Which statements is correct about antibiotics?
They are used to treat viral infections
They are always effective against all types of bacteria
Overuse of antibiotics can lead to antibiotic resistance
They are only available in injectable form
Correct answer: (C)
(C) Overuse and misuse of antibiotics can lead to the development of antibiotic-resistant bacteria. This occurs when bacteria evolve to become resistant to the antibiotics that are commonly used to treat them, making infections more difficult to treat and increasing the risk of serious complications.
Incorrect option
A) Incorrect. Antibiotics are not effective against viral infections, as viruses are different from bacteria and have different structures and mechanisms of action. Antibiotics only target bacteria, which are single-celled organisms.
B) Incorrect. Antibiotics are effective against certain types of bacteria, but not all. Different antibiotics are designed to target specific types of bacteria, and some bacteria have developed resistance to certain antibiotics. Additionally, some bacteria may be resistant to multiple antibiotics, making treatment more difficult.
D) Incorrect. Antibiotics are available in many forms, including pills, capsules, liquids, and topical creams or ointments. Injectable forms are also available, but they are not the only option. The form of the antibiotic used will depend on the type of infection being treated and the preference of the healthcare provider and patient.
