Question

why is it important to thin the blood of someone having a heart attack, but not for someone having a stroke?
a. strokes are not a cardiovascular disease and are not impacted by blood pressure.
b. thinning the blood will cause arteries to relax and allow blood to pass more easily.
c. for a stroke, it is necessary to control and stop the bleeding in the brain.
d. blood thinners are only useful for treating coronary heart disease.

please select the best answer from the choices provided.

○ a
○ b
○ c
○ d

Explanation:

• Option A: Strokes are cardiovascular diseases and blood pressure impacts them, so A is wrong.
• Option B: Blood thinning doesn't relax arteries; it reduces clotting, so B is incorrect.
• Option C: Some strokes (hemorrhagic) involve brain bleeding, so thinning blood would worsen it as we need to stop bleeding. This explains why we don't thin blood for such strokes.
• Option D: Blood thinners are used for other conditions too (e.g., some strokes), so D is wrong.

Answer:

C. For a stroke, it is necessary to control and stop the bleeding in the brain.
