What sense may still be possessed by unconscious residents?

Unconscious residents often retain their sense of hearing, making it the most likely sense they possess despite their unresponsive state. Research in healthcare settings has indicated that even when individuals are unable to respond, they may still process auditory stimuli. This is particularly significant as healthcare providers and family members can communicate with these residents, as they might still perceive words and sounds around them.

In contrast, while sight, touch, and smell can also be affected depending on the individual's condition, hearing stands out as a sense that often remains functional. Touch may be limited if the person is in a deep unconscious state, and the ability to see would be influenced by the level of consciousness and any medical conditions affecting sight. Smell may also be impaired, particularly if nasal passages are blocked or if the individual is not responsive. Therefore, focusing on hearing is crucial when interacting with unconscious residents, as it creates an opportunity for connection and communication.
