A friend was burned helping her mother cook dinner. The skin on her arm is red, swollen, and painful, with oozing blisters. What type of burn does she most likely have?

Redness, swelling, pain, and oozing blisters are typical signs of a second-degree burn, which damages the outer skin and the layer beneath it. A first-degree burn usually causes redness and pain without blisters, while a third-degree burn damages deeper tissue and may look white, charred, or leathery. The most likely answer is a second-degree burn.
