First things first! Congrats on choice of your career that means somewhere you are inclined towards helping others. Really seeing the pathetic situation of different hospitals either private or government ones, this evolving field is really needed nowadays.
After completing the course from a recognized University you can work as Director of Nursing or Chief Nursing Director, Hospital Administrator, Hospital Chief Financial Officer, Health Care Actuary and go to the top as Hospital Chief Executive Officer (CEO) one day.
Remember your efficient management clubbed with proactive strategy can save a lot of lives.
