Her father also has similar issues. Physical exam reveals oral mucosal petechiae and bleeding at the site of tooth removal. Labs: normal platelet count. prolonged bleeding time, and normal PT. Platelet aggregation studies reveal lack of in vitro aggregation when Ristocetin is added. Which of the following is the most likely diagnosis? a) Aspirin ingestion b) Bernard-Soulier syndrome c) Glanzmann thrombasthenia d) Hemophilia B e) von Willebrand disease 2) A 14-year-old female complains of prolong bleeding during menses for the last 2 months. She and her brother tend to "bleed easily" with several nosebleeds. Physical exam demonstrates pallor, occasional petechiae on the skin and in the mouth.

Which of the following would the physician consider next? a) Call child protective services for concerns of physical abuse b) Order a platelet count to consider immune thrombocytopenic purpura c) Order prothrombin test (PT) to consider a clotting disorder d) Order assay for clotting factors VIII, IX, XI to consider hemophilia e) Treat with recombinant von Willebrand factor
