Which term describes a moving clump of platelets?

• A. Shocking the heart to restart it
• B. A moving clump of platelets
• C. A stationary clump of platelets
• D. Difficulty breathing while lying down

Answer: (B)

A moving clot in the bloodstream is called an embolus. When a clot forms in one spot and then breaks free and travels, it becomes an embolus that can lodge in vessels elsewhere. A clot that stays in place is a thrombus, a stationary mass. So the term for a moving clump of platelets is embolus. This distinction matters because emboli can travel and block vessels in critical areas, like the lungs, brain, or heart. The other phrases refer to different concepts: defibrillation is shocking the heart to restart it, a stationary clot is a thrombus, and orthopnea means difficulty breathing when lying down.
