Take the Antibiotics Quiz
Antibiotics have been called "wonder drugs." They can treat infections that once killed many people. But using these medicines when they shouldn’t be has let certain bacteria to become resistant to them. Learn more about this important issue by taking this quiz.
1. Antibiotics kill both viruses and bacteria that cause illness.

The correct answer is
Antibiotics kill only bacteria. They don’t work against viruses. Most common colds and sore throats are caused by viruses. Sometimes when you take an antibiotic, the bacteria may be resistant or become resistant. Resistant bacteria aren't killed by the antibiotic. They continue to cause infection. You should take antibiotics only when you need to. Each time you take an antibiotic when you don’t need to, you raise your chances of having drug-resistant bacteria. This can happen if you take an antibiotic for a viral infection. It can also happen if you don’t take all of your antibiotic prescription. Resistant bacteria have made certain infectious diseases harder to treat. These diseases include tuberculosis, pneumonia, and meningitis. Once a certain type of bacteria is resistant to a medicine, it can pass on that resistance to other types of bacteria.
2. Antibiotics will help you get better from a cold or the flu.

The correct answer is
Viruses cause most colds and the flu. They also cause most coughs and most sore throats. Antibiotics can’t kill viruses. But certain antiviral medicines can work for the flu. Taking an antibiotic for a cold or the flu will not help you get better faster. It may also make some bacteria resistant. This also can happen in children. Children often play together and can easily pass resistant bacteria onto others. This makes the problem worse. Your healthcare provider will probably prescribe an antibiotic if you have an ear infection, a chronic sinus infection, strep throat, or a urinary tract infection. Many of these infections are caused by bacteria.
3. Many antibiotics only work against certain types of bacteria.
You didn't answer this question.
You answered
The correct answer is
These antibiotics are called narrow-spectrum antibiotics. The other category of antibiotics is broad-spectrum. Broad-spectrum antibiotics are used to treat a broader number of bacteria types. They are also used if the bacteria causing the infection are unknown. Unfortunately, more and more healthcare providers prescribe the broad-spectrum antibiotics for less serious infections. Experts worry that using these broad-spectrum antibiotics too often will cause more bacterial resistance. These broad-spectrum antibiotics may also cost more than narrow-spectrum antibiotics.
4. If you are taking antibiotics, it's OK to stop taking the medicine when you start to feel better.
You didn't answer this question.
You answered
The correct answer is
It's important to take all of the medicine prescribed for your illness. If you stop taking the medicine before you have finished it all, some of the bacteria that caused your illness may still be in your body. If the bacteria are exposed to only a small dose of an antibiotic or if an antibiotic is not given enough time to kill the bacteria, the remaining bacteria may develop resistance to the antibiotic. The smaller amount of bacteria that remain may also replicate and cause symptoms all over again. Resistant bacteria can also pass from person to person. This makes infections increasingly harder to treat.
5. Keeping extra antibiotics around is a good idea in case you need them at a future date.
You didn't answer this question.
You answered
The correct answer is
You should not take antibiotics left over from an earlier illness. These antibiotics may not be the correct choice for your current infection. Even if they are correct, they would likely make up only a part of a treatment course. This would not be enough to completely fight off a bacterial infection and could create bacterial resistance. Antibiotics also may not work if they are old, because they go bad after a time. The antibiotic you stored on your shelf may have expired. More important, your current illness may not be caused by bacteria, but by a virus. This would make the antibiotics useless. Never share antibiotics with others. The medicine is meant only for you and for the very specific infection it is treating. Always check with your healthcare provider before taking any antibiotic.
6. Antibiotics kill both good and bad bacteria.

You answered
The correct answer is
That's why taking an antibiotic can cause symptoms that mean you don’t have enough good bacteria. These symptoms include diarrhea, vaginal yeast infections, oral thrush, and an inflammation of the small intestine and colon (C. difficile enterocolitis). If you have any of these side effects, be sure to tell your healthcare provider.
7. If you believe that an antibiotic would help your illness, you should demand that your healthcare provider give you one.
You didn't answer this question.
You answered
The correct answer is
Using antibiotics when you don’t need them helps bacteria become resistant. It may also expose you to unnecessary side effects. Many of the prescriptions written each year aren’t needed. That’s because they are prescribed for the common cold and other viral infections. Ask your healthcare provider why an antibiotic was not prescribed for your illness, but don't demand one. Your provider is the best source of information on using antibiotics.
8. All antibiotics are safe to take during pregnancy and breastfeeding.
You didn't answer this question.
You answered
The correct answer is
Many antibiotics are safe to take if you are pregnant or breastfeeding. But some are not. Some of these medicines can affect your growing fetus. Your healthcare provider will make the correct choice of medicine for you. Be sure to tell your healthcare provider if you are breastfeeding.
9. Using an antibacterial soap is a good way to keep bacteria at bay.
You didn't answer this question.
You answered
The correct answer is
Although hospitals and other medical facilities use antibacterial soaps, they follow strict guidelines for their use. Some health experts worry that using antibacterial soaps at home can make bacteria resistant to these soaps. Studies have not proved that these soaps work any better than ordinary soaps to get rid of bacteria. In fact, they may be harmful to health. Most of the soaps containing antibacterial chemicals are now being removed from the market. Good ways to prevent infections include washing your hands often and staying up to date on vaccines.
10. Over time, people can become resistant to bacteria.
You didn't answer this question.
You answered
The correct answer is
Many people believe this, but it's not true. People don't become resistant to bacteria. It is the bacteria themselves that become resistant to antibiotics.
