Another ANP here. I thought about the same thing! Took me ~6 months to even find a job. They even offered to pay to send me back to school, but i declined as I did not plan on staying with that employer.
Sounds funny, but I've heard the saying when you take a job, do so with the consideration of where you are headed next, ironic, but that's how it worked out for me. Even now, in my second job, I think about and plan for my next job even though I have no idea where or who I want to work for.
There are jobs out there for ANPs. Internal Medicine, Cardiology and Endo are huge and going to get larger over the next 10-20 years, not to mention the amount of NP retirements coming soon.
In a burn unit, I think your skills would be in high demand from either the Trauma or Plastics side. Sounds like you work for a larger, metro medical center. There has to be a ton of NPs and you might find that its "who" vs "what" you know that matters.
