As a former medic and current ER nurse, I can tell you that you can do both. I am actually about to start back with getting my EMT-B since I was silly and let everything lapse several years ago. I am going back to get my EMT and then my paramedic so that I can do flights. I've worked in the ER for a few years now and plan to transition to the ICU in a year or two. 1) I started in EMS because like all, I wanted to help people. I had a friend in high school who told me about becoming a junior member, and it sounded fun and cool. 12 years later, I'm still in emergency medicine. 2) I regret letting my certifications laps when I was younger. I moved to Colorado where EMT-I/99 wasn't really recognized and so I gave it all up for nursing. While I absolutely freaking love being a nurse, I miss EMS and being out in the field more. 3) If you continue and get your P, get your RN, the opportunities are endless. There are always jobs out there for either one, and especially for both. You could do flights, you could work in a trauma center, you could work in ground transport, you could do anything really. Good luck and like Mike said, keep getting the pre-req's for nursing while finishing your EMS stuff, you'll thank him for that advice at some point.
