As a general guideline, it is suggested that within a particular antimicrobial class, primary (group A) agents should be reported first and secondary (group B) agents should be reported only if
A) the physician insists that a secondary agent be reported. B) the hospital pharmacy no longer stocks the group A agent. C) the patient cannot tolerate the primary agents. D) the FDA has recalled the primary agents.
Why would normal flora isolating from immunosuppressed patients undergo antimicrobial susceptibility testing?
A) These are not normal flora; they are other potential pathogens that have the same colonial morphology as normal flora. B) Species usually viewed as normal flora may be responsible for an infection in an immunosuppressed patient. C) All bacteria isolated from immunosuppressed patients must have antimicrobial susceptibility tests performed. D) Cultures from immunosuppressed patients only grow pathogenic organisms that must undergo antimicrobial susceptibility testing.
When should antimicrobial susceptibility testing be performed on a bacterial isolate from a clinical specimen?
A) When the isolate is determined to be a probable cause of the patient's infection B) When the susceptibility of the isolate to particular antimicrobial agents cannot be reliably predicted C) When the organism is part of the normal microbiota D) Both A and B
