Why?Ignorance?A shortage of syringes?Stealing them for resell or drugs?
It's hard for me to believe that a person with a nursing degree would be so ignorant that they wouldn't know the dangers of reusing needles, or that they are knowledgeable but are unbelievably lazy. I have a health education degree and have worked in hospitals in the midwest and on the West coast, and I have never seen anyone ever reuse a needle or use an unsterile technique.
Despite the odds, the follow-up is necessary. Good for coming clean.
Medical mistakes kill over 200000 people in the US every year according to MSM. Chances are your local hospital won't divulge their number.
