I had a patient recently who was actively dying, and during her last few days, she developed petechiae and purpura essentially all over her entire body. It was more than usual, but I know that petechia is very common in the elderly. Her family asked me why it was happening, and I realized that I didn't have a really good answer for them (I'm a relatively new nurse, and I rarely work with hospice or palliative patients). It's because of weakened capillary walls that allow blood to seep through, right? Or am I totally off base?
