Question

Quizplus · Accepted Answer

Aspirin inhibits the synthesis of prostaglandins, which are involved in the activation of platelets and formation of the platelet plug. Thus, inhibiting their synthesis would prevent clot formation. Choices A, B, and C would all increase platelet activation and clot formation, so they are not correct.
