A frost bite patient is rewarmed at what temperature? 
Select and explain. 
A. 37? C, B. 42? C, C. 44? C, D. 46? C
A: 37? C
Answer: A: 37? C 
Explanation: Gently rewarm frostbitten areas. Soak the frostbitten areas in warm water -- 99 to 104 degree F (37? to 40 ?). If a thermometer isn't available, test the water by placing an uninjured hand or elbow in it -- it should feel very warm -- not hot. Rewarming takes about 30 minutes. Stop the soaking when the skin becomes its normal colour or loses its numbness
