Many times people visit the doctor requesting antibiotics to treat colds and viral infections. How is the doctor justified in offering the patient treatment options that do not include antibiotics for these cases?Group of answer choicesIf a doctor provides an antibiotic to treat colds and viruses, any bacteria in the patient's body will be killed, but a few will survive. Those few survivors may become resistant to antibiotics needed for real bacterial illnesses.Colds and viruses should be first treated with viral therapies and then when the body begins to recover, antibiotics can be used. Otherwise, the use of antibiotics is not effective at all.Antibiotics can weaken the immune system when used for colds and viruses, whereas other medications are not so hard on the immune system during these types of illnesses.Side effects from antibiotics are severe when used for colds and viruses. Any use of antibiotics for colds and viruses will only make the patient more ill and ultimately make the patient's recovery time longer.

A scientist tested three antibiotics on the growth of Staphylococcus aureus, a bacterium that causes infections in humans.These are their results:The scientist concluded that cloxacillin is the best antibiotic to use for all bacterial infections.Why might the scientist's conclusion be wrong?Choose a reason from the options below.Even at the lowest concentration, cloxacillin killed the most bacteria.Kanamycin has the smallest clear zone, despite being at the highest concentration.Cloxacillin has the largest clear zone.They only tested the antibiotics on Staphylococcus aureus.I DON'T KNOWSUBMIT ANSWER

In some cases, a single antimicrobial agent is not sufficient to destroy all the pathogens that develop during the course of a disease; thus, two or more drugs may be used simultaneously to kill all the pathogens and to prevent resistant mutant pathogens from emerging. In tuberculosis, for example, in which multidrug-resistant strains of Mycobacterium tuberculosis are frequently encountered, four drugs (isoniazid, rifampin, pyrazinamide, and ethambutol) are routinely prescribed, and as many as 10 drugs may be required for especially resistant strains.(1 Point)TrueFalse
