I've been told that nurses in my district are not covered legally to change a student. If it's a self esteem destruction possibility (and it usually isn't), then I'll assist if I have time. If it happens during recess when the teacher is at lunch, I'll direct him to get his extra clothes, let him use the bathroom, and make sure he gets back to recess safely. But nine times out of ten, the accident happened when the G-tube student needed his fill, the diabetic needed his carbs calculated, kids needed inhalers and other legit visits. So call a para or an aide. I don't like having to blow off a student like that, but I really don't like being put in the position to do that even more.
