What is required for invasive procedures on a minor?

When it comes to invasive procedures on a minor, proper consent protocols are essential to uphold legal and ethical standards in healthcare. A signed consent form from the guardian or parent is a legal requirement that ensures the guardian is fully informed about the procedure, its risks, benefits, and any alternatives available. This not only protects the healthcare provider but also safeguards the rights and welfare of the minor.

Obtaining an authorized signature indicates that the guardian has given informed consent, acknowledging their understanding of the procedure and its implications. This formal documentation is critical in cases where complications may arise or if there are questions about the procedure afterward. The other options do not meet the legal or ethical standards required for consent, making the signed consent form the appropriate answer in this context.
