A nurse hides a surgeon's favorite instrument when a substitute fills in as the scrub. A circulator does not tell a new nurse who is scrubbed that she knows the shunt the surgeon selected has fallen on the floor. A newly hired RN who was previously a scrub tech is shunned by both camps. Is this just life in the OR? Is it part of a nurse's rite of passage? Or is it something more insidious—bullying?
