Hi CanCan, I think if you really want to work in the OR, you should go for it. I think working hard does not just happen in the OR, RNs in all specialties, and those on the floor also work as hard if not harder. The only thing that I can think that will prevent you from being a very good OR RN is if you are very sensitive to some yelling because sometimes, when surgeons are getting frustrated, they yell. And believe me, wherever you work, there will be surgeons that will yell. It's the way they release stress so don't take it personally. Organization, preparation, and good team work help lessen the yelling, so just try to be prepared, and like I said, don't take things personally. With regards to being smart and strong to be able to work in the OR, I think you are already strong and smart, you are an RN, right? Critical thinking is not exclusively just for OR RNs. Also, hospitals who hire RNs who have no experience in the OR have training programs, they don't just throw you in there and watch you flounder. If you really want to be an OR Nurse, you will learn how to be one, don't be scared. Find a facility that has a good training program and join in. Good luck.
