What is a common characteristic of abrasions?

• A. They penetrate through all skin layers
• B. They are usually caused by friction against a rough surface
• C. They are associated with broken bones
• D. They always require medical intervention

Answer: (B)

Abrasions are defined as superficial injuries to the skin that occur when the skin rubs or scrapes against a rough surface. This type of injury typically impacts only the outermost layer of the skin, known as the epidermis, and may not usually penetrate deeper into the layers of skin. The mechanism of injury often involves friction, which is why option B is correct. The other options do not align with the nature of abrasions. For example, abrasions do not penetrate through all skin layers, so that option describes a different kind of injury, like a laceration or an incised wound. Similarly, abrasions are not inherently associated with broken bones; they can occur independently, typically without any bony involvement. Lastly, while some abrasions might require medical intervention depending on their severity or the risk of infection, most minor abrasions can be adequately treated with simple first aid measures, meaning they do not always require professional medical treatment.
