Which of the following behaviors shows evidence of an unstable mental state in an older adult?

Expressing feelings of hopelessness is a significant indicator of an unstable mental state in an older adult. This behavior often suggests underlying mental health issues such as depression or anxiety, which can impact their overall well-being. In older adults, such feelings can arise due to various factors, including physical health problems, loss of loved ones, or significant life changes. Hopelessness can also be associated with isolation or a lack of support, leading to further deterioration of mental health.

In contrast, maintaining consistent daily routines, seeking help from family, and engaging in community activities are all behaviors typically associated with mental stability and well-being. These actions reflect a proactive approach to coping with life's challenges and a willingness to connect with others, both of which are essential for promoting mental health in older adults.
