The epi is there to be used by trained medical professionals. If a person had anaphylaxis I would have given the IM dose. That said, my training as an RN includes ACLS and BLS/CPR. IV medication administration is all by protocol, which is overseen and approved by a physician. In this case I would have performed BLS/CPR and used the AED as there is no requirement except for training. Pushing IV medications without a physician is what I would consider outside of my nursing scope of practice. It would have been possible for the pilot to contact the emergency medical team on the ground. In that case, I would have been comfortable taking orders from a licensed independent medical provider via phone/radio and would have administered the epi IV as/if directed.
