A localized collection of pus is called an?

• A. Bandage
• B. Abscess
• C. Infection
• D. Inflammation

Answer: (B)

The main concept tested is the term for a localized collection of pus. Pus is thick, often yellowish fluid made up of dead white blood cells, bacteria, and tissue debris. When an infection becomes confined to a specific spot, the body walls off the area and a pocket forms—an abscess. This distinguishes it from a general infection, which is the presence of pathogens anywhere in the body and may or may not involve a pus-filled pocket. Inflammation is the broader tissue response to injury or infection and can occur with or without pus. A bandage, by contrast, is just a dressing used to cover a wound, not the pocket of pus itself. So the best term for a localized pus collection is abscess.
