Verified step by step guidance1
Step 1: Understand the definitions of antiseptics and disinfectants. Antiseptics are chemical agents applied to living tissues to reduce the possibility of infection, sepsis, or putrefaction.
Step 2: Recognize that disinfectants are chemical agents used on non-living surfaces to destroy or inhibit the growth of harmful microorganisms.
Step 3: Note the key difference lies in their safe application: antiseptics are safe for use on skin and mucous membranes, whereas disinfectants are too harsh for living tissues and are used on inanimate objects.
Step 4: Evaluate the incorrect options by comparing their claims to the definitions: antiseptics are not limited to viruses, do not necessarily kill all microorganisms, and are not used to sterilize instruments.
Step 5: Conclude that the best description is that antiseptics are safe for use on living tissues, while disinfectants are used on non-living surfaces.
