Answer Choices:
A perceived stressor stimulates the central nervous system.
● The first stage of the General Adaptation Syndrome (GAS) is the alarm stage, which begins when a stressor is perceived, triggering activation of the central nervous system (CNS).
● This leads to stimulation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system, initiating the body's immediate fight-or-flight response.
● Physiological changes follow this CNS activation, such as increased heart rate, blood pressure, and stress hormone release, preparing the body to respond to the threat.
● Recognizing that the CNS initiates the stress response helps nurses understand the progression of stress effects on the body and guides interventions that support stress regulation.
