85
Differentiate abx choice for sepsis in 1 mo old vs. 2 mo old
Covering GBS and E. Coli => use 3rd gen cephalosporin in both, but a dif 3rd gen Ceftriaxone = go-to 3rd gen, but can't use in under 1 mo b/c of biliary sludging For under 1 mo use Cefotaxime To cover for Listeria add Ampicillin
86
Empiric treatment for meningitis in an 8 year old
Ceftriaxone (3rd gen cephalo) + acyclovir (covers HSV) + vanco (covers resistant pneumococcal disease aka MRSA)
