I currently have the older editions of the INS Core Curriculum for Infusion Nursing (3rd Edition) as well as the Policies and Procedures for Infusion Nursing (3rd Edition). Also the INS Infusion Therapy in Clinical Practice (3nd Edition). Does anyone know if these texts have been outdated so are no longer a good source for study material for the VA-BC exam? I do have a reference list for the exam and these are not listed. I am trying to save having to buy all new texts. Thanks!
