Which substance that will destroy or inhibit growth of microorganisms and can be used on living tissue?

• A. Antiseptic
• B. Cleaner
• C. Disinfectant
• D. Sterilant

Answer: (A)

An antiseptic is designed to destroy or inhibit the growth of microorganisms on living tissue, such as skin or mucous membranes, while being safe enough to apply to the body when used as directed. That safety for tissue is the key distinction from the other options. Cleaners focus on removing dirt and debris and don’t necessarily kill microbes. Disinfectants are intended for inanimate surfaces and can be too harsh for living tissue. Sterilants aim to kill all microorganisms, including spores, on instruments or materials and are not used on living tissue. So the substance that fits both the antimicrobial action and safe use on living tissue is an antiseptic.
