Final answer:
In a toddler with hemophilia A, the expected laboratory values may include a prolonged activated partial thromboplastin time (aPTT) and decreased levels of factor VIII.
Step-by-step explanation:
In a toddler with hemophilia A, the expected laboratory values may vary depending on the severity of the condition. However, a common laboratory finding in hemophilia A is a prolonged activated partial thromboplastin time (aPTT), which measures the time it takes for blood to clot. The aPTT in a toddler with hemophilia A may be significantly prolonged compared to normal values. Other laboratory findings may include decreased levels of factor VIII, which is the clotting factor that is deficient in hemophilia A.
