Deficient vitamin K absorption due to hepatic disease presents with which assessment finding?

Explanation:
Deficient vitamin K absorption in hepatic disease leads to a coagulation problem because vitamin K is needed to produce clotting factors II, VII, IX, and X. It is fat-soluble and requires bile for absorption, which is reduced in liver disease, so these clotting factors are decreased and the blood’s ability to clot is impaired. The result is a bleeding tendency evidenced by purpura and petechiae—small patches of bleeding under the skin from minor capillary injuries. Other options describe fluid buildup or hormonal changes seen with liver disease, not the specific coagulation defect caused by vitamin K deficiency.
