Need some advice

Hey all,
I recently accepted a Burn ICU job in NJ. I'm a new grad and if i pass the NCLEX i will start sometime in March.

For the past 4 years i've been an EMT and have a lot of 911 experience under my belt. Reason i took this job is because im a hungry student, and i think it will be an amazing opportunity to learn a lot. Just from interviewing with the BICU manager i was told that i will see multiple problems with pt's (renal, cardiac, fluids, etc.)

The orientation is 4 months, (ACLS, PALS, Disrrhythmias class, and i will be cross trained in all other ICU's in the hospital)

So several people already told me that im crazy for taking this job, that i will burn out, that its going to be really difficult. Now im set in my ways and pretty stubborn and still think that this will be good for me. But in the back of my mind im questioning it as well.

I went for a tanking procedure, just to see what its like. Didn't bother me at all, im used to seeing patients in their worst moments of life. The pt was 29% burns (arms and legs) from "huffing" (sniffing spray pain cans), the stove pilot light caught on and blew up in their face.

I need a burn nurse to level with me, hehe i know im asking for a lot.

Oh and what does the saying "once a burn nurse, always a burn nurse" mean?
