While receiving a type compatible platelet, the patient started having urticarial rash
around the transfusion site. The nurse stopped the transfusion, medicated the patient
with antihistamine, and then continued transfusing the remaining product. The
transfusion reaction was reported after completion of the product.
If an urticarial rash is the only symptom, treating the symptom and continuing to
transfuse is acceptable
The nurse is going against FDA protocol by continuing transfusion
If another symptom was present, this still would have been the correct route of action -
