Question

question 25
the diagnostic term ar/rhythmia means:
○ obstruction of an artery in the heart
○ heart abnormality present at birth
○ vascular inflammatory disorder
○ variation in normal heart rhythm or contraction

question 26
what is coagulated or clotted material that develops inside the vascular system?
○ thrombus
○ infarction
○ atheroma
○ embolism

question 27
an embolism results from:
○ a detached thrombus
○ a stenosis
○ an occlusion
○ edema

Explanation:

• Question 25:
• The prefix "Ar" can relate to the heart (as in "arrhythmia" which is about heart rhythm). "Rhythmia" is related to rhythm. So, it's about heart rhythm.
• "Obstruction of an artery in the heart" would be more related to terms like "coronary artery blockage". "Heart abnormality present at birth" is a congenital heart defect. "Vascular inflammatory disorder" is about inflammation in blood vessels.
• Question 26:
• A thrombus is a blood clot formed inside a blood vessel.
• Infarction is tissue death due to lack of blood supply. Atheroma is a fatty deposit in artery walls. Embolism is when a clot (or other material) travels and blocks a vessel (but the question asks for the clot itself).
• Question 27:
• An embolism is often caused by a detached thrombus (which then travels and blocks a vessel).
• Stenosis is narrowing of a vessel. Occlusion is a blockage (but not specifically the cause of embolism). Edema is swelling.

Answer:

• Question 25: variation in normal heart rhythm or contraction
• Question 26: thrombus
• Question 27: a detached thrombus
