When I took my then 4-year old to the hospital, the inexperienced young nurse working there forced upon my son an IV to which I refused and then proceeded to ask why an IV was being put in when we were asked to do bloodwork. She then proceeded to tell me that it had to be done and that I was wasting her time. An older and experienced nurse came in and confirmed it was only for bloodwork. Advice - as a patient ask questions, be firm and don't let any nurse/doctor bully you.
