The job description of a Registered Nurse seemed hard to write in a couple of sentences. A nurse has the ability to do so many different types of jobs. On collegeboard.com, I believe the description sums it up nicely.
"RN's care for the sick and injured and help people stay well. They are typically concerned with the 'whole person', providing for the physical, mental, and emotional needs of their patients."
At salary.com, anyone can look in specific areas of the country to show the average pay for nurses. Salary ranges between $38,000-$44,000 in the Gainesville, Fl. region.
