Hi there! I had similar concerns with starting clinicals. My fiancÃ©e is a professional tattoo artist, and needless to say, with free tattoos at my disposal, I have become quite covered. A full sleeve on both my left arm and both legs as well as a small one behind my ear. My school is strict. No visible tattoos is the policy.
That being said, I knew early on I would have to find ways to cover them. Tattoos, at this point in time, are not considered "professional" and I strive to be as professional as possible when it comes to my career. In fact, my goal is to never let anyone at nursing school see my tattoos. period. I don't want people's closed-minded ideas about tattoos to ever affect my learning opportunities. I would hate to, for example, be working at a nursing home, and offend a patient with my choice of body art. I understand it's not everyones cup of tea.
By far the best product out there, in my opinion, is the tat2x sleeves. They are similar to tatjackets, but way more comfortable & lightweight. They cover from armpit to wrist in my case, or they also make ones that are specifically for half sleeves. They come in skin tones and colors.
I like this option more than long sleeves because I get hot and having the added weight of a long sleeve shirt didn't seem appealing to me.
Also for the tattoo behind my ear I purchased some "Amazing Cosmetics" brand concealer. It goes on thick and holds up to heat and movement if you set it with a light finishing powder. I think that is way better option for me than the band-aid one.
Good luck to you in your program. Tattooed nursing students, unite!
