The nurse notes new areas of ecchymosis on the arms and legs of a client with liver cirrhosis. Which laboratory test results should the nurse monitor because of this finding? Select all that apply.

Rationale: A. While hepatitis can cause liver injury, antibodies do not provide information about current clotting ability or bleeding risk. They indicate past exposure or immunity, not active coagulopathy. B. Platelets are critical for primary hemostasis, and clients with liver cirrhosis often develop thrombocytopenia due to splenic sequestration or decreased production of thrombopoietin. Low platelet counts increase the risk of bruising and bleeding, which correlates with the observed ecchymoses. C. Elevated ammonia is associated with hepatic encephalopathy, not directly with bleeding or bruising. Monitoring ammonia is important for neurological status but not for coagulation. D. Liver cirrhosis impairs the synthesis of clotting factors, leading to prolonged PT, INR, and aPTT. Ecchymosis may indicate coagulopathy, so monitoring coagulation studies helps assess the severity of the bleeding risk. E. Albumin reflects synthetic liver function and nutritional status, but low albumin itself does not directly cause bruising. While hypoalbuminemia may indicate advanced liver disease, it does not provide immediate information about bleeding risk.
