Answer to Question 1

C
Frostbite is categorized by degree of injury, much like burns. Second-degree injury is characte-rized by redness, swelling, and formation of blisters filled with clear or milky fluid that forms within 24 hours of injury. A first-degree injury includes reddened skin, swelling, waxy appear-ance, hard white plaques, and sensory deficit. Third-degree injury consists of blood-filled blisters followed by black eschar forming over several weeks. Fourth-degree injury involves full-thickness damage affecting muscles, tendons, and bone, resulting in tissue loss.

Answer to Question 2

C
Lactic acid in the blood that was pooled in the extremities while being exposed to cold will shunt back to the heart through systemic perfusion as the warming process becomes effective. The lac-tic acid can cause arrhythmias.
