Marty and Mike, I agree with both of you.
Being hard on someone just because you feel like it is your right is inappropriate. However, as Marty stated, questioning of the newbie to be sure he knows what their doing is acceptable. Both of you state quite accurately, that we as providers have many things on the ambulance that can kill people if not used correctly. That is the job of the senior medic, to make sure the FNG knows and preforms the interventions correctly.
Mike I agree, some people who come into the service with the know it all attitude deserve to be taken down a peg or two. Hopefully most new medics will not exhibit the dreaded Paragod attitude. Remember some of the new medics have been to college for 2 yrs minimum before entering the service. These folks are not idiots. According to the State they reside in and the beloved NR they are licensed/certified Paramedics the same as you. They may be still wet behind the ears as far as field work, but hopefully they have a clue. The Medical director thought so.
