My moms health care aide took my 96 yr old dad to the doctors because of a bad cold,?

dad is severely alzheimered and has absolutely no memory,the dr told him to take his shirt off sos he can hear his chest noises.then my dad kept on repeating why did i see the dr or i didnt see the dr,mostly i never saw the dr.he kept this up all evening long.the aide was getting annoyed with dads behaivior,he will find 9 ways to sunday to bother you with his persistant repitition of things.im aware that my dad lives for the moment,but he can and will badger the heck out of you.
