Final answer:
A temperature above 40°C, an altered mental status, and rhabdomyolysis in a young individual working in a boiler room suggest exertional heat stroke.
Step-by-step explanation:
A temperature above 40°C, an altered mental status, and rhabdomyolysis (greatly elevated creatine kinase with myoglobinuria and acute kidney injury) in a young, otherwise healthy individual who has been working in a boiler room is suggestive of exertional heat stroke.
Exertional heat stroke is a life-threatening condition that occurs when the body's temperature regulation mechanisms fail to keep the body cool during strenuous physical activity or exposure to hot environments. It can lead to severe organ damage and even death.
Exertional heat stroke requires immediate medical attention and treatment to cool the body temperature and prevent further complications.
