Final answer:
The nurse should plan the dosing time for Filgrastim (Neupogen) prior to the chemotherapy infusion to support the immune system.
Step-by-step explanation:
The nurse should plan the dosing time for Filgrastim (Neupogen) prior to the chemotherapy infusion. The purpose of Filgrastim is to stimulate the production of white blood cells, which can be suppressed after chemotherapy. By administering Filgrastim before chemotherapy, it allows time for the white blood cells to be produced and peak in number when the chemotherapy is administered. If the chemotherapy is scheduled for Thursday at 9 a.m., the nurse should plan to administer the Neupogen no later than 9 a.m. on Wednesday. Administering it immediately before or during the chemotherapy infusion is not recommended. Administering it immediately after chemotherapy can be considered in certain cases, but the best practice is to administer it prior to chemotherapy to support the immune system.
