Final answer:
No formal statement is required for a family member to act as a substitute decision-maker according to the HCCA.
Step-by-step explanation:
According to the Health Care Consent Act (HCCA), the statement about a family member acting as a substitute decision-maker being required to make a formal statement verifying his or her status is false. Typically, a family member who is acting in this capacity will not need to make a formal statement but is expected to follow the rules and principles outlined by the law for making decisions on behalf of an incapable person. For children, it is true that parents can provide consent on behalf of their minor children except in cases where the children are deemed to have the capacity to consent for themselves.
