Problem: A 16 year old female is in the emergency room after being hit by a car. She has a history of a tonsillectomy at the age of 12 with no transfusions needed at that time. She has no previous history of an antibody. Pretransfusion Testing Results: ABO/Rh: B negative Antibody Screen: negative. Looking for Assignment Help? 1. What type of crossmatch would be suitable for this patient? 2. What units would be compatible? 3. The doctor has ordered a unit of platelets. Current inventory is 1 unit of O positive platelet and 2 units of B positive platelets. Do we need to order a platelet for the patient or can current inventory be used?
