Which term describes a stationary clump of platelets?

• A. Thrombus
• B. Embolism
• C. Aneurysm
• D. Intermittent claudication

Answer: (A)

A stationary clot that forms in a vessel is called a thrombus. It forms in place and remains attached to the vessel wall, often composed of platelets and fibrin in arterial clots. If such a clot stays put, it’s a thrombus; if it breaks off and travels through the bloodstream, it becomes an embolus. The other options describe different ideas: an aneurysm is a dilation of a vessel, and intermittent claudication is pain from insufficient blood flow, while an embolism is a traveling piece that can lodge elsewhere. So the term for a stationary clump of platelets is thrombus.
