Question

study plan for chapter 3: managing stress and coping with life’s challenges
part b - lo 2, explain key stress theories as well as the emotional, mental, and physiological changes that occur during the stress response
homeostasis a balanced physiological state in which all the body’s systems function smoothly. stress threatens homeostasis, and the body attempts to return to normal through adaptive response.
choose the statement below that correctly describes a phase of the general adaptation syndrome (gas)
the body runs out of energy to make adjustments to the stressor and resistance drops to normal levels during the exhaustion phase
the alarm phase of the gas triggers the flight-or-fight response, in which the body prepares to deal with a real or perceived threat.
during the alarm phase of the gas, epinephrine counteracts the effects of adrenaline.
during the resistance phase of the gas, the body resists the changes caused by the stressor and returns to homeostasis

Explanation:

1. Analyze the first option: In the exhaustion phase, the body's resistance drops below normal, not to normal levels, so this is incorrect.
2. Analyze the second option: The alarm phase of GAS does trigger the fight - or - flight response to prepare the body for a real or perceived threat. This matches the theory of GAS.
3. Analyze the third option: Epinephrine (adrenaline) and adrenaline are the same hormone (epinephrine is also called adrenaline), so one cannot counteract the other. This is incorrect.
4. Analyze the fourth option: In the resistance phase, the body tries to resist the stressor but may not return to homeostasis. Homeostasis is more likely to be restored in the recovery after the stressor is removed or in the alarm - resistance - exhaustion cycle's normal progression only if the stressor is short - lived. So this is incorrect.

Answer:

B. The alarm phase of the GAS triggers the flight - or - fight response, in which the body prepares to deal with a real or perceived threat.
