Final answer:
The main difference between disinfectants and antiseptics is that antiseptics are safe for living tissues while disinfectants are used on inanimate objects. Disinfectants are typically more concentrated than antiseptics. The correct answer to the student's question is D) both A and B are correct, and for the reference question, B. antiseptic is suitable for tissues.
Step-by-step explanation:
The relationship between disinfectants and antiseptics involves their use and concentration. To clarify, B) antiseptics are used on living tissue, such as when cleaning a wound, whereas disinfectants are used to reduce the number of microbes on inanimate objects, like countertops or medical instruments. This distinction is crucial because disinfectants typically contain higher concentrations of chemicals and can be more harmful to living tissues, necessitating their use on objects rather than skin or mucous membranes. An example of an antiseptic is hydrogen peroxide, whereas bleach can be used as a disinfectant.
Regarding the choices given in the student's question, the correct answer would be D) both A and B are correct. Disinfectants are usually more concentrated and, therefore, not safe for use on living tissues, while antiseptics are formulated to be safe for such use. As for the second question provided for reference, B. antiseptic is suitable for use on tissues for microbial control to prevent infection.
