In first semester we practiced fingerstick and wheals on each other....the wheals were voluntary. In 3rd semester when we went over IVs, the first day we practiced on plastic arms but the second day we had to do it on each other or we didn't go to clinical. Our teacher said the fear and anxiety we were experiencing was how the patient felt before a procedure and he wanted us to know how that felt and how the anxiety increased waiting for your turn.
