Which client would be appropriate for administration of an antiviral medication?

A. A client with a bacterial skin infection: Antiviral medications target viral replication and are ineffective against bacterial pathogens. Management of bacterial skin infections requires antibiotics rather than antivirals. Using antivirals in this scenario would not treat the underlying infection. B. A client with pneumococcal pneumonia: Pneumococcal pneumonia is caused by Streptococcus pneumoniae, a bacterium. Antivirals do not impact bacterial infections, and treatment focuses on appropriate antibiotic therapy. Antiviral administration is not indicated. C. A client with strep throat: Streptococcal pharyngitis is bacterial in origin. Antivirals have no therapeutic effect on Streptococcus pyogenes, and standard care involves antibiotics. Prescribing antivirals would not resolve the infection. D. A client with influenza type B: Influenza is a viral infection caused by influenza viruses, including type B. Antiviral medications such as oseltamivir or zanamivir can reduce symptom severity and duration if initiated early. Administration is appropriate to target viral replication and limit complications.
