Sort of. Place needle in vein like usual (might be holding the catheter differently compared to a butterfly). Hold needle still, thread catheter off. Tamponade vein, remove catheter, place tubing on hub.I am in Ultrasound school right now and it is not enough for me. I go into the MA lab and practice drawing drawing blood on my best friend. I know IV is much more difficult considering all the variables. My question is are the mechanics the same? If I can draw blood do I have a basic understanding of an IV?
