Which of the following is NOT a convention for ADL/IADL items on the OASIS?

The chosen response is correct because option B suggests that the availability of a caregiver should influence the response to ADL (Activities of Daily Living) and IADL (Instrumental Activities of Daily Living) items. However, OASIS guidelines instruct assessors to evaluate an individual's ability to perform tasks independently rather than factoring in whether a caregiver is available to assist. This approach allows for a more accurate assessment of the individual's functional status and needs, which can significantly impact care planning.

In contrast, the other conventions are integral to obtaining consistent and valid assessments. Selecting responses based on ability rather than preference ensures that the assessment reflects a person's functional capacity rather than their personal wishes, which could alter their performance if they had a choice. Understanding the specific tasks included or excluded in each item provides crucial context for correctly interpreting the assessment. Lastly, the guidance to respond based on the day of assessment promotes accuracy, as individuals may have varying capabilities on different days. Thus, these conventions help create a standardized approach to assessing ADL/IADL items in OASIS.
