A limitation of the Katz Index of activities of daily living (ADLs) is that:
a. completion of the tool requires the joint efforts of the interdisciplinary team.
b. all ADLs are weighted equally.
c. it puts a heavier weight on the cognitive abilities necessary to perform ADLs.
d. it provides a range of performance for each task.
ANS: B
The Katz Index assigns an equal weight to all of the ADLs, and because of that, it cannot be used to identify the particular area of need or change in any one task. Any health care profes-sional can complete the Katz Index, although input from the interdisciplinary team is valuable. The Katz Index does not address the cognitive abilities necessary to perform ADLs. The ADLs are considered in dichotomous terms only, the ability to compete the task independently or the complete inability to do so.
