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 myocardial intensive care unit 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, as the ones that grew that organism are contaminated.
D) Be on the lookout for diarrhea.
