PLE-5717

A 74-year-old woman, who is undergoing chemotherapy for advanced lung cancer, presents to the infusion center for her next treatment. Before each treatment, her white count, hemoglobin, and platelet counts are checked to make sure she is not experiencing chemotherapy-related cytotoxicity. Her blood sample is run in the analyzer, and her platelet count is reported to be at a dangerously low level. Which medication is her oncologist likely to prescribe in this situation, along with a platelet transfusion?
