It's my understanding that each and every hospital can make it's own policy as defined by it's risk management department. They do not have to let LPNs administer IV meds. In hospitals where I worked LPNs who administered IV meds had to be IV certified by a preceptor and take a written test. I think the BON policy helps define an individual hospital's policy where LPNs are allowed to perform IV therapy.
