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 A
Explanation
Choice A rationale
Allowing extra time to communicate with the patient is a crucial action when caring for a patient with impaired speech. This approach respects the patient’s autonomy and ensures that they have the time they need to express themselves.
Choice B rationale
Finishing sentences for the patient can be seen as disrespectful and may lead to frustration. It’s important to allow the patient to communicate at their own pace.
Choice C rationale
While open-ended questions can be useful in some situations, they may be challenging for a patient with impaired speech. It might be more effective to ask yes/no questions or use other communication aids.
Choice D rationale
Visual aids can be very helpful for patients with speech impairments. They can supplement verbal communication and make it easier for the patient to understand and be understood.
Correct Answer is B
Explanation
Choice A rationale
Hypoglycemia, or low blood sugar, is not typically a manifestation of the fight-or-flight response. In fact, the opposite is true. During the fight-or-flight response, the body’s glucose levels often increase to provide extra energy for the perceived threat.
Choice B rationale
Dilated pupils are a common physical manifestation of the fight-or-flight response. This physiological change allows more light to enter the eyes, enhancing vision and awareness of the environment during a stressful event.
Choice C rationale
Bronchial airway constriction is not typically associated with the fight-or-flight response. In fact, the bronchial airways often dilate during this response to allow for increased oxygen flow, which is necessary for physical exertion.
Choice D rationale
Decreased blood pressure is not a typical response to stress. During the fight-or-flight response, blood pressure usually increases to enhance blood flow to the muscles and brain.
