According to regulations, what must be included in the resident’s record at admission?

The correct choice is the documentation of the facility's policies, which is essential to include in the resident's record at admission. This documentation ensures that residents and their families are informed about the facility's operational guidelines, including rules, regulations, and procedures they will be expected to follow during their stay. This transparency establishes a clear understanding of the environment and assists residents in aligning their expectations with the facility's framework.

In contrast, while emergency contact information is important for safety reasons and responsiveness, it is not mandated specifically in the context of what must be included in the records at the time of admission per regulatory requirements. Census data, which pertains to broader statistics and trends within the facility rather than individual resident records, does not carry the same relevance to the admission process. Personal history may provide useful context regarding a resident's background and needs but is typically considered supplementary information rather than a regulatory requirement for admission documentation.
