Question

Quizplus · Accepted Answer

Platelet aggregation occurs first in hemostasis, as it is the initial response to injury to form a temporary plug to prevent further bleeding.

The other options occur later in the hemostatic process:
A) Activation of the fibrinolytic system occurs later to dissolve the clot once healing has occurred.
C) A clotting cascade that leads to the conversion of fibrinogen to stable fibrin occurs after platelet aggregation to form a stable clot.
D) Conversion of prothrombin to thrombin occurs as part of the clotting cascade and results in the conversion of fibrinogen to fibrin.
E) Conversion of plasminogen to plasmin occurs as part of the fibrinolytic system and is important for dissolving the clot.
