The nurse suspects a client with disseminated intravascular coagulation (DIC) secondary to sepsis is experiencing microthrombi. Which finding indicates organ ischemia caused by microvascular thrombi?
Explanation & Rationale
Rationale: A. Hematuria, or blood in the urine, results from bleeding in the urinary tract due to depletion of platelets and clotting factors. It reflects the hemorrhagic aspect of DIC rather than ischemia from microvascular thrombi. B. Petechiae are small, pinpoint, reddish-purple spots on the skin caused by capillary bleeding due to thrombocytopenia. They are a hallmark of bleeding in DIC, not of tissue ischemia caused by microthrombi. C. Anuria, defined as urine output less than 50 mL in 24 hours, indicates renal ischemia caused by microvascular thrombi blocking the renal microcirculation. In DIC, the kidneys are highly susceptible to microthrombi formation because of their dense microvascular network, leading to decreased perfusion, acute kidney injury, and potential renal failure. This finding is a direct indicator of organ ischemia rather than a bleeding manifestation. D. Oozing or prolonged bleeding from IV sites is a sign of impaired hemostasis caused by platelet and clotting factor depletion. While it reflects the consumptive bleeding process of DIC, it does not indicate microvascular obstruction or organ ischemia.
