A client with symptoms of influenza that started the previous day, asks the clinic nurse about taking oseltamivir to treat the infection. Which response should the nurse provide?

A. Refer the client to the healthcare provider at the clinic to obtain a medication prescription: Oseltamivir is an antiviral medication that requires a prescription. Early initiation, ideally within 48 hours of symptom onset, can reduce the severity and duration of influenza, making prompt referral essential. B. Explain to the client that antibiotics are not useful in treating viral infections such as influenza: While this is true, it does not address the client’s question about oseltamivir, which is an antiviral, not an antibiotic. C. Instruct the client that over-the-counter medications are sufficient to manage influenza symptoms: Over-the-counter meds can help alleviate symptoms but do not treat the viral infection itself. Oseltamivir can shorten illness duration if started early, so OTC meds alone may not be sufficient. D. Advise the client that once symptoms occur it is too late to receive an influenza vaccination: Vaccination is preventative and should be given before exposure or illness onset. However, this response does not address treatment options once symptoms have started.
