Can anyone clarify what the rule/law is for live-in home health aides and the dispensing of medication to a senior?

I was wondering if anyone can clarify what the rule/law is for live in home health aides and the dispensing of medication to a senior? Also, are there restrictions on home health aides being able to simply place a call to the pharmacy to arrange home delivery of prescriptions already approved by her doctor that have been delivered for years. We live in LI, NY. This has come up over the years and I would like to get a clearer understanding of the rule. (Mom places the rxs in her mouth by herself, but needs to have it placed on the table to remind her to take it.) Thanks
