Someone with psych/corrections experience should have very keen assessment skills to differentiate between a medical versus psych condition-it wouldn't hurt to emphasize this on your interview. Rapid, focused assessments are essential in emergency nursing, as is the ability to multi-task, contantly reprioritize and keep what's left of your sanity in what can be an insane environment.
A suggestion for you is to look at the emergency nursing association's website
www.ena.org to familarize yourself with some of the issues relevent to the ED. If you fit some of the knowledge gained into your interview, it may show a potential employer that you have a grasp of what you would be getting yourself into. Even better, if you find ways to match your experience/talents to specifics involving emergency nursing. Also, you could join the ENA online and go into the interview saying that you were so committed to becoming an Emergency Nurse that you joined-personally, I did this prior to interviewing for ED positions and it worked for me.
Good Luck to you on your search. Let us know how it goes.
PS I just remebered an interview question where I was later told that my answer is what got me the job offer: "What makes you think that you would be a fit in our ED?" "I have an extremely warped sense of humor that doesn't fit in anywhere else"
