A Nurse Is Teaching A Class About The General Adaptation Syndrome. The Nurse Should Include That Which Of The Following Manifestations Occurs During The Exhaustion Stage?A. Blood Pressure Increases.B. Blood Glucose Levels Return To The Expected
Introduction
The General Adaptation Syndrome (GAS) is a concept developed by Hans Selye, a renowned endocrinologist, to describe the body's response to stress. It is a three-stage process that involves the body's initial response to stress, followed by a period of adaptation, and finally, exhaustion. In this article, we will delve into the General Adaptation Syndrome, its stages, and the manifestations that occur during each stage.
What is the General Adaptation Syndrome?
The General Adaptation Syndrome is a physiological response to stress that involves the activation of the body's hypothalamic-pituitary-adrenal (HPA) axis. This axis is responsible for releasing hormones that help the body respond to stress. The HPA axis is activated when the body perceives a threat, and it triggers the release of hormones such as cortisol and adrenaline.
The Three Stages of the General Adaptation Syndrome
The General Adaptation Syndrome consists of three stages: alarm, resistance, and exhaustion.
Alarm Stage
The alarm stage is the initial response to stress. During this stage, the body's HPA axis is activated, and hormones such as cortisol and adrenaline are released. These hormones help the body respond to the stress by increasing heart rate, blood pressure, and respiration. The alarm stage is characterized by the body's "fight or flight" response, which prepares the body to either confront the stressor or flee from it.
Manifestations of the Alarm Stage
During the alarm stage, the body's manifestations include:
- Increased heart rate: The heart rate increases to pump more blood to the muscles, preparing the body for action.
- Increased blood pressure: Blood pressure increases to ensure that the brain and other vital organs receive adequate blood flow.
- Increased respiration: Respiration increases to provide the body with more oxygen.
- Increased glucose levels: Glucose levels increase to provide the body with energy.
- Increased cortisol levels: Cortisol levels increase to help the body respond to stress.
Resistance Stage
The resistance stage is the body's adaptation to stress. During this stage, the body's HPA axis continues to be activated, but the body begins to adapt to the stress by making changes to its physiological processes. The resistance stage is characterized by the body's ability to withstand the stressor for a longer period.
Manifestations of the Resistance Stage
During the resistance stage, the body's manifestations include:
- Increased muscle mass: Muscle mass increases to help the body respond to the stressor.
- Increased bone density: Bone density increases to help the body withstand the stressor.
- Increased immune function: Immune function increases to help the body fight off infections.
- Increased antioxidant levels: Antioxidant levels increase to help protect the body from oxidative stress.
Exhaustion Stage
The exhaustion stage is the final stage of the General Adaptation Syndrome. During this stage, the body's HPA axis is overactivated, and the body's physiological processes begin to break down. The exhaustion stage is characterized by the body's inability to withstand the stressor.
Manifestations of the Exhaustion Stage
During the exhaustion stage, the body's manifestations include:
- Decreased blood pressure: Blood pressure decreases due to the body's inability to maintain blood flow.
- Decreased glucose levels: Glucose levels decrease due to the body's inability to regulate blood sugar.
- Decreased cortisol levels: Cortisol levels decrease due to the body's inability to respond to stress.
- Increased risk of illness: The body's immune function is compromised, making it more susceptible to illness.
Conclusion
The General Adaptation Syndrome is a complex physiological response to stress that involves the activation of the body's HPA axis. The three stages of the General Adaptation Syndrome - alarm, resistance, and exhaustion - are characterized by different manifestations that occur as the body responds to stress. Understanding the General Adaptation Syndrome is essential for nurses and healthcare professionals to provide effective care to patients who are experiencing stress.

Introduction
The General Adaptation Syndrome (GAS) is a complex physiological response to stress that involves the activation of the body's hypothalamic-pituitary-adrenal (HPA) axis. In our previous article, we discussed the three stages of the General Adaptation Syndrome - alarm, resistance, and exhaustion - and the manifestations that occur during each stage. In this article, we will answer some frequently asked questions about the General Adaptation Syndrome.
Q: What is the General Adaptation Syndrome?
A: The General Adaptation Syndrome is a physiological response to stress that involves the activation of the body's HPA axis. It is a three-stage process that includes the alarm, resistance, and exhaustion stages.
Q: What is the alarm stage of the General Adaptation Syndrome?

- Increased blood pressure
- Increased respiration
- Increased glucose levels
- Increased cortisol levels
Q: What is the resistance stage of the General Adaptation Syndrome?
A: The resistance stage is the body's adaptation to stress. During this stage, the body's HPA axis continues to be activated, but the body begins to adapt to the stress by making changes to its physiological processes.
Q: What are the manifestations of the resistance stage?

- Increased muscle mass
- Increased bone density
- Increased immune function
- Increased antioxidant levels
Q: What is the exhaustion stage of the General Adaptation Syndrome?

Q: How can the General Adaptation Syndrome be prevented?
A: The General Adaptation Syndrome can be prevented by managing stress and engaging in activities that promote relaxation and reduce stress. This can include exercise, meditation, and deep breathing.
Q: What are the consequences of the General Adaptation Syndrome?
A: The consequences of the General Adaptation Syndrome can include:
- Decreased immune function
- Increased risk of illness
