52. Because the patient had a(n) *occluded* artery, the physician decided to perform cardiovascular surgery.
Answer: A
Obstructed
The term "occluded" refers to a blockage or obstruction in a blood vessel, which is precisely why the physician chose to perform cardiovascular surgery. This action is typically taken to restore proper blood flow.
A) Obstructed
This option is correct because "obstructed" directly correlates with the definition of "occluded." An occluded artery is one that is blocked, preventing normal blood circulation, which necessitates surgical intervention.
B) Open
This option is incorrect as "open" suggests that the artery is clear and unobstructed. If the artery were open, there would be no need for surgery, as blood would flow freely.
C) Broken
This option is not applicable because "broken" implies a physical fracture or separation, which is not synonymous with "occluded." An occluded artery may not be broken but rather blocked, making this choice incorrect.
D) Cloudy
This option is also incorrect. "Cloudy" does not relate to the physical state of an artery in the context of blockage. It typically refers to something being unclear or not transparent, which does not accurately describe an occluded artery.
Conclusion
The correct answer, "obstructed," accurately describes the condition of the artery that is occluded, leading to the necessity for surgical intervention. Other options fail to represent the medical condition appropriately, highlighting the importance of precise terminology in healthcare contexts.
