Correct: A zone of inhibition around the disk shows the organism is sensitive to the agent. After the organism is identified, it is grown on culture medium. Observing whether the organisms are sensitive or resistant to certain test antibiotics assists in determining which antibiotic to use in difficult infections.
Incorrect choices: One to two days are required before the results of the test are available. Although antibiotic therapy can start before this time, it may be changed after the results are available. If clinical response has been adequate, the original antibiotic is often continued despite sensitivity results.
