Pivot Point Barbering 108 Practice Exam

Which of the following is an example of a primary lesion?

1. Scales

2. Pustules

3. Crusts

4. Fissures

The correct answer is: Pustules

Pustules are classified as primary lesions because they are raised, fluid-filled lesions that can indicate the presence of an infection or inflammation. They are typically filled with pus and represent a localized accumulation of fluid within the dermis or epidermis, resulting from various skin conditions such as acne or folliculitis. Pustules reflect an early stage of inflammation and are a primary response of the skin to irritation or infection. In contrast, scales, crusts, and fissures are considered secondary lesions. Scales result from the abnormal shedding of the stratum corneum, crusts form when dried serum, blood, or pus accumulates on the skin surface, and fissures are linear cracks in the skin. These secondary lesions indicate changes or developments that occur after the primary lesions have formed, often resulting from underlying skin issues. Understanding lesions is crucial for proper diagnosis and treatment in cosmetology and barbering practices.
