I don't really understand why systems would have nurses giving orders anyway. Since I'm not a licensed medical provider I wouldn't feel comfortable having my name on an order anyway, let alone through a phone on a patient I've never seen. I get that these are probably through standing orders or protocols from the medical director, but it just seems weird that one non-LIP is requesting an order from another non-LIP.
Occasionally our nurses may ask for a 12 lead , BGL, specific assessment, and so on (especially for some of the lower acuity/volume services); but we are just discussing an assessment that I would think is beneficial and is within their scope and standing orders already. When we request these though it is in the same nature of a medic asking another medic their thoughts on a case. The moment an EMT, medic, or flight nurse asks for an order I had the phone over to one of our PEMs or adult attendings.
The reality is that most nurses, even those with extensive ED experience, don't really understand the nature of pre-hospital care; especially so in 911 systems.
