I am a nurse and was one for the last few years as a witness.
The issue of a blood transfusion was never a problem for me as I always thought that I was not the one taking the blood or hadn't prescribed it. The patients I looked after had a right to their decision as much as I had and I was just carrying out another form of treatment.
Even now though I have not been going for 8 years or so I still don't know whether I could accept a transfusion or not, Whether that is my squeamishness or because it has been ingrained so deeply or not am not sure.
Anyone else have these thoughts?
