What term describes a small red or purple spot caused by bleeding into the skin?

• A. Petechia
• B. Pallor
• C. Induration
• D. Nodular

Answer: (A)

The term that describes a small red or purple spot caused by bleeding into the skin is petechia. These tiny spots appear when capillaries break and blood leaks into the surrounding tissue, often as a result of various conditions such as infections, trauma, or certain medical disorders that affect blood clotting or vascular integrity. Petechiae can be an important clinical sign indicating underlying health issues, and their presence is often evaluated in the context of a patient's overall condition.

Pallor refers to an unusual lightness of the skin color, usually indicating reduced blood flow or anemia, and does not describe any form of skin bleeding. Induration is the term used for hardening of soft tissue or skin, typically due to inflammation or the presence of a mass. Nodular describes a small, rounded mass or lump that can form in various tissues, but does not specifically relate to the bleeding or discoloration of the skin. Each of these terms conveys different aspects of skin and tissue conditions, but petechia specifically relates to the phenomenon of bleeding under the skin.
