A nurse is monitoring a client who is receiving antiviral therapy for influenza.
The nurse expects that the antiviral drug will have which of the following effects?
Choice A is wrong because antiviral drugs do not kill the influenza virus, but only prevent it from multiplying.
Antiviral drugs for influenza can reduce the duration and severity of symptoms by inhibiting the replication of the virus in the body. They are most effective when started within 48 hours of illness onset.
Choice C is wrong because antiviral drugs do not prevent the transmission of the virus to others, but only reduce the amount of virus shed by infected persons. People who take antiviral drugs should still practice good hygiene and avoid close contact with others.
Choice D is wrong because antiviral drugs do not stimulate the immune system to fight off the virus, but only interfere with the viral enzymes that are essential for viral replication. Antiviral drugs are not a substitute for vaccination, which can induce protective immunity against influenza.
