Nurses have played an important role throughout history, and many of made substantial impacts in how healthcare is administered. Before the end of the 19th century, the majority of nursing duties fell to those individuals without any education or medical training at all. It was their courage and desire to serve that made an impact in the medical field, and the early men and women who acted as nurses paved the way for the modern day nursing profession. Today, according to the U.S. Bureau of Labor and Statistics, employment of licensed practical nurses is expected to grow 22 percent from 2010 to 2020, and registered nurses at  26 percent in the same timeframe.
