In California, LVN's are not allowed at all to push any iv medications, or mess with Central Lines. After LVN School, it is optional for the LVN to take a week long class for "Interavenous Therapy and Blood Withdrawl Certification". Even though this is optional, most acute care facilities in CA will not hire an LVN without this certification. So basically, it is to become certified to start, maintain, hang IV solutions/medications and D/C peripheral IV's, by the California Board of Vocational Nursing and Psychiatric Technicians. There are also different levels of LVN's in CA, too, depending on where you work. For example, for the County of Los Angeles, Department of Health Services, an LVN II is IV Certified and works on inpatient wards, and an LVN III is trained to be a Critical Care Nurse..Hope that answers your question JaredCNA.
