Yes, there is. But is a horrible choice for any medic who does not have significant in-hospital experience, and I don't mean as a simple ER tech. There is actually very little crossover education between the two jobs. So, except for already having your support courses out of the way, there is no significant benefit to being a medic before being a nurse. They are usually very separate career paths for a good reason. They really are not very similar at all. Any one who tells you different has not been both a medic and a nurse, and in that order.
Most "bridge" programmes are community college based, not university based. Consequently you start off behind the 8-ball even if you manage to graduate. They get you through a little bit faster, but usually because they cram, not because they cut back much. And it still takes you at least two years to get all your support courses done, if you didn't do so in your paramedic programme. So, if you just get the cheap and quick paramedic certificate instead of the degree, then you don't save any time at all.
Bridges are a desperate concession in a vain attempt to help make money for community colleges, not a genuine effort to educate competent nurses. If you're not concerned with competence, then go for it. But most all of the grads I have worked with had gaping holes in both their knowledge and competence, because years as a medic left them with the mistaken impression that we don't need all that book learnin', so they don't commit to it.
If you think you may want to do both, then it is absolutely certain that going to nursing school BEFORE medic school results in a much better provider than the reverse. Not to mention the difference in job opportunities. Most EMT grads find they cant get an EMS job even if they do become a medic, as your schools are cranking out hundreds more grads than there are jobs in the area. Don't expect to hear that truth in the school catalogue. It's our dirty little secret. Do some serious job market research before you commit. Even if you can get an EMS job, chances are that it's neither stable nor well paying.
