Which of the following is an example of the alarm reaction stage of the general adaptation syndrome?

• A. A person develops chronic fatigue and a weakened immune system after prolonged exposure to stress.
• B. A person gradually adapts to ongoing stress and maintains normal functioning despite continued pressure.

Answer: (D)

Verified step by step guidance

1. Understand that the General Adaptation Syndrome (GAS) describes the body's short-term and long-term reactions to stress, consisting of three stages: alarm reaction, resistance, and exhaustion.
2. Identify the alarm reaction stage as the initial response to a stressor, characterized by immediate physiological changes such as activation of the sympathetic nervous system.
3. Recognize key physiological signs of the alarm reaction stage, including increased heart rate, release of adrenaline, and heightened alertness.
4. Compare each option to these characteristics: the option describing rapid heartbeat and increased adrenaline fits the alarm reaction stage because it reflects the body's immediate response to stress.
5. Conclude that the example involving rapid heartbeat and increased adrenaline after a loud noise exemplifies the alarm reaction stage, while other options correspond to later stages or recovery.
