Care Manager Certification Practice Exam

What is the first physiological response that occurs during the general adaptive syndrome (GAS)?

1. Prolonged exposure to stress can result in illness.

2. The body remains alert, while blood pressure and heart rate return to prestress levels.

3. A perceived stressor stimulates the central nervous system.

4. An increase in hormones causes an increase in blood pressure and heart rate.

The correct answer is: A perceived stressor stimulates the central nervous system.

The first physiological response during the general adaptive syndrome (GAS) involves the body's reaction to a perceived stressor, which stimulates the central nervous system (CNS). This stimulation is crucial as it sets the stage for the body's overall stress response. When a stressor is perceived, the CNS activates the hypothalamus, which subsequently triggers the release of stress hormones, including adrenaline and cortisol, leading to a series of physiological changes. This initial reaction is essential because it prepares the body to respond to the stressor, often referred to as the "fight or flight" response. Blood pressure and heart rate begin to increase in this phase, as the body gears up to cope with the perceived threat. Understanding this initial response is important for care managers, as they can better recognize how stress impacts physical health and what interventions may be necessary to support individuals facing stressors. The other answer choices address different aspects of the general adaptive syndrome or consequences of prolonged stress but do not capture the immediate physiological reaction to a stressor, which begins with CNS activation.
