After administering five doses of filgrastim, the nurse observes that the patient’s white blood cell count has increased from 2,500/mm^3 to 5,000/mm^3.What action should the nurse take?

Choice A rationaleFilgrastim is a medication used to stimulate the growth of white blood cells, making patients less vulnerable to infections. If the patient’s white blood cell count has increased from 2,500/mm^3 to 5,000/mm^3 after administering five doses of filgrastim, it indicates that the medication has been effective.Choice B rationaleReviewing the patient’s culture and sensitivity reports is not directly related to the effect of filgrastim on white blood cell count.Choice C rationaleNeutropenic precautions are typically implemented when a patient has a low white blood cell count. Since the patient’s white blood cell count has increased, implementing neutropenic precautions may not be necessary.Choice D rationaleWhile it’s always important to monitor a patient’s vital signs, there’s no specific reason to do so just because the patient’s white blood cell count has increased after administering filgrastim.
