EMT Basic Certification Complete Practice Exam 2025

Question: 1 / 400

What occurs when a clot forms and blocks off circulation?

Embolism

Aneurysm

Thrombus

A clot that forms within a blood vessel, obstructing circulation, is referred to as a thrombus. This condition can develop in various scenarios, such as at the site of atherosclerosis or after blood vessel injury. When a thrombus forms, it restricts blood flow, potentially leading to tissue damage due to the lack of oxygen and nutrients, which is crucial for cellular function.

Understanding the context of the other terms helps clarify why they do not fit the definition provided in the question. An embolism involves a clot or debris that travels through the bloodstream and lodges in a vessel, while an aneurysm refers to a bulging or weakened area in an artery that can rupture, leading to bleeding. Shock is a life-threatening condition resulting from insufficient blood flow to meet the body's needs, which can be caused by various factors but does not specifically describe a clot blocking circulation.
