Hemostasis Quiz

Which of the following is the first stage of hemostasis?

• Platelet plug formation

• Vascular spasm

• Coagulation

• Fibrinolysis

What role do platelets play in hemostasis?

• They dissolve blood clots

• They form a temporary plug

• They convert fibrinogen to fibrin

• They release tissue factor

Which component stabilizes the clot during the final stage of hemostasis?

• Fibrin

• Thrombin

• Prothrombin

• Plasmin

The final stage of hemostasis, fibrinolysis, involves:

• Strengthening the clot

• Dissolving the clot

• Stopping blood flow

• Forming a platelet plug

Which of the following is a key enzyme in the coagulation phase of hemostasis?

• Thrombin

• Plasmin

• Collagen

• ADP

Vascular spasm is the final stage of hemostasis.

Platelets are involved in the formation of the initial plug during hemostasis.

Fibrinolysis involves the breakdown of the fibrin clot.

The coagulation phase strengthens the platelet plug with fibrin threads.

Hemostasis only involves the formation of blood clots.
