Answer 1

A bulla is the medical term for a large blister, typically defined as a fluid-filled lesion that is at least 5mm across.

Step-by-step explanation:

The medical term used to describe a large blister is a bulla. This term refers to a fluid-filled blister that is at least 5mm in diameter.

Conditions such as impetigo can result in the formation of bullae around areas like the nose and mouth.

Bullae are a type of lesion that can vary in size and may require medical attention if they become severe or are indicative of an underlying infection, such as in the case of necrotizing fasciitis.
