I put in an earlier post that an elderly person's skin is very thin. Nancy had bruising on her arm in one pic. My 92 year old mother had bruises like that and the skin was so thin the bruising would bleed. She would find blood on her sheets (upper part) at times. Also, even the slightest bump on the bruised area would cause it to bleed. Is it blood on the sheets you are referring to?Disagree. Fluids in the bed would raise concern,
