Pre-Activity Survey Question Title 1. In Clostridium difficile infection (CDI), patient factors that are predictive for poor outcomes include all of the following except: Older age Lack of concomitant antimicrobial exposure Elevated WBC Elevated creatinine Question Title 2. According to the IDSA guidelines, first-line therapy for an initial episode of CDI in a patient with a WBC count >15,000/mm3 is: Metronidazole Vancomycin Fidaxomicin Rifaximin Question Title 3. Clinical trials demonstrate that, compared to vancomycin, the use of fidaxomicin in the treatment of CDI resulted in significantly: Higher overall clinical cure rates Higher clinical cure rates for moderate-to-severe CDI only Lower clinical cure rates in patients with mild infection Lower rates of recurrent infection Question Title 4. The term used to describe a disturbed colonic microflora that leaves patients susceptible to CDI via a loss of colonization resistance is: Toxic megacolon Dysbiosis Probiotic syndrome Fecal microbiota dysfunction Question Title 5. Clinical trial results have demonstrated that each of the following can decrease CDI recurrence rates except: Fecal microbiota transplantation Tolevamer Colonization with non-toxigenic C. difficile Use of monoclonal antibodies to toxin B Question Title 6. Which of the following antimicrobial-resistant Gram-negative bacteria causes the greatest number of reported deaths in the US? ESBL-producing Enterobacteriaceae Carbapenem-resistant Enterobacteriaceae Multidrug-resistant Pseudomonas aeruginosa Multidrug-resistant Acinetobacter spp. Question Title 7. Patient risk factors for infection by antimicrobial-resistant Gram-negative bacteria include all of the following except: Previous exposure to broad-spectrum antimicrobials Age <60 years Previous ICU stay COPD Question Title 8. All of the following are FDA-approved beta-lactam/beta-lactamase inhibitors except: Ceftazidime-avibactam Ceftolozane-tazobactam Plazomicin-avibactam Piperacillin-tazobactam Question Title 9. The most common Gram-negative pathogen encountered in the hospital setting is: K. pneumoniae E. coli P. aeruginosa C. difficile Question Title 10. A next-generation aminoglycoside currently under development that exhibits activity against Gram-positive and Gram-negative pathogens is: Relebactam Eravacycline Plazomicin RPX7009 Done
