Would it be ethical for a certified medical assistant to give advice to her own family members?

Very unethical, just think about it. You diagnose say your mum with an STD, then you go home, and everyone wants to talk about it. What happens to doctor-patient confidentiality? YOU as a medical professional cannot talk about it, but as a family member you can. Meaning you are left in a sort of limbo, you can but you can't. Plus, you are stuck between a rock and a hard place, what if you diagnose, god forbid, something awful in one of your family members, something that once you tell them, they wish you didn't know about? Plus, if you misdiagnose do you really want to be put in to a law suit between you and a family member?
