SPIKING BAG= go to the shelf, pick the primary bag, pick the drug, stick the spike into the bag, mix premeasured correct chemical into known volume primary IV solution (a premeasured and strictly mechanical act), then hang it or pass it over or whatever. If you can read and keep your cool anyone can do it.
DRAWING UP A MED: right med, right time, right dose, right patient, right route, and all that? Requires measurement and decision-making, unless it is a premeasured med and it is in only one form and dose on the vehicle.
A pharm tech could under supervision. A paramedic could because their training includes drugs, measures, and admin, and because the paramedic will also be giving it.
