Final answer:
The correct agent for microbial control on tissues to prevent infection is an antiseptic. It is safe for living tissues, unlike disinfectants, which are meant for surfaces, and sterilants, used for complete microbial eradication on equipment. The correct answer is B) Hydromassage Bathtub System.
Step-by-step explanation:
The appropriate agent to use on tissues for microbial control to prevent infection is an antiseptic. Unlike disinfectants, which are used on non-living surfaces, antiseptics are specially formulated to be safe on living tissues.
They help eliminate microbes that cause infections without harming the tissue itself. A common example of an antiseptic is hydrogen peroxide, which is often used for cleaning wounds.
On the other hand, disinfectants are used on surfaces and are too harsh for living tissue. Sterilants are generally used for a complete eradication of all forms of microbial life and are typically used on medical and laboratory equipment.
Water is not antimicrobial unless it has been specially treated or it is at boiling temperature, which can kill some types of microbes.
