which antibiotics are preferred for immunocompromised patients: bactericidal or bacteriostatic -
ANSWER bactericidal
which antibiotics are preferred for patients with an overwhelming infection: bactericidal or
bacteriostatic - ANSWER bactericidal
broad spectrum antibiotics - ANSWER affect a broad range of gram-positive or gram-negative
bacteria
narrow spectrum antibiotics - ANSWER Effective against specific bacteria
which is used for empiric therapy: narrow or broad - ANSWER broad spectrum
Risks of Broad Spectrum - ANSWER disruption of normal floral
increases risk of development of antibiotic resistance
What is the primary goal of antibiotic therapy - ANSWER kill bacteria without harming host tissue
Bactericidal antibiotics - ANSWER directly kill bacteria
, dicloxacillin
narrow-spectrum penicillinase resistant susceptible pathogens - ANSWER S. Aureus
streptococci
bacteriostatic antibiotics - ANSWER Antibiotics that do not actually kill bacteria but rather inhibit
bacterial proliferation while the hosts immune system does the killing
which antibiotics increase the risk of antibiotic resistance: narrow or broad spectrum and why -
ANSWER Broad spectrum because they kill more competing organisms than narrow spectrum drugs
is narrow or broad spectrum antibiotics preferred - ANSWER narrow is preferred when possible.
broad spectrum only used when pathogen is unknown or when multiple types of bacteria is
suspected
