23. What does the word "occluded" mean in the sentence below? "Due to an occluded artery, the physician decided to perform cardiovascular surgery."
Answer: A
Obstructed
In the context of the sentence, "occluded" refers to an artery that is blocked or obstructed, necessitating cardiovascular surgery. This is a medical term commonly used to describe a blockage in blood vessels.
A) Obstructed
This option is correct because "occluded" literally means blocked or obstructed, particularly in a medical context where it describes arteries that are not allowing blood to flow through due to blockage.
B) Open
This option is incorrect as "open" indicates a lack of obstruction. An "open" artery would not require surgical intervention, making this definition incompatible with the context of the sentence.
C) Broken
This choice is also incorrect. While an occluded artery may be damaged, the term "broken" does not accurately capture the meaning of "occluded," which specifically refers to blockage rather than physical breakage.
D) Cloudy
This option is incorrect as well since "cloudy" describes a lack of clarity or transparency and does not relate to the condition of an artery in a medical sense. "Occluded" pertains to blockage, not clarity.
Conclusion
The term "occluded" clearly conveys the idea of an artery being obstructed, which aligns perfectly with option A. The other options fail to capture the specific medical implication of the term, reinforcing why A is the only suitable choice in this context.
