Final answer:
After administering first aid, a first aider may transition from an alarm reaction to a stage of resistance, reflecting an adaptation to the stressor. In wound healing, following clot formation, the next response includes inflammation and white blood cell activity. Severe injuries may cause life-threatening reactions necessitating immediate medical attention.
Step-by-step explanation:
After first aid, the initial response known as the alarm reaction, characterized by high-stress levels and immediate physiological responses, diminishes as the body enters the stage of resistance. This adaptation mechanism allows the body to manage stress better though it still remains prepared for emergency actions. Following a skin injury, the body's wound-healing response begins with the formation of a blood clot.
The next response in the healing process typically includes inflammation and the arrival of white blood cells to fight infection and orchestrate tissue repair. In the case of severe injuries or stressors like anaphylactic shock, immediate medical intervention is crucial for survival as the body can react with life-threatening symptoms like respiratory distress, and plummeting blood pressure.
