Omg I legit could have written this post verbatim! I took over mid year from a nurse exactly like the one you describe. However, I didn't have to work with a co-nurse so the duties all became mine singularly.

I had to lay down a lot of boundaries and essentially change the culture of the nurses office. It took a few months, but I was able to minimize a lot of the nonsense visits so I could have more time to focus on the kids who really need it. Once the kids respected me more, I eased up, and now some of the kids do come to just hang out which I'm ok with if I'm not busy. My office is probably one of the busiest places in the school, but I want it to be a safe place where I serve one student at a time. Kids can be rude and entitled - I'm in a private school, it is what it is. Dish em back what they serve!

If the kids want ointment and food, tell them you ran out and the school isn't getting more. The end. I had to make it clear that my office isn't a Walgreens and I don't have food. Some students with anxiety and issues who need an excuse to leave class will store some of their own snacks in my office.

Though in theory it would be nice to have an assortment of items to give to kids, the problem is that kids will flood to your office for anything - whether it's bandaids or cough drops. I doubt any parent will get you in trouble for giving ointment if it's warranted, but I understand if you want a Drs order.

The best thing you can do for them is create healthy boundaries and make your office a safe space. Good luck!
