A nurse is assessing a client who has disseminated intravascular coagulation (DIC). Which of the following findings should the nurse expect?
Explanation & Rationale
Choice A rationale Disseminated intravascular coagulation (DIC) is characterized by widespread activation of the coagulation cascade, leading to the consumption of platelets and clotting factors, not an increase in platelet production. The body attempts to compensate, but consumption outpaces production, resulting in thrombocytopenia. Normal platelet count is 150,000 to 450,000 platelets per microliter. Choice B rationale DIC is pathologically defined by simultaneous excessive thrombosis and bleeding. Initial widespread microvascular clotting consumes platelets and coagulation factors, leading to tissue ischemia. Subsequent depletion of these crucial components results in paradoxical, severe bleeding from various sites, a hallmark of the disorder. Choice C rationale In DIC, clotting factors are consumed rapidly in the widespread microthrombotic process, leading to their significant decrease, not an increase. This depletion is a primary reason for the hemorrhagic manifestations seen in the later stages of the condition. Normal prothrombin time (PT) is 11-13.5 seconds, and activated partial thromboplastin time (aPTT) is 25-35 seconds. Choice D rationale Immediate sodium and fluid retention are not primary expected findings in DIC. While some fluid shifts can occur due to severe illness, the hallmark of DIC is a derangement of the coagulation system, not direct alterations in electrolyte balance or fluid volume regulation.
