Removal of a client's peripheral intravenous catheter resulted in brief bleeding and the loss of a small amount of blood. Which of the following processes occurred during the formation of the platelet plug that helped to stop blood flow?

Question

A) Activation of factor X
B) Conversion of prothrombin to thrombin
C) Release of von Willebrand factor from the epithelium
D) Conversion of fibrinogen to fibrin threads

Answer 1

Ans: C
Feedback:
The release of von Willebrand factor from the epithelium contributes to platelet adhesion and the eventual formation of a platelet plug. Activation of factor X and the conversions of prothrombin to thrombin and fibrinogen to fibrin threads take place during the stage of blood coagulation.
