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?
A perceived stressor stimulates the central nervous system.
The body remains alert, while blood pressure and heart rate return to pre-stress levels.
Prolonged exposure to stress can result in illness.
An increase in hormones causes an increase in blood pressure and heart rate.
The Correct Answer is A
Choice A rationale
The first physiological response that occurs during the General Adaptation Syndrome (GAS) is
the alarm reaction stage. This stage is the body’s initial response to stress, where the sympathetic nervous system is activated by the sudden release of hormones.
Choice B rationale
The body remaining alert while blood pressure and heart rate return to pre-stress levels is part of the resistance stage of GAS, not the first physiological response.
Choice C rationale
Prolonged exposure to stress resulting in illness is associated with the exhaustion stage of GAS, which is the final stage, not the first physiological response.
Choice D rationale
An increase in hormones causing an increase in blood pressure and heart rate is part of the alarm reaction stage, but it is not the first physiological response. The first response is the perception of a stressor that stimulates the central nervous system.

Correct Answer is C
Explanation
Choice A rationale
While the thickness of the tympanic membranes can indeed change with age, it typically increases rather than decreases. Thickening of the tympanic membranes can contribute to hearing loss by reducing the ability of the ear to transmit sound vibrations.
Choice B rationale
Tinnitus, or ringing in the ears, is not typically decreased in older adults. In fact, tinnitus is often more common in older individuals and can be a sign of age-related hearing loss.
Choice C rationale
A decreased ability to hear high-frequency sounds is a common physiological change associated with aging. This is often one of the first signs of age-related hearing loss.
Choice D rationale
Decreased ear wax is not typically associated with aging. In fact, some older adults may produce more ear wax, which can contribute to hearing problems if it becomes impacted.
