A client with septic shock develops disseminated intravascular coagulation (DIC). Which pathophysiologic process should the nurse recognize as the cause of the coagulation problem?
Explanation & Rationale
Rationale A. The complement system is part of the immune response and can be activated in various conditions, including sepsis. However, activation of complement pathways does not directly cause DIC. Instead, in septic shock, the release of pro-inflammatory cytokines and tissue factor can trigger systemic coagulation activation, leading to DIC. B. Inhibition of red blood cell production, such as in conditions like aplastic anemia or certain types of bone marrow disorders, does not directly cause DIC. DIC is primarily a disorder of excessive activation of clotting factors in response to underlying conditions like sepsis, trauma, or cancer. C. Production of extra platelets, or thrombocytosis, is not the cause of DIC. Thrombocytosis can occur in response to various conditions, but DIC involves consumption of platelets due to widespread activation of clotting within the vasculature. D. DIC is characterized by the widespread consumption and depletion of clotting factors and platelets as they are used up in the formation of microthrombi throughout the bloodstream. This depletion leads to an increased risk of bleeding due to insufficient clotting factors remaining to maintain hemostasis.
