Final answer:
In Hemophilia A, the nurse would anticipate a deficiency of clotting factor VIII, as this genetic disorder results in inadequate production of this specific clotting factor.
Step-by-step explanation:
The condition in question, Hemophilia A, is characterized by the inadequate production of clotting factors, specifically a deficiency in clotting factor VIII. This genetic disorder is part of a group of disorders that affect the body’s blood clotting capabilities. In the scenario presented, a nurse assessing a 12-year-old with Hemophilia A would anticipate a deficiency of clotting factor VIII, which is crucial for the blood clotting process.
