A microbiology technologist is working at the bench and notices that a patient from the cardiac intensive care unit (CICU) grows a Klebsiella pneumoniae bacterium that is an extended-spectrum $\beta$-lactamase-producing isolate. This technologist would advise the physician to
A) order any antimicrobial that is effective against gram-negative rods in general.
B) limit the use of antimicrobial agents that tend to induce the formation of extended-spectrum $\beta$-lactamases.
C) draw more blood cultures, because the ones that grew that organism are contaminated.
D) be on the lookout for diarrhea.

Question

Quizplus · Accepted Answer

Limiting the use of antimicrobial agents that tend to induce the formation of extended-spectrum F1F1F1S1F1F1F10-lactamases would help prevent the spread of this resistant strain of Klebsiella pneumoniae. Ordering any antimicrobial that is effective against gram-negative rods in general may not be effective against this specific, resistant strain. Drawing more blood cultures would not be necessary as the growth of this organism indicates a true infection. Being on the lookout for diarrhea is not relevant to this particular infection.
