Final answer:
C. Thrombocytopenia. A prolonged prothrombin time or partial thromboplastin time would indicate a problem with secondary hemostasis such as thrombocytopenia or thrombocytopathy. Thrombocytopenia is a condition characterized by an insufficient number of platelets leading to excessive bleeding. Thrombocytopathy refers to a dysfunction of platelets affecting their ability to clot properly.
Step-by-step explanation:
A prolonged prothrombin time or partial thromboplastin time would indicate a problem with secondary hemostasis such as thrombocytopenia or thrombocytopathy. Thrombocytopenia is a condition characterized by an insufficient number of platelets, leading to the inability of blood to form clots, resulting in excessive bleeding. On the other hand, thrombocytopathy refers to a condition where there is a dysfunction of platelets, affecting their ability to clot properly.
In contrast, Von Willebrand's disease is a congenital bleeding disorder characterized by a deficiency or dysfunction of von Willebrand factor, a protein that plays a role in clotting. Rodenticide poisoning, on the other hand, can interfere with the clotting process by inhibiting the synthesis of vitamin K, which is necessary for the production of clotting factors in the liver.
