I am a nursing student in my final semester and realize that I have a problem. Sometimes, not always, I have a vasovagal reaction to watching some venapuncture-type procedures. This past weekend I was watching a dialysis shunt insertion and I suddenly got that feeling of lightheadedness, nausea and the need to sit down. I found my way to the other side of the room and found a chair and was ok after sitting a little while. How the heck am I going to be a nurse when this happens on occassion? Is there anything I can do to end the epidose when I begin to feel symptoms besides leave the scene? Anyone else have such issues? Any input would be greatly appreciated!
