The nurse analyzes the laboratory results of a pediatric client with hemophilia. The nurse understands which result will most likely be abnormal in this client?

A. Hemophilia is a bleeding disorder that affects the clotting process, and the partial thromboplastin time (PTT) is typically prolonged in individuals with hemophilia, indicating a deficiency in clotting factors. B. Hemoglobin levels may remain normal unless the client experiences significant bleeding episodes. C. Platelet count is usually normal in hemophilia, as the disorder affects clotting factors rather than platelet production. D. Hematocrit levels may also remain normal unless there is significant bleeding, which would lower hematocrit due to blood loss.
