imagine that you are sick with pneumonia caused by a bacterial infection. your doctor prescribes an antibiotic to be taken every day for eight days. what do you predict could happen if two doses are skipped?
nothing will happen to any of the bacteria since all the antibiotics were not taken. you will remain sick.
weakly resistant bacteria will die off but the more resistant bacteria will will remain. you will likely remain sick or may even get worse.
skipping only 2 of the 8 doses is acceptable. the bacteria will all die and you will get better just as fast as if you took all the medicine.
extremely resistant bacteria will die off first, leaving only weakly resistant bacteria which your immune system will fight.

Explanation:

When antibiotics are not taken as prescribed (like skipping doses), the concentration of the antibiotic in the body may not be sufficient to kill all bacteria. Weaker - resistant bacteria are more likely to be affected by the antibiotic (even with skipped doses to some extent), but more resistant bacteria can survive. If more resistant bacteria remain, they can multiply, and the infection may persist or worsen.

• Option 1: Saying "nothing will happen to any of the bacteria" is incorrect. Some bacteria (the less resistant ones) are still affected by the antibiotic, so this option is wrong.
• Option 3: Skipping doses is not acceptable. The bacteria may not all die. Antibiotics need to be taken as prescribed to maintain an effective concentration to kill bacteria, so this option is wrong.
• Option 4: It is the opposite. More resistant bacteria are more likely to survive when antibiotic concentration is sub - optimal (due to skipped doses), not die off first, so this option is wrong.

Answer:

Weakly resistant bacteria will die off but the more resistant bacteria will will remain. You will likely remain sick or may even get worse.
