An emancipated 16-year-old patient comes to your office with her 21-year-old sister. Who CANNOT legally sign the informed consent?
Show answer and explanation
Correct answer: B. The 21-year-old sister
An emancipated minor has full legal authority to consent to their own medical/dental care — the 16-year-old CAN sign. The 21-year-old sister has NO legal authority to consent for a sibling — she is not a parent, legal guardian, or healthcare proxy. The question asks who CANNOT sign, and the answer is the sister. Emancipation grants the minor adult legal status for medical decisions.
