Got an update from the guy in charge of Health of my school district. He said nurses are trained to use AEDs and CPR. They do not have formal training to deal with blood wounds but assures that they would "know what to do. Which is a bullshit answer. So, no, no one on the school grounds in my district has training to deal with any shooting.
I mentioned earlier that a school nurse has a different license then a nurse who might work at a hospital. I wonder if there is a state or national requirement states that a school nurse is required to have the 'public health nurse' and couldn't have school nurse who has a 'registered nurse' license instead. Just as importantly, I wonder if the salary associated with the registered nurse license, or another nurse license like it, would be too much to add to the school's budget and that the chances that that nurse's skills would be required by the school isn't high enough to warrant the cost.
