Now you're talking. I got my EMT-B, worked IFT PT for 6 months, then got into a high paying, well benefitted hospital doing 911 or IFT, depending on the shift. I then chose a 13 month medic course over three years of school for nursing. It was my original intention to do nursing school on a paramedic salary, but I chose to go fire based EMS, where I'm making way more than a nurse. Now I'm completing my EMS degree at my leisure, then my next project is to knock out the RN.
You can do nursing school first and then challenge the medic exam, or do the medic program and then nursing school on a more comfortable income. Perhaps you can also lessen your loan burden or eliminate the need for a loan altogether if you do the medic thing first.
Many will say that you should do the two years for the EMS degree, or just do nursing from the start, and they would be correct from an education standpoint. Your medic program may be stellar, or it may just be a quickie mill that only cares about your money and if they can get you to pass the state and NR exam. Regardless, only you know if it would be better in your situation to do things the proper way where education is concerned, or to do what's the most economically advantageous for you.
One thing though, many have became medics with the intention of going back to school afterward. Many say that they'll take a year off of school since the program was so rigorous and time consuming. If they're paid well, or if the OT is copious, it's easy to get comfortable living on a medic's salary. If you need extra funds, you'll just work a side job and/or OT. "I'm almost making as much as a nurse, and I'm making more than them if I just do one OT shift a pay period or a few shifts at the IFT side job." The next thing is to say that you'll put off school maybe another year so that you can save for a house. Maybe I should go back to school, but the OT's been great, and I'm really racking up! If I go back to school, I'll be giving up all that extra income. Or maybe you have an expensive car to pay off, or just ran up some bills, then you have a kid, get married, whatever order that may be, etc. Now you're stuck, and have no choice but to keep working 60-80 hours or more as a medic as a matter of necessity. The money is just good enough to keep you from having to go back to school.
This is typically how many in EMS get stuck there, never to return to school. Don't fall into that trap.
