🔍 Key Concepts

• Cryogenic burns and frostbite are treated like cold injuries, not heat burns • Recommended water temperature range for re‑warming frostbitten tissue in standard first-aid guidance • Why rubbing, massaging, or using ice on frostbite can cause more damage

💭 Think About

• Think about whether a cryogenic burn makes the tissue very hot or very cold. How should a cold injury be treated at first? • What water temperature is considered safe for re-warming frozen tissue: cool, warm, very hot, or near-boiling? • Which options might further damage frozen tissue by causing ice crystals to tear cells or by overheating the skin?

✅ Before You Answer

• Eliminate any option that adds more cold (like ice) to already frozen tissue. • Eliminate any option that involves rubbing or massaging frostbitten areas. • Compare the given temperature to the commonly recommended lukewarm re‑warming range (typically around 99–104°F) and see which option is closest.
