If air temperatures exceed what degree Fahrenheit, all resident-accessible areas must be cooled?

The correct temperature threshold for initiating cooling measures in all resident-accessible areas is 85°F. This standard is critical for maintaining the health and safety of vulnerable populations, especially in nursing home environments where residents may have limited ability to regulate their body temperature or respond to heat stress.

Temperature control is essential in long-term care settings to prevent heat-related illnesses, which can be particularly dangerous for elderly individuals or those with certain medical conditions. By ensuring that air temperatures do not exceed 85°F, the risk of heat exhaustion, heat stroke, and other heat-related complications can be significantly reduced.

The other temperature options suggest limits that would not adequately protect residents from the adverse effects of high temperatures, reinforcing the importance of maintaining a cooler environment in care facilities.
