A patient with idiopathic thrombocytopenic purpura (ITP) presents with heavy lochia and petechiae. As the nurse, which priority intervention would be most appropriate to prevent complications?

Rationale: A. Monitoring platelet levels is important for ongoing assessment, but it is not an immediate intervention to prevent bleeding complications. It informs treatment decisions but does not actively stop current bleeding. B. Vitamin K is primarily used to support clotting factor synthesis in liver disease or vitamin K deficiency. In ITP, the problem is immune-mediated destruction of platelets, not a vitamin K deficiency, so supplementation will not prevent bleeding. C. In patients with ITP who present with active bleeding, especially heavy lochia and petechiae, platelet transfusions are the priority intervention. They temporarily increase circulating platelet levels, helping to control bleeding and prevent serious complications such as hemorrhage. This intervention addresses the immediate risk to patient safety. D. Physical activity can increase the risk of trauma and bleeding in patients with low platelet counts. During active bleeding, activity should be limited, not encouraged.
