Question

what is the ultimate goal when selecting an antimicrobial regimen?
a. collect specimens.
b. determine where the infection was acquired.
c. identify the causative pathogen.
d. identify an appropriate oral antibiotic.

Explanation:

When selecting an antimicrobial regimen, the ultimate goal is to identify the causative pathogen. This is because different pathogens have different susceptibilities to antimicrobial agents. Once the causative pathogen is identified, an appropriate antimicrobial (which could be oral or otherwise depending on the situation) can be chosen. Collecting specimens (a) is a preliminary step to help in identifying the pathogen. Determining where the infection was acquired (b) might give some clues about potential pathogens (e.g., hospital - acquired vs community - acquired), but it is not the ultimate goal. Identifying an appropriate oral antibiotic (d) is a sub - step after identifying the causative pathogen.

Answer:

C. Identify the causative pathogen.
