When evaluating Chris's situation after football practice, which symptom highlights a potential fluid imbalance?

In evaluating Chris's situation, the symptom that highlights a potential fluid imbalance is elevated body temperature. When an individual is dehydrated or has an imbalance of fluids, their body may struggle to regulate temperature effectively. During physical exertion, such as football practice, proper hydration is crucial for thermoregulation.

If the body cannot cool itself effectively due to a lack of fluids, it may result in heat-related issues, causing an elevation in body temperature. This is particularly critical in sports, where high temperatures can lead to more serious conditions like heat exhaustion or heat stroke.

On the other hand, bruising on the arms may indicate other concerns, such as potential injuries or issues related to blood clotting but does not directly indicate a fluid imbalance. High cholesterol is more related to dietary habits and metabolic health rather than fluid status. Effective hydration, by contrast, suggests that there is no issue with fluid balance.
