CLO4 HML3003

Which vitamin is essential for the synthesis of clotting factors II, VII, IX, and X?

• Vitamin A

• Vitamin K

• Vitamin D

• Vitamin B12

Which of the following is NOT a cause of vitamin K deficiency?

• Dietary deficiency

• Poor absorption

• Excessive platelet production

• Liver disease

What is the primary role of vitamin K in hemostasis?

• Completing the synthesis of clotting factors

• Breaking down fibrin clots

• Increasing red blood cell production

• Inhibiting coagulation

Which laboratory finding is associated with vitamin K deficiency?

• Increased platelet count

• Prolonged PT & APTT

• Decreased fibrinogen levels

• Increased D-dimer

Disseminated Intravascular Coagulation (DIC) is characterized by:

• Localized clot formation

• Systemic fibrin formation in all blood vessels

• Excessive platelet production

• Increased fibrinogen levels

Which of the following is a common cause of DIC?

• Hypertension

• Sepsis

• Vitamin D deficiency

• Iron deficiency

In chronic DIC, the consumption and production of clotting factors are:

• Unequal, leading to severe thrombosis

• Nearly balanced

• Rapidly depleted

• Normal

Which test helps differentiate DIC from primary fibrinolysis?

• PT and APTT

• D-dimer assay

• Platelet count

• Blood glucose level

Which of the following laboratory findings is expected in acute DIC?

• Low platelet count

• Normal PT and APTT

• Increased fibrinogen

• Decreased FDPs

What is the primary treatment approach for DIC?

• Ignore the primary cause

• Treat the underlying condition

• Administer anticoagulants at high doses

• Increase platelet transfusions only
