Most of the time I don't mind too much:). I try to remember that sometimes I call my nurse friends and ask them questions I already know the answer to just because when it comes to your own kids or yourself you become instantly stupid.
I believe that call lights should be set up like PCAs. Hit it once, then you're locked out for a predetermined length of time. There could be order sets for the docs, based on the patient's history of call light abuse.
