SOS...School Advice needed

I am living in South America studying English Pedagogy and once I return to the States I plan on studying nursing. My question is, how do I get started? All I know is that I need to start out in a community college, but how do I go about selecting classes, programs, etc? My goal is to become a Pediatric Oncology Nurse Practitioner. What steps do I need to take in order to achieve my goal? Please, I need help. Thank you for your time!
