    Platelet count < 30 —– STEROID….
    < 30 & no response to steroid in acute setting, or pt. needs surgery —– GIVE IVIG
    < 30 for 3 months with steroid OR < 10 for 4-6wks with steroid ——SPLENECTOMY

    <15 OR < 50 with Intracranial hemorrhage/or life threatening bleeding —————- PLATELET TRANSFUSION

  3. Answer C)
    Master the board
    Platelet count > 50,000 – no treatment
    count <50,000 with minor bleeding – prednisone
    count <20,000 with serious bleeding – IVIG or Rhogam
    Recurrent episodes – splenectomy
