A 79-year-old client resides independently in the community. The visiting home health nurse finds that despite it being 90 F outside, the windows are closed, and the client is wearing a sweater. The nurse initially recognizes that this behavior may be related to:

Cognitive changes that diminish the individual's awareness of temperature changes

A delirium-related acute illness that is affecting body heat production

Age-related motor deficiencies that result in self-neglect

Age-related neurosensory changes that diminish awareness of temperature changes
