You can't control the parent's decision so the best way to keep your sanity is to let that fight go. Next step: documentation (document the parent refused, multiple times), education (explain to parent the importance, see if there's a reason such as cost for them not bringing it, offer solutions, educate student (age appropriate) and teachers (what to do if seizure happens, etc.), then document all of that), create your own ECP/provide that to teachers (and document that), call 911 when emergency happens/don't mess with trying to stabilize the student yourself. Community nursing is about being creative with limited resources. Cover yourself with documentation, educate your populus on how to handle emergencies, remember that any student can have an undiagnosed asthma attack/anaphylaxis/seizure -- you wouldn't have medication on hand in that situation either -- so your actions aren't really all that different. I know people want to call CPS when they can't get medication that they feel is needed for the student. However, I have never seen that course of action result in the parent bringing medication to school. Usually that just pushes the parent further from being cooperative OR they withdraw the student/take them to another school. If you do your job well and have the documentation to back up every single effort you put into keeping that student safe, liability should never be a concern.
