The scope of practice concern is what if a code happens. If you in an O.R. the person of contact when something is going wrong is your charge nurse. A nurse not a tech can help run a code and push medications needed for survial. During a code in the O.R. a scrub techs role is to protect the field. Rarely will you meet a scrub tech that has had to give chest compressions and it is out of their scope of practice to push medications per I.V. If I`m in a code situation I would per that the charge is a R.N. The Charge Nurse is more able to adapt to an unusal sitituation. and the Charge Nurse is also in a role to provide resourses for the O.R. staff when differnces occur. I am seeing it more, but why is the question. Scrub tech has a limiited role, outside of scrubbing procedures.
