How to lock down a KitKat tablet so public can use but not screw with?

[Texarc]

I have a new droid tablet with 4.4 that I want to set up in my pharmacy as a public medication information source (mounted on a cradle on a counter), with a few apps to allow for drug info, basic anatomy, on the home screen. I'd like to be able to keep kids from jacking it around and loading other things. <g> is there an app for that?

You can make a second user profile and restrict that profile so they couldn't use whatever apps you aren't comfortable with them using
