Question 1 of 5
A nurse is teaching a class about the stages of the general adaptive syndrome (GAS). The nurse should include that which of the following is the first physiological response that occurs during GAS?
Correct Answer: A
Rationale: The correct answer is A: A perceived stressor stimulates the central nervous system. This is the first physiological response in the General Adaptive Syndrome (GAS). When the body perceives a stressor, the hypothalamus in the brain triggers the release of stress hormones, such as cortisol and adrenaline, through the activation of the central nervous system. This initiates the fight-or-flight response, preparing the body to either confront or flee from the stressor. This initial response is crucial for the body to mobilize its resources and cope with the stressor effectively.
Incorrect choices:
B: The body remains alert while blood pressure and heart rate return to pre-stress levels - This statement does not accurately describe the initial physiological response during GAS.
C: Prolonged exposure to stress can result in illness - While true, this choice does not address the first physiological response in GAS.
D: An increase in hormones causes an increase in blood pressure and heart rate - While this is part of the body
