Final answer:
The most correct statement about instrument care is that rinsing with distilled water is preferable to tap water. For microbial control on tissues, antiseptics are used, and all equipment used in bacterial culture experiments need to be sterile.
Step-by-step explanation:
The most correct statement about instrument care is C. Rinsing with distilled water is preferable to tap water. Distilled water is preferable because it does not contain minerals and other substances found in tap water that could deposit on the instruments and potentially interfere with sterilization processes or cause corrosion over time. Cleaning agents used on instruments should not corrode the instruments, have a neutral to slightly alkaline pH (around 7 to 8), and not mild abrasive.
After use, instruments should be kept moist to prevent the drying of organic material as it makes them harder to clean, and then they should be properly disinfected or sterilized based on their use and the level of cleanliness required.
For microbial control on tissues to prevent infection, the appropriate choice is B. antiseptic, as antiseptics are antimicrobial substances that are applied to living tissue/skin to reduce the possibility of infection. Disinfectants are used on non-living surfaces to destroy microbes and are generally too harsh for living tissue, whereas sterilants are used for the complete elimination of all forms of microbial life, including spores, and are applicable to inanimate objects.
