This is off topic but it may explain the IV thing. I am a medic in the National Guard. The Army trains you to become an NRET EMT-Basic. They also give you more advance training When I work under the ARNG I can do almost anything they say. Example Needle Chest Decompression, I Vs, Draw Blood ETC. In the civilian world with that training I would be EMT-Basic. However some places/hospitals ETC see that I am an Army Medic and allow/expect me to do more. As EMT-B I work under medical control(someone with higher medical knowledge/authority) if they ok it I can/will do it.
