What are some good heathcare jobs one can get while taking prereq's for nursing school.?

I am a 22 year old male. I'm finishing up A&P II and all I need now for nursing is microbiology and stats. Question is In my classes nearly half the students are in scrubs and already have some sort of job in healthcare, even the ones my age. I am a server at outback steakhouse and the tips are good but I would like to work in healthcare while in school. What are some job opportunities/ and or programs out there that can get me working (quickly) while Im in school. I'm going to start volunteering soon.
