Which action indicates urgent transport for a suspected heat-related illness?

• A. Mild dizziness
• B. Heat cramps
• C. Headache resolving with rest
• D. Altered mental status

Answer: (D)

Altered mental status is the red flag in heat-related illnesses because it signals brain dysfunction from severe overheating, which can indicate heat stroke. When the CNS is involved, quick cooling and advanced care at a hospital are necessary, so urgent transport is required. Other symptoms like mild dizziness, heat cramps, or a headache that improves with rest can be managed with cooling, fluids, and rest and do not by themselves demand immediate transport. However, any confusion, disorientation, or altered consciousness means the situation may be life-threatening and needs rapid evacuation to a medical facility for aggressive cooling and monitoring.
