What are petechiae?

• A. Large bruises on the skin
• B. Tiny, raised bumps on the skin
• C. Tiny, non-raised red spots on the skin
• D. Swollen areas on the skin due to allergic reactions

Answer: (C)

Petechiae are tiny, non-raised red spots on the skin that result from bleeding underneath the skin's surface. These spots typically appear as small dots and are often caused by a variety of factors, including minor trauma, certain medical conditions, or problems with blood clotting. While they can indicate issues that may require medical evaluation, petechiae are differentiated from other forms of skin discoloration, such as large bruises or allergic reactions, which manifest differently. Understanding this helps in identifying potential underlying health concerns, making it crucial for healthcare professionals, including those in phlebotomy, to recognize these signs accurately.
