We had discussion at work last night about what LPNs responsibilites are as far as giving medication after RN signs it off on MAR. The other RN working with me scolded the LPN because she gave a dose of Potassium without looking up the patient levels. The LPN protested that the fact that the Potassium was signed of on the MAR indicated these things had been checked. I personally think that keep tabs on labs is in the realm of the RN. It might be good idea for LPN to have quick look but I doubt if her license would be in pulled if she gave a dose of Potassium to a patient that had K level of say 7. The RN that signed it off would most likely bare the brunt. The other RN disagreed she said they would blame the RN and LPN. I just don't know.
