Here's the problem with this. Just because someone is limited to EMT interventions and EMT diagnostic tools (however, being in California, I could play word games with how the scope of practice is written in terms of diagnostics. "Evaluate the ill and injured" and "obtain vital signs including, but not limited to" are broad), doesn't mean that the assessment is necessarily limited to an EMT level assessment or EMT level clinical reasoning. If I went back to work on the ambulance tomorrow, even though I would be an EMT, that doesn't preclude me from using techniques such as percussion or considering the medications that the patient is on, even though I didn't learn it in EMT class.
