In caring for an infant after circumcision, the nurse observes continued bleeding from the site and suspects hemophilia. Which hematological components are insufficient causing bleeding if hemophilia is present?

A) Deficiency of factors VIII or IX. Hemophilia is a genetic disorder characterized by deficient or defective clotting factors, specifically factors VIII (hemophilia A) or IX (hemophilia B). These clotting factors are essential for the formation of stable blood clots. Therefore, if hemophilia is present, the deficiency of factors VIII or IX can lead to impaired clot formation and prolonged bleeding. B) Diminished amount of vitamin K: Vitamin K deficiency can lead to impaired blood clotting due to inadequate synthesis of clotting factors in the liver. However, hemophilia is specifically associated with deficiencies in factors VIII or IX, not vitamin K. C) Decreased amount of platelets: Platelets play a crucial role in primary hemostasis and initial platelet plug formation at the site of vascular injury. While decreased platelet count or dysfunction can lead to bleeding disorders such as thrombocytopenia or platelet function disorders, hemophilia specifically involves deficiencies in clotting factors, not platelets. D) Missing factors V and VII: Factor V and VII are other clotting factors involved in the coagulation cascade, but they are not deficient in hemophilia. Hemophilia is specifically characterized by deficiencies in factors VIII (hemophilia A) or IX (hemophilia B).
