A Young Adult Calls the Clinic to Ask for a Prescription

A young adult calls the clinic to ask for a prescription for "that new flu drug." He says he has had the flu for almost 4 days and just heard about a drug that can reduce the symptoms. What is the nurse's best response to his request?

A) "Now that you've had the flu, you will need a booster vaccination, not the antiviral drug."
B) "We will need to do a blood test to verify that you actually have the flu."
C) "Drug therapy should be started within 2 days of symptom onset, not 4 days."
D) "We'll get you a prescription. As long as you start treatment within the next 24 hours, the drug should be effective."
