To properly complete the annual guardian plan, what records must the guardian maintain?

The correct response highlights the critical components that must be included in the guardian's annual plan to ensure compliance with legal requirements and to provide a comprehensive overview of the ward's needs. Maintaining detailed records that encompass dates, names, and addresses of residences, as well as medical treatment information, is essential for several reasons.

Firstly, this information gives a full picture of the ward's living situation and any changes that may have occurred over the past year, which is important for assessing their safety and well-being. Secondly, keeping track of medical treatment information is vital because it ensures that the ward receives appropriate healthcare and that the guardian remains aware of any medical needs or conditions that need attention.

In contrast to the other choices, financial records alone or medical records exclusively would not provide the complete context necessary for the guardian plan. Personal identification documents, while important, do not encapsulate the ongoing care and oversight that a guardian must maintain throughout the year. Thus, the comprehensive nature of the records required in the correct response underscores the guardian's responsibility to monitor and advocate for the ward’s overall quality of life and health.
