Hi,
I've never worked in NJ, but have heard from people who've worked there that it's a 'mother, may I?' state.
Here in PA, at least the region where I work, our protocols are exactly the same as the state protocols. Albeit, we do not carry all the drugs on the state approved drug list(thus, we can't give drugs that we don't carry, obviously), but the ones we do, we are allowed to give as per protocol without medical command contact, which is virtually never. A few come to mind in our 'Contact Medical Command' box...dopamine, 1:1,000 epi for asthmatics, third round of adenosine, etc. I find it to be liberal compared to what I've heard about Jersey. Like I stated before, I've never worked in NJ, but I would also find it a pain in the *** to have to call command for many of the things we do not have to call command for.
And yes, we do work EMT/Medic frequently.
