Classify the following statements and characteristics with the appropriate method of clotting prevention. Heparin interferes with the formation of prothrombin activator. Heparin promotes the action of antithrombin. Circulatory shock interferes with it. Normal rates of blood flow account for it. Antithrombin deactivates thrombin before it can act on fibrinogen. It occurs when blood vessels are undamaged. Heparin blocks the action of thrombin on fibrinogen. Prostacyclin coats the vessel walls. Repulsion Dilution Anticoagulants
