practical and registered nurses. The third and current phase in licensure began in 1971 with the Idaho revision of the nurse practice act; 30 states have now revised their nurse practice acts to facilitate role expansion for registered nurses. Several approaches are being used in these laws including mandating new board regulations, expanding the definitions of nursing; increasing the power of physicians to delegate, and mandating the use of standardized protocols to guide the practice of nurses who are accepting new responsibilities.
