Which of the following describes a guardian's decision-making responsibility?

A guardian’s decision-making responsibility is fundamentally tied to understanding and prioritizing the ward’s individual preferences and values, particularly in light of their past decisions. By revisiting the ward's past choices, the guardian can make informed decisions that reflect the ward's established preferences and lifestyle, thereby honoring their autonomy and wishes as much as possible within the constraints of their capacity.

This approach is grounded in the ethical principles of guardianship, which emphasize the need to act in the best interest of the ward while considering their previously expressed wishes. In essence, it is about maintaining continuity of care and respect for the individual's autonomy even in situations where they may no longer be able to advocate for themselves.

The other options do not align with the responsibilities of a guardian. Acting solely on personal beliefs fails to regard the ward's interests and values, which is not acceptable. Always consulting the ward personally can be impractical or impossible, especially if the ward has diminished capacity. Making random choices lacks the necessary intention and is counter to the guardian's duty to act thoughtfully and responsibly on behalf of their ward.
