In Texas at my job we follow Texas Administration Code 225, which is the same for school settings. You can delegate inhalers, etc. The order must state when it is to be used. Then the delegating RN must ensure the unlicensed staff know the signs and symptoms as well as when to call 911, etc. I delegate unlicensed staff to do g-tubes, insulin, all medications, PRNs, and more for group home clients.
