I hated and stressed in nursing school because I have a tiny heart on my hand... It is in the bend between my thumb and my pointer finger. Let me tell you, it was the WORST place EVER to have to wear bandaids. ESPECIALLY when I had to change it every time I washed my hands...
Some of my clinical instructors told me to get the bandaids off STAT. If it wasn't covering a wound, the tiny heart wouldn't offend anyone.
Seriously, I don't know why tattoos and piercings have to be deemed unprofessional. I can understand not having so much metal on your head the MRI machine would suck you up from across the hospital. But a few piercings that don't dangle (ripped eyebrow area r/t crazy patient who yanks it out = ouch). No less, I think that unoffensive tattoos shouldn't be an issue.
Since I've been working, I haven't covered my tattoo. Although one of the places I've worked for had a strict no tattoo policy, they even said that it would be better to show then to try to keep nasty bandaids all day.
I do plan on having it removed. Quite honestly, we do live in a society where most decent paying jobs that are common and practical do not allow you to express too much individuality with piercings or tats.
