Question 4Your work day today includes seeing new admits to a rehab center You see a 71 yo femalewith h o ITP s p prednisone in past She was recently given IVIG as an inpatient with goodresponse to her platelet count now about 50K PT and OT consulted and suggested rehabgiven ongoing steroid myopathy and general weakness from prior treatments When you.
see her at rehab she is icteric and Hgb is 5 and has dropped by 3 g dL in last 24 hours Platelets are about 40K and she has no active sign of bleeding You arrange for transportto ED with plans for transfusion but in ED she refuses a transfusion and is quitedisagreeable She says she is done with blood products The ED calls you saying theydon t see the point of admission and plan to let her discharge AMA unless rehab will take.
her back in this state You state that she should still be admitted You advise the ED to A Review the smear for shistocytes this now looks more like TTPB Send a G6PDC Call the blood bank and see if they carry Hemopure.
