I observed something I can hardly believe and don't know what to do. My brother (I am his carer and he lives with me) has just had knee replacement operation. There has been washing regime to prevent MRSA. Head to foot for days. Went for last blood test before op, and nurse, after putting cotton wool on the site, taped it down with some plaster on a reel (like sellotape). SHE BIT IT OFF with her teeth !!!! I can barely believe what I saw, but I'm SURE. He is still in hospital. Reluctant to report in case there are repercussions. AIBU ? Get over it ? YANBU This is outrageous- report it???
