A small inflamed elevation filled with bacterial fluid and pus, appearing red and cloudy or white, is known as a:

1. Macule

2. Pustule

3. Vesicle

4. Furuncle

The correct answer is: Pustule

A small inflamed elevation that is filled with bacterial fluid and pus, which appears red and cloudy or white, is identified as a pustule. Pustules are a common form of acne and other skin issues, characterized by their visible pustular tissue, often indicating an infection or inflammatory response in the skin. This type of lesion typically arises from the skin's immune response to bacteria, leading to localized inflammation and the accumulation of pus. This pus consists of dead white blood cells, bacteria, and cellular debris, giving the pustule its distinct appearance. In contrast, macules are flat, discolored spots on the skin without elevation or associated swelling, while vesicles are small blisters containing clear fluid. Furuncles, commonly known as boils, are deeper abscess formations that occur in hair follicles and are typically larger and more painful than pustules. Thus, the distinctive combination of being elevated, filled with pus, and the characteristic appearance of redness makes the pustule the correct answer.
