Question
Based on your disc susceptibility results for E. coli R-, which ONE of the following is correct if considering treatment of an infection caused by this organism?
Select one:
A.
All drugs evaluated could be considered for treatment in this case
B.
Zone sizes were too large so the results are inconclusive and should be repeated
C.
Ciprofloxacin is the most potent drug so this should be used preferentially over all others
D.
Nitrofurantoin and fosfomycin are the most potent so either drug should be used preferentially over all others
E.
High drug potency is associated with increased toxicity so the drug with the lowest potency should be considered preferentially
