Final answer:
The term for the combination of physical, emotional, and mental exhaustion caused by sustained stress is Burnout, which includes feelings of exhaustion, emotional detachment, and a negative self-view towards personal achievements.
Step-by-step explanation:
The term used to describe physical, emotional, and mental exhaustion brought about by unrelieved stress is B) Burnout. Burnout is characterized by a trio of experiences: exhaustion, depersonalization, and diminished personal accomplishment. Exhaustion is when one feels that their emotional resources are depleted. Depersonalization refers to a detachment from the service one provides, often resulting in a cynical or indifferent attitude. Diminished personal accomplishment leads one to view their work negatively, with feelings of dissatisfaction or failure.
While stress can sometimes be positive and enhance performance (eustress), chronic or extreme stress, known as distress, can lead to burnout. Symptoms of burnout, like other stress responses, can be physiological, cognitive, and behavioral, and if unaddressed, may result in serious health issues, including depression, weakened immune response, and even heart disease.
