In field assessment, which finding most supports heat-related illness rather than trauma?

• A. History of exposure with dry hot skin and CNS symptoms
• B. Visible blunt trauma and deformities
• C. Hyperthermia with CNS symptoms, history of exposure, and dry hot skin
• D. Normal skin temperature with localized swelling

Answer: (C)

Focus on signs that point to heat-related illness rather than injury from trauma. The strongest clue is hyperthermia, meaning an elevated body temperature, paired with central nervous system changes (such as confusion, agitation, or altered mental status) and a history of exposure to a hot environment. Dry, hot skin supports heat illness when sweating has failed, which is a classic presentation of heat stroke. In contrast, trauma typically shows evidence of injury like visible blunt trauma, deformities, or localized swelling rather than a primary heat problem. So the combination of high body temperature with CNS symptoms and a heat exposure history best supports heat-related illness, making the option with hyperthermia plus CNS signs, exposure history, and dry skin the most accurate finding.
