Which of the following is a symptom associated with heatstroke?

Confusion or disorientation is a critical symptom associated with heatstroke, reflecting the severe effect that elevated body temperatures can have on the brain and overall cognitive function. Heatstroke occurs when the body's temperature regulation fails, leading to a rapid increase in core body temperature, often exceeding 104°F (40°C). This extreme heat can disrupt normal brain function, resulting in altered mental status, such as confusion, disorientation, or even loss of consciousness.

Other symptoms of heatstroke can include hot, dry skin, rapid pulse, and changes in behavior, but confusion is particularly significant as it can indicate a medical emergency that requires immediate intervention. The brain is especially vulnerable to high temperatures, making cognitive symptoms like confusion a clear sign that an individual may require urgent cooling and medical attention to prevent long-term damage or fatality.
