The OR is a completely different environment than med surg, ER, or any other area. I started work in the ER straight out of nursing school. .My next job was in home health. Then I ventured into the world of the OR. Oh yeah, the OR is an entirely and completely different world separate from all others. You either hate it or you love it. Without experience, you won't be on your own. A general rule of thumb, is that most will not be entirely comfortable for about one year. Sometimes I felt as if I was losing all my nursing skills, but on the other hand, I gained OR nursing skills. If you don't have "thick skin," you'll grow it. When I started, I was much quieter and not so sure of myself. When I left, I was much more outspoken, way more self confident, and no longer a door mat (so to speak).
