Narrow vs Broad spectrum: Narrow is preferred to reduce resistance to antibiotics. - refers to the spectrum of what it can treat.
Empiric Therapy: using what works.
Bacteriostatic: suppress growth of bacteria, if pt if immunocompromised (wbc) – not as effective
Bactericidal: kill bacteria ..work with patients works with patents to be immunocompromised
