Which of the following clinical findings would you expect in your patient with disseminated intravascular coagulation (DIC)?

Choice A rationale Hypertension is not a typical finding in disseminated intravascular coagulation because the pathology involves systemic microvascular thrombosis and subsequent consumption of clotting factors. This process leads to severe bleeding and often results in hypovolemia or systemic inflammatory response syndrome. These conditions generally cause hypotension rather than elevated blood pressure. Blood pressure monitoring is crucial as a decline often signals worsening clinical status or the onset of hemorrhagic shock. Choice B rationale Dependent edema is usually associated with heart failure, renal failure, or low oncotic pressure from protein loss. While patients with this coagulopathy can develop generalized edema due to capillary leak or organ failure, it is not a primary diagnostic hallmark of the clotting disorder itself. The focus in disseminated intravascular coagulation is on the paradox of widespread clotting and bleeding rather than the localized fluid accumulation seen in venous insufficiency. Choice C rationale While microthrombi can technically impair local blood flow, decreased peripheral pulses are more indicative of obstructive shock, severe dehydration, or peripheral arterial disease. In this hematologic emergency, the systemic depletion of fibrinogen and platelets leads to a high risk of hemorrhage. Pulses may become weak if the patient becomes hemodynamically unstable from blood loss, but this is a secondary effect of shock rather than a specific finding of the coagulopathy. Choice D rationale Petechiae and purpura are classic manifestations because the condition involves the rapid consumption of platelets and clotting factors, a process known as consumption coagulopathy. Normal platelet counts are 150,000 to 400,000 cells/mm, but in this state, they drop significantly. Small capillary bleeds manifest as pinpoint red spots or larger purple patches on the skin. This indicates that the primary homeostatic mechanism has failed and the patient is at extreme risk for internal bleeding.
