QUESTIONS AND ANSWERS | 2026
UPDATE | 100% CORRECT.
What are the major antibiotic drug classes - ANS Beta-lactams: penicillins
Beta-lactams: Cephalosporins
fluoroquinolones
tetracyclines and macrolides
sulfonamides, trimethoprim, &nitrofurantoin
What is the primary goal of antibiotic therapy - ANS kill bacteria without harming host tissue
Bactericidal antibiotics - ANS directly kill bacteria
bacteriostatic antibiotics - ANS Antibiotics that do not actually kill bacteria but rather inhibit
bacterial proliferation while the hosts immune system does the killing
which antibiotics are preferred for immunocompromised patients: bactericidal or bacteriostatic
- ANS bactericidal
which antibiotics are preferred for patients with an overwhelming infection: bactericidal or
bacteriostatic - ANS bactericidal

, broad spectrum antibiotics - ANS affect a broad range of gram-positive or gram-negative
bacteria
narrow spectrum antibiotics - ANS Effective against specific bacteria
which is used for empiric therapy: narrow or broad - ANS broad spectrum
Risks of Broad Spectrum - ANS disruption of normal floral
increases risk of development of antibiotic resistance
which antibiotics increase the risk of antibiotic resistance: narrow or broad spectrum and why -
ANS Broad spectrum because they kill more competing organisms than narrow spectrum
drugs
is narrow or broad spectrum antibiotics preferred - ANS narrow is preferred when possible.
broad spectrum only used when pathogen is unknown or when multiple types of bacteria is
suspected
Bactericidal drugs - ANS Aminoglycosides
Beta-lactams
fluoroquinolones
Metronidazole
Vancomycin
streptogramins
most antimycobacterial agents (rifampin, isoniazid, streptomycin, etc)
bacteriostatic drugs - ANS clindamycin
macrolides
