What is the primary function of an antiseptic?

• A. Disinfect surfaces
• B. Prevention of infection
• C. Remove debris
• D. Neutralize pH

Answer: (B)

The primary function of an antiseptic is the prevention of infection. Antiseptics are substances that are applied to living tissue to reduce the possibility of infection, sepsis, or putrefaction. They work by killing or inhibiting the growth of pathogens on surfaces of the skin or mucous membranes, which helps prevent infections during medical procedures or in everyday settings.

Disinfecting surfaces is a function associated with disinfectants, which are typically used on inanimate objects rather than living tissue. Removing debris pertains to cleaning, which involves the removal of dirt and organic matter, but does not necessarily address the elimination of pathogens. Neutralizing pH refers to changing the acidity or alkalinity of a solution, which is not a direct function of antiseptics either. Thus, the correct focus of antiseptics is their capability to prevent infection through their antimicrobial properties when applied to skin or wounds.
