I know it can be hard to cover up tattoos, but technically employers can't discriminate against you because of our tattoos. You can just make sure they are covered when you go for an interview, so they don't judge you based on that decision. It may seem like you are hiding that from them, but I don't see anything wrong with it. If you end up getting a job then talk to your employer about it maybe? You can also come out and ask hospitals or potential employers if they allow visible tattoos. I know hospitals around here don't allow tattoos to show. I have two visible ones on my wrists, but they are easier to cover also. Good luck. I would still go through nursing school if that is what you really want to do.
