Answers

Claire can be considered a frail adult as she cannot perform the basic activities of daily living.

The frail elderly is defined as one who presents an increase in vulnerability to the presence of stressors, associated with aging, which is characterized by a decrease in the physiological reserve.

Frail adults cannot autonomously carry out those activities that encompass the most elementary and necessary self-care capacities that human beings carry out on a daily basis.

Frailty represents a continuum from the healthy elderly to the extremely vulnerable at high risk of dying and with low chances of recovery.

Therefore, we can conclude that the state of frailty in the elderly is characterized by a decrease in resistance, as a result of aging.
