Which of the following categorizes lesions into primary, secondary, and tertiary types?

The correct choice categorizes lesions into primary, secondary, and tertiary types, directly reflecting how dermatologists and skin care professionals organize skin lesions based on their characteristics and development.

Primary lesions are the initial changes in the skin that occur due to a disease process, such as macules or papules. Secondary lesions arise from changes to primary lesions, including crusts or scales. Tertiary lesions are associated with systemic diseases and are less common, often resulting from persistent or chronic inflammation. This classification system helps professionals identify and understand the nature of skin conditions, allowing for accurate diagnosis and treatment.

In contrast, signs of infection focus on indicators like redness, swelling, or pus that signify an infectious process rather than providing a categorization system for lesions. Dermatological conditions encompass a broader spectrum of skin issues and may include various types of lesions but do not specifically categorize them. Lastly, types of nail disorders are related specifically to nail health and conditions, which is a different area of focus than skin lesions.
