Blisters are a sign of which classification of burn? a. first-degree burn b. second-degree burn c. third-degree burn d. none of the above

Blisters are a sign of a partial thickness burn (which is the more correct wording of a Second degree burn). Superficial thickness burns (First Degree) are such things as sunburns, in which there is no real damage although the area is painful and usually red, this is due to the fact it just affects the epidermis. Partial-Thickness describes burns that go into the Dermis, and are exceptionally painful with blistering, peeling, and swelling. Full thickness burns are a wide coverage term for 3rd through 5th degree burns, where the burn has gotten into soft tissue like muscle and fat. Blistering, necrotizations, charred flesh, all up to the point of amputation describe these burns, however these burns are not directly painful because they have burned nervous tissue.

So your answer is Second Degree Burns.
