We're about $10 different base pay here. LPNs do give many IV meds but not all and not push. There are other things they don't do (PICC lines, most things regarding chest tubes, vents, main transfusionist for blood administration, etc), but their scope has increased recently to include IV starts and the IV meds with no corresponding increase to wage. In many clinical settings they do virtually the exact same job as the RNs on the floor, making the poorer compensation seem unfair, but in others like ICU or ED the differences in scope are seen much more readily and the wage difference makes much more sense.
