Sample item

What is aspirin's antiplatelet mechanism?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Irreversible cyclooxygenase inhibition

The central Antiplatelet drugs concept identifies Irreversible cyclooxygenase inhibition as the best answer because it directly explains the mechanism, indication, adverse effect, or organism feature described.

Option by option

  • A. Fibrin breakdown

    Fibrin breakdown is unsupported by the mechanism or clinical clue in the stem.

  • B. Vitamin K antagonism

    Vitamin K antagonism does not fit the stated antiplatelet drugs relationship.

  • C. Irreversible cyclooxygenase inhibition (correct)

    Correct. Irreversible cyclooxygenase inhibition matches the decisive point in this scenario.

  • D. Direct thrombin activation

    Direct thrombin activation has another context but is not the most appropriate answer here.
