A Microbiology Technologist Is Working at the Bench and Notices

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 b-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 b-lactamases.
C) draw more blood cultures, because the ones that grew that organism are contaminated.
D) be on the lookout for diarrhea.
