Hi, Ive been accepted at the community college and plan to become a RN then depending on 2015 either go for DNP or my Masters to become a NP. My question is while researching the occupation and all the ins and outs I read that Iowa (were I live) np's may prescribe controlled subtances and so on with a DEA number. All RX companies say you must have a medical directors signature on the authorization paper for it to be legal. My question is if you start your own practice since iowa allows NP's freedom without a physicans supervision (although recommended) who would be the medical director of your own practice? I apologize for the dumb question im just not very familiar with the medical field YET.My example is for a vial of Lidocaine in a clinic setting to remove a wart or suture a small laceration who is the person who would order said RX to be stocked in your clinic? Any help would be most welcomed as the laws on becoming a NP seem rather clear but the RX portion seems rather confusing.
