non medical personal care services ??? from RN

Hi Nurses, I am working for 2 Personal care agencies, one does home health as well, but I just do the pcw side. I take vitals signs at the intial visit and super isory visit for one, the other says we are not to do that due to the ct being non medical. How does your agency work? I also have nurses notes for one agency and not the other. Any thoughts??? An RN is required to do the screening for ADL assistance at the home and f/u every 50-60 days there after for supervisory visits. Can any nurses working within this role share their responsibilities?
