What is the role of a guardian as defined in the context provided?

The role of a guardian, particularly in the context of elder care, specifically pertains to someone who has been legally appointed to oversee the care and well-being of an individual who may not be able to manage their own affairs, such as a child or an elder. Guardianship involves a fiduciary responsibility, ensuring that the best interests of the person under guardianship are prioritized. This can include making critical decisions regarding their health care, living situation, and financial matters.

In the context of elderly residents, a guardian may be responsible for making decisions related to medical care, residential arrangements, and overall personal welfare, ensuring that their rights and needs are respected. This is different from the other roles mentioned in the choices, which focus on specific aspects of care management or medical provision, rather than the comprehensive oversight and decision-making scope that a guardian provides.
