Hello and welcome to the community.
I think the best thing for you would be to call the state health department for this information. I don't think it should take longer than 5 minutes unless they are understaffed and he is with another patient. Is it possible for you to give her the medication when you are there? Also, you may want to check with state health and the better business bureau to see if their are complaints against the facility. You may need to find a new facility that will take better care of their patients.
Please keep us posted on what you learn and how your mother is doing.
