Sample Answer
Systems Affected:
Circulatory:
- Reduced plasma volume
- Increased blood viscosity
- Compromised cardiac output
Muscular:
- Reduced oxygen delivery
- Electrolyte imbalance
- Increased risk of cramping
Thermoregulatory:
- Decreased sweating efficiency
- Reduced cooling capacity
- Elevated core temperature
Nervous:
- Altered coordination
- Reduced concentration
- Potential confusion
First Aid Management:
Immediate Response:
- Activity cessation
- Vital sign assessment
- Core temperature monitoring
- Conscious state check
Treatment Protocol:
- Controlled rehydration strategy
- Electrolyte replacement
- Cooling measures if needed
- Regular reassessment
- Emergency services for severe cases
Prevention Strategies:
- Pre-event hydration protocols
- Regular fluid intake monitoring
- Early intervention when symptoms present
- Education about system responses
