There is an exemption in the NC Medical Practice Act that allows a non-licensed person to perform certain tasks. This exemption comes at the end of the PA provision exempting PAs (and others) from the practice of medicine (N.C. Gen. Stat 90-18), which reads:
NCGS 90-18 (b) (13) The performance of any medical acts, tasks, functions by a licensed physician assistant at the direction or under the supervision of a physician in accordance with rules adopted by the North Carolina Medical Board. This subdivision shall not limit or prevent any physician from delegating to a qualified person any acts, tasks, and functions that are otherwise permitted by law or established by custom. The Board shall authorize physician assistants licensed in this State or another state to perform specific medical acts, tasks, and functions during a disaster.
