Regarding antibiotic therapy, which practice helps prevent resistance?

• A. True
• B. False
• C. Only for certain antibiotics
• D. Only if symptoms persist

Answer: (B)

The important idea is that finishing the full course of an antibiotic helps prevent resistance. If you stop early because you feel better, some bacteria may survive. Those survivors can carry or develop resistance traits, and the drug may not have been present long enough to fully eradicate the infection. This creates selective pressure that favors resistant strains, making future infections harder to treat. So the statement suggesting that stopping early helps prevent resistance is not correct. The best practice is to take the antibiotic exactly as prescribed for the full duration, use the right agent for the infection, and avoid saving leftovers or using antibiotics without a prescription. Resistance risk isn’t limited to certain antibiotics or to scenarios where symptoms persist; it’s driven by how antibiotics are used in any situation.
