What is an additional symptom of a patient with this type of burn?

Hives are a skin reaction characterized by raised, itchy welts and are typically associated with allergic reactions or irritants rather than burns. Since hives do not occur as a result of thermal injury and are not a symptom of partial-thickness burns, this option is irrelevant in this context.

Pale skin is often associated with conditions like shock, poor circulation, or certain types of burns, such as full-thickness burns, where blood supply is severely compromised. In partial-thickness burns, the skin typically appears red and swollen rather than pale; therefore, this option does not accurately reflect the symptoms of such burns.

Charred skin is indicative of full-thickness burns, which destroy both the epidermis and dermis layers, resulting in a blackened, leathery appearance. Partial-thickness burns do not result in charring, as they only damage the upper layers of the skin; thus, this symptom is not applicable.
