Sample item

A boy with moderate haemophilia A needs an extraction. Which preparation reduces the risk of bleeding?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Factor VIII cover with tranexamic acid and local measures

Haemophilia A requires replacement of factor VIII, with antifibrinolytic tranexamic acid and local haemostatic measures. Desmopressin may be used in mild disease.

Option by option

  • A. Factor VIII cover with tranexamic acid and local measures (correct)

    Correct. Factor replacement with tranexamic acid controls bleeding.

  • B. Platelet transfusion

    Platelets are not deficient in haemophilia.

  • C. Vitamin K injection

    Vitamin K helps vitamin K dependent factors, not factor VIII.

  • D. Aspirin

    Aspirin impairs platelet function and increases bleeding.
