Which of the following antibiotics is NOT a beta-lactam/beta-lactamase inhibitor combination used for Bacteroides fragilis?

Metronidazole
Beta-lactam/Beta-lactamase inhibitor
Ceftaz/avibactam
Cefotetan

The correct answer is: Ceftaz/avibactam

Ceftazidime/avibactam is not a beta-lactam/beta-lactamase inhibitor combination used for Bacteroides fragilis. It is a combination of a beta-lactam (ceftazidime) and a beta-lactamase inhibitor (avibactam), but it is not effective against Bacteroides fragilis. Metronidazole, on the other hand, is an effective antibiotic for Bacteroides fragilis and is not a beta-lactam or beta-lactamase inhibitor. Similarly, cefotetan is a standalone beta-lactam antibiotic and does not contain a beta-lactamase inhibitor. Therefore, neither of these options are the correct answer to the question. Only ceftazidime/avibactam is not a beta-lactam/beta-lactamase inhibitor combination used for Bacteroides fragilis.
