Question

1. an embolism results from:

a detached thrombus
a stenosis
an occlusion
edema

1. a patient may display an ecchymosis after a/an:

arrhythmia
cerebral thrombosis
motor vehicle accident
myocardial infarction

Explanation:

Question 70

An embolism is a blockage in a blood vessel caused by a substance (like a blood clot) that travels from another part of the body. A detached thrombus (blood clot) can travel and cause an embolism. Stenosis is narrowing of a vessel, occlusion is a blockage (but not from a detached clot), and edema is fluid accumulation, none of which directly cause an embolism like a detached thrombus.

Ecchymosis is a bruise (discoloration from blood under the skin). A motor vehicle accident can cause trauma leading to bruising. Arrhythmia is a heart rhythm issue, cerebral thrombosis is a brain blood clot, and myocardial infarction is a heart attack—these don't typically cause ecchymosis as directly as trauma from an accident.

Answer:

a detached thrombus
