Not sure what programs are offered to train from RN to Paramedic, I guess some of the prerequisites would be the same.
I do not see much common grounds between an RN, regardless of the place of practice, and a firefighter. I am an ICU Nurse and do not see how that would prepare me to be a firefighter at all. Seems that would be a brand new job, requiring new training.
In fact I think that a firefighter would require very rigorous physical work and different critical thinking when compared to an RN.
I see more questions about cross-training from one thing to another, and I am all for advancing in jobs, I myself went from CNA to LPN to RN, and do not intend to step on anyones feet, but I think not every thing can be cross-trained to, make sense?
