as far as rns and lasers in fl, i wrote the board about 8 months ago asking and they told me i had to be an electrologist. there is no "law" written by the nursing board that says we can or can't. i found a petition from an rn doing laser asking if it was in her scope of practice and the board ruled no. here is the link:
you can also go to myflorida.com do a search for "lasers" and read the minutes from the board of medicine, july and august 2005 discuss laser use. the board of medicine says use of lasers is practice of medicine which only mds, dos, arnp's and np's can do. there was a presentation from an rn who got in trouble for doing lasers who spoke about it.
so then i find out the if i were to get the electrology license that electrologists are under direct supervision of the md (meaning md on site). i wrote the board of nursing asking if an rn with an electrology license would be under direct or indirect supervision. i'm waiting for a reply. i'll post it when they respond.
it seems silly that a properly trained rn can't do cosmetic laser work, when an electrologist with a 2 month degree can!
