A non-English-speaking patient comes with her 12-year-old granddaughter who speaks English. What should you do?

Using a 12-year-old minor as a medical interpreter is inappropriate — minors may lack vocabulary, may filter/interpret incorrectly, and places inappropriate burden on the child. HIPAA and ethical standards require a trained, competent interpreter. Staff may have language barriers and aren't formally trained. Professional interpreter services must be arranged.
