In my district mass vision and hearing screenings are performed. Basically 500 students in 2 days with lots of volunteers. Teachers are asked on these days to treat minor complaints in their classrooms but to send head injuries and major injuries to the gym where I am. A student presents with about a 3/4 inch laceration to the back of his head. I take him back to my office clean the laceration and stop the bleeding. Then call his mother to let her know that he slipped in the bathroom, hit his head and sustained a laceration to the back of his head.I asked her to come and pick him up and take him for further medical treatment. It looks to me like he needed stitches? Bleeding was stopped by this point. I escorted the student to the front office, where he was allowed to sit and wait for his mom, who was 10 minutes away. The head injury seemed benign with no s/s of a concussion just a laceration. The policy is that volunteers cannot be left alone with students (even though half were parents). Needless to say I was in a rush to get back to the screenings...Mom complained that I did not monitor her child, even though I called her right away to pick him up and provided what treatment that I could. I was more comfortable letting him sit and wait than dragging him around with me...What do you think?....I am always so offended by complaints. I think my principal knows that I try very hard to keep everything together...Should I have just taken him with me?
