Which statement best defines an antiseptic?

• A. A chemical that promotes infection
• B. An agent that prevents or reduces infection by eliminating microorganisms
• C. A virus used in vaccines
• D. A disinfectant used on metals

Answer: (B)

An antiseptic is a chemical applied to living tissue to prevent or reduce infection by destroying or inhibiting microorganisms. It is designed for use on skin and mucous membranes, helping lower the risk of infection during wounds or procedures. Examples include alcohol, iodine, and chlorhexidine. This is different from a disinfectant, which is meant for inanimate surfaces, not living tissue. The idea of a virus used in vaccines isn’t related to antisepsis, and using a disinfectant on metals describes a different application entirely. The statement that best defines antiseptic is the one describing an agent that prevents or reduces infection by eliminating microorganisms on living tissue.
