What is characterized as a scrape or rub, typically affecting the knees or elbows?

An abrasion is a type of injury that occurs when the skin is scraped or rubbed away, often resulting from a surface-level scrape, which is common on areas like the knees or elbows during falls or accidents. This injury typically affects only the outer layer of skin, leading to pain, redness, and sometimes bleeding, but it generally heals without complications and does not involve deeper tissues. Identifying an abrasion correctly is important in the context of patient care, as appropriate treatment focuses on cleaning the area, preventing infection, and promoting healing. This understanding is crucial for medical assistants and healthcare providers when assessing and documenting patient injuries.
