In defense of nurses everywhere, including the ones who were taking care of my aunt while she developed her bedsore, sometimes the patient's condition makes it right next to impossible to prevent these things. I say this as a 'retired' ICU nurse who also worked in home care and saw lots of them.
Bless you, I just got out of ICU, and the nursing care was amazing. I thought I was in heaven. Except when it came time to remove the glue patches for the heart monitor. Took some time because my skin was really sensative, at least they let me do it and didn't rip them off. I think it took me two days in the normal part of the hospital to work them off.
