I agree that nurses are not medical professionals, and I don't believe I have ever referred to them as such. Graduate nurses have nursing degrees but they and other para-medics do work in clinical settings so they can correctly, in my view, be referred to generically as clinicians / health-care workers / care-givers.*
In the UK (and I think the US & Canada) there is a nursing grade referred to as nurse-practitioners who are trained and licensed to prescribe a limited number of drugs. I don't think we have that grade here yet although nurses seem to be agitating for something like it.
* Wikipedia seems to agree with me here. Be still my beating heart!
