I gave some thought to applying to UNC's Burn Unit (which, BTW, is Amazing!) recently, but it is exactly the screaming you are talking about that gave me pause. People who work with burn victims have first-class seats going straight to heaven, as far as I can tell. The children in particular would haunt me long after I left the unit.
Take the job - I have my RN as of late June and have been applying to New Grad and regular RN jobs alike since April with literally no bites until today (I have applied to close to 100 jobs at this point, not kidding). The worse the neighborhood, the more complex situations you are likely to see. Eventually, you will probably roll your eyes at every "complex" thing that occurs as you will have seen it all before, but for now it is ALL worthwhile learning. Good luck!
