LTC facility, can an LPN adjust TPN? - Page 3

I know at the facility where I work in PA, there are TPN patients that are temporary rehab patients in the subacute rehab section. I am an RN now, but as an LPN student, I was taught LPN's were to have nothing to do with anything entering a central line. I know some LPNs at our facility were doing the TPN. I told them to call me or another RN to take care of it.
