American EMT Academy Week III Practice Test

Urticaria is the medical term for which skin condition?

burning. swelling. hives. a wheal.

Correct Answer:

hives.

Explanation:

Urticaria describes the condition known commonly as hives. It refers to the appearance of itchy, raised welts on the skin. Each bump is a wheal, formed by edema in the superficial dermis due to histamine release from mast cells. The overall, recognizable skin condition that corresponds to urticaria is hives, not just a single lesion. The other terms don’t name the condition: burning is a sensation associated with burns or dermatitis, swelling alone is a generic description of edema, and a wheal is the individual lesion rather than the name of the condition.
