Can something be done about the nosey CNAs at a hospital?

Villas - Can something be done about the nosey CNAs at a hospital? You are there to work ladies, not gossip about patients! Cause half the time you are not even close to what it is about. Remember who you're around when you talk about someone. You might be taking care of that person's family member who is awake, alert and orientated. What I heard I let it go, but next time I will report it!
