of c difficile infection the authors conclusions are consistent with those of three
other studies
c. in a study of the association between antibiotic exposure and development of
c difficile infection antibiotic therapy began an average of 3 weeks before c
difficile infection developed
d. in a study of the association between antibiotic exposure and development of
c difficile infection prolonged antibiotic therapy was a greater risk for c difficile
infection than short-term antibiotic therapy. - CORRECT ANSWERS a

CORRECT ANSWERS d
a patient is suspected of having pertussis a nasal pharyngeal aspirate is collected
for direct fluorescent antibody testing and for culture 8 hours after antimicrobial
therapy is started The DFA test is negative but the culture test is positive does
this patient have pertussis?
a. no because the DFA test is highly specific and it was negative
b. no because culture of bordetella pertussis has very low sensitivity
c. no because I'll testing is unreliable if antimicrobial therapy has been initiated
prior to specimen collection
d.Yes because the culture test is 100% specific for identification of bordetella

The most appropriate and epidemiology study designed to use is
a. retrospective cohort study
b. prospective cohort study
c. case control study
d. cross-sectional study - CORRECT ANSWERS c
important considerations regarding blood culture specimens include
1) collect prior to the initiation of antimicrobial therapy
2) collect from a central venous catheter whenever possible
3) ensure that the volume of the specimen collected is sufficient
