(C) Add IV acyclovir to the current antibiotic regimen.

(D) Add oral posaconazole therapy to the current antibiotic regimen.

The Correct Answer is: C

Answer c is correct

Adding IV acyclovir to the current antibiotic regimen provides immediate therapy and adequate concentrations of the drug.

Therapy against possible HSV encephalitis should not be delayed (A), because the delay could result in devastating consequences.

Changing antibiotic therapy to ceftriaxone and daptomycin (B) is not recommended, because therapy against possible HSV encephalitis would be delayed, which could result in devastating consequences, and ceftriaxone should not be used in infants less than 1 month old. Daptomycin is not indicated in neonatal meningitis. Antifungal therapy (D) is not indicated and therapy against possible HSV encephalitis would be delayed, which could result in devastating consequences.
