KROK 1 2023 – Question 117 · KROK (Medicine) · Pathophysiology
A child with hemorrhagic syndrome was diagnosed with hemophilia B. What coagulation factor is deficient in this case, causing this type of hemophilia in the patient?
- A. VIII (antihemophilic globulin)
- B. II (prothrombin)
- C. IX (Christmas factor)
- D. XI (prothromboplastin)
- E. XII (Hageman factor)
Hint
Hemophilia A involves antihemophilic globulin; think about the different intrinsic-pathway factor that is deficient in the less common X-linked form, known by an eponym.
