Question

multiple choice question
for which of the following reasons would antimicrobial susceptibility testing be performed?
● if the pathogen commonly shows resistance to the antibiotic.
● if the patient has allergies to the antibiotic.
● if the pathogen is a protozoan.
need help? review these concept resources.

Explanation:

Antimicrobial susceptibility testing is done to determine which antimicrobial agents will effectively inhibit the growth of the pathogen. If a pathogen commonly shows resistance to an antibiotic, testing is needed to find an effective alternative. Patient allergies relate to avoiding the antibiotic, not testing susceptibility. Protozoa are generally not treated with typical antibiotics (which target bacteria), so testing isn't needed for them.

Answer:

A. If the pathogen commonly shows resistance to the antibiotic.
