What is disseminated intravascular coagulation (DIC)?

What is disseminated intravascular coagulation (DIC)?

• A. A mild clotting disorder.
• B. A condition causing widespread activation of the clotting process.
• C. A situation resulting in high vitamin K levels.
• D. An isolated incident of thrombocytopenia.

Answer: (B)

Disseminated intravascular coagulation (DIC) is characterized by widespread activation of the clotting process within the blood vessels. This condition leads to the formation of small blood clots throughout the vascular system, which can consume clotting factors and platelets, resulting in a paradoxical increased risk of bleeding despite the presence of clots. DIC can be triggered by various underlying conditions, such as severe infections, trauma, or obstetric complications, and often presents as a serious, life-threatening emergency that requires immediate medical intervention. The other options do not accurately represent DIC. It is not simply a mild clotting disorder; rather, it is a complex coagulopathy with significant clinical implications. Similarly, while vitamin K is essential for proper clotting factor synthesis, DIC is not directly related to elevated vitamin K levels. Furthermore, thrombocytopenia in DIC is not isolated; it is part of a broader spectrum of coagulopathic changes resulting from widespread clotting and consumption of platelets. Thus, the correct description of DIC focuses on its nature as a condition causing active and widespread clotting abnormalities throughout the body.
