Review Question - QID 108441

A 10-year-old boy presents to the emergency department with a swollen and painful elbow after accidentally bumping his arm into the kitchen table. His mom notes that he seems to bruise and bleed easily, but this is the first time he has had a swollen joint. She also remembers that her uncle had a bleeding disorder, but cannot remember the diagnosis. Physical exam reveals a warm and tender elbow joint, but is otherwise unremarkable. Based on clinical suspicion, a bleeding panel is ordered with the following findings:

Bleeding time: 3 minutes
Prothrombin time (PT): 13 seconds
Partial thromboplastin time (PTT): 54 seconds

Which of the following treatments would most likely be effective in preventing further bleeding episodes for this patient?
