Which scenario would prompt initiating cooling measures during rehab?

• A. Normal core temperature with no symptoms.
• B. Elevated core temperature without any symptoms.
• C. Mild dehydration with no symptoms.
• D. Elevated core temperature with heat illness symptoms.

Answer: (D)

Cooling measures during rehab are started when the body shows signs of heat illness alongside an elevated core temperature. When someone has both a higher core temperature and symptoms such as dizziness, weakness, confusion, nausea, or headache, rapid cooling is needed to bring the temperature down quickly and prevent progression to heat stroke or other serious complications. If the temperature is elevated but there are no symptoms, or if there’s only mild dehydration with no symptoms, cooling isn’t immediately required; you would monitor, hydrate, and adjust activity as needed. The scenario with both elevated temperature and heat illness symptoms fits this need for active cooling best, because it reflects an unsafe, active heat-emergency state that requires intervention.
