Sorry that happened but we all know that is exactly the big WHAT IF and the main reason we are all here. (Even though we all really know it's about mounds of paperwork
I think you having tunnel vision on the student is EXACTLY HOW IT SHOULD BE. Good job school nurse!
I am so glad you have a strong clinic assistant. I do too and it is such a blessing.
I definitely think a written plan as well as a meeting with all the other adults about how it should happen versus how it actually happened would be perfect.
I have had the same issue with admin and other adults acting in the most unhelpful ways during an emergency. I have tried to go over the fact that in an emergency they should each have a defined role and that I DO NOT HAVE TIME to give them step by step directions or answer each and every one of their questions. Why would hypoglycemia lead to seizures is a fantastic question but let's cover it later shall we?
So far, my instructions have fallen on deaf ears. I get that they aren't medical people and don't know how to stay calm, cool and collected through a really scary situation but still....
Good luck. I hope you can make some progress.
