I have also done research on this topic. I have 4 tattoos and I am in school to be a RN. All my tattoos are in places that are convered by my scrubs
. 3 are butterflies, one on my breast, above my belly button and the biggest is on my lower back. Yes, I do have a thing with butterflies. The other is my initials on my ankle. When my school sent out the information about our clinicals, they included info. on all this type of stuff. Now , my college is very stricted when it comes to do with saftey and presentation. For example, I can not where any rings except my wedding band, only ear-rings in one sent of holes, no necklaces, no nail pollish except clear, no fake nails, no visible body peircing, tattoos, hair is to be worn up, ect. For a long time I have wanted to get a tatto on the back of my neck, but b/c I want to be a nurse, I know that I can't. Of course, if I can find a way to get the tattoo and be able to cover it up, I will. I don't have any body peircings, anymore. Ever since I had my first son, I took them all (eyebrow ring, which I wish I never got the first place, and tongue ring) out.
My suggestion would be to find out what your schools policy is. You can also see what the policies are at the places you want to work. Some places are more strict than others on this topic.
