Final answer:
The laboratory test that will be performed to determine whether a specific bacterium is resistant to a specific drug is the culture and sensitivity test.
Step-by-step explanation:
The laboratory test that will be performed to determine whether a specific bacterium is resistant to a specific drug is the culture and sensitivity test. In this test, a sample of the bacterium is grown in a culture and exposed to different antibiotics. The growth of the bacterium is then observed to see if it is inhibited by the antibiotics, indicating sensitivity, or if it continues to grow, indicating resistance.
