🔍 Key Concepts

• Frostbite pathophysiology – what happens to tissue when it’s frozen and then handled roughly • Safe rewarming techniques – especially controlled, even heating vs. direct intense heat • Risks of walking or using a frostbitten limb during treatment

💭 Think About

• Which methods might cause additional tissue damage (crystals cutting cells, breaking fragile tissue, burns)? • Which option provides controlled, uniform warmth that can be accurately measured and kept in a safe range? • Think about what a first-aid manual or medical officer would recommend: is rewarming usually done with movement, friction, or with a controlled heat source?

✅ Before You Answer

• Eliminate any choice that could burn the skin or cause uneven overheating. • Eliminate any choice that involves rubbing or walking on frozen tissue, which can worsen damage. • Focus on the option that mentions a specific, moderate temperature range that can be monitored.
