HI! looking to a job description for LVN in san Diego i came up to IV Certification. i have never heard about it? so i was looking in the internet a school or a place where when i have it. does any one know about it. do they have expiration date or something about it. i went to Grossmont adult center they didn't give me much information but it takes 4 month M-F 4 hrs. to take the certification and i thought it is to long.
