Agree with the others. Shadow a few times with an OR nurse, and concentrate on what he/she is doing, not the surgery itself. Boring? Let me tell you, there was nothing boring the other night with my patient who showed up in the OR with someone straddling him doing compressions! Granted, that doesn't happen every day (thank goodness, especially since that one didn't have a good outcome), but I have very little opportunity to be bored. I will admit to occasionally having some downtime during the longer surgeries, but I put it to good use- making a list of things that the room needs stocked with, completing some of the yearly required online learning (gotta do it to keep my job, and they'll pay me to do it, darn it!), and very rarely, have a copy of the day's crossword from the newspaper to work on. My particular specialty, open hearts, does have longer procedures as a rule. The rest of the OR? Generally very quick with six to seven surgeries in each room by the time day shift leaves at 1530. Depending on the facility, you may be able to chose the specialty or rotate through all of them, plus with advances in technology, there's always something new to learn.
As for the whole losing skills thing, I completely disagree. You may not get the chance to do certain skills often (IV starts, for example), but you will learn many other valuable skills- how to gain a patient's trust in less than five minutes, quick and focused assessment, and many others. Each area has a specific skills that doesn't necessarily translate to others- as an example, learning how to manage 7 or more patients on a med-surg floor doesn't really translate to OR nursing, where you're completely focused on that one patient.
