What is the primary pathophysiological process that occurs in disseminated intravascular coagulation (DIC)?
Decreased production of clotting factors
Impaired platelet function
Excessive activation of clotting factors and widespread clot formation
Excessive platelet production
The Correct Answer is C
A. DIC is not characterized by decreased production of clotting factors. Instead, it involves consumption of clotting factors due to widespread activation of coagulation.
B. While platelet dysfunction may occur in DIC due to consumption and depletion of platelets, the primary pathophysiological process in DIC is the activation of clotting factors and formation of blood clots throughout the vasculature.
C. Excessive activation of clotting factors and widespread clot formation is the primary pathophysiological process in DIC. This leads to the formation of numerous small blood clots throughout the body's blood vessels, resulting in organ dysfunction and potentially life-threatening complications.
D. Excessive platelet production is not a characteristic feature of DIC. Instead, platelets are consumed and depleted as they are incorporated into the blood clots formed during the
coagulation cascade in DIC.
