When I was an ER nurse I did conscious sedation. I pushed morphine and versed for the ortho docs while they were setting bones and casting. This was at a children's hospital. I was under their direct supervision, but I was the one who drew up the drugs and mixed them with saline to be 1:1. I was a nervous wreck the first time I did it on my own (without another nurse supervising). This was after I had passed my PALS certification. After that, I had no problems with doing it. But, I am happy with my job now and would never go back!
