The nurse knows that acyclovir would most likely be prescribed for which type of infection?

A. A candida fungal infection.: Candida infections are treated with antifungal medications such as fluconazole or nystatin, not acyclovir. Acyclovir is ineffective against fungi because it specifically targets viral DNA synthesis. B. An MRSA bacterial infection.: Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial infection treated with antibiotics such as vancomycin or linezolid. Acyclovir has no antibacterial properties and would not be effective for MRSA. C. A herpes viral infection.: Acyclovir is an antiviral drug primarily used to treat infections caused by the herpes simplex virus (HSV-1 and HSV-2) and varicella-zoster virus. It works by inhibiting viral DNA replication, helping reduce symptom severity and frequency of outbreaks. D. A giardia protozoal infection.: Giardia infections are caused by protozoa and are typically treated with antiprotozoal medications such as metronidazole. Acyclovir has no activity against protozoa and would not treat this type of infection.
