I know you'll be able to work in the OR w/an ADN....I am. Most hospitals will train you to scrub and circulate.
The hospital where I work uses RNs to circulate, no scrubbing at all. Fine with me, though....saves back and knee trouble later.
Good luck w/your ADN program!!!! Let us know how you're doing.
Don't get discouraged...most ADN programs don't teach a lot about the OR. Just be patient and you'll get through your rotations.
