Final answer:
The sympathetic fight-or-flight response is a natural response of the body to perceived danger or stress. Some physiological changes occur during this response, but severe thirst is not one of them.
Step-by-step explanation:
Answer:
The sympathetic fight-or-flight response is a natural response of the body to perceived danger or stress. It prepares the body to either confront the threat or escape from it. Some common physiological changes that occur during the fight-or-flight response include:
- Increased heart rate: The heart beats faster to pump more oxygenated blood to the muscles and vital organs.
- Difficulty breathing: Breathing becomes faster and more shallow to increase the oxygen intake.
- Sweating: Increased sweating helps cool down the body and prevent overheating during physical exertion.
- Severe thirst: This is not considered an immediate indicator of critical incident stress and is not a characteristic of the fight-or-flight response.
Therefore, the correct answer is D. Severe thirst.
