what is a characteristic of third - degree burns?
a.) they heal within a few days without medical attention.
b.) they destroy all nerve endings and sensory function.
c.) they are typically very painful.
d.) they only affect the epidermis.

Explanation:

Third - degree burns are severe. They damage all layers of the skin (not just the epidermis as in option d). First - degree burns (which only affect the epidermis) can heal in a few days without medical attention (so option a is wrong). Third - degree burns destroy nerve endings. Since pain is sensed by nerve endings, third - degree burns are not typically very painful (contradicting option c).

Answer:

B. They destroy all nerve endings and sensory function.
