Final answer:
Surgeons should use Metzenbaum scissors for cutting delicate tissue, as they are designed for precision. Antiseptics are the appropriate choice for microbial control of living tissues to prevent infection.
Step-by-step explanation:
To cut delicate tissue during surgery, a surgeon should use Metzenbaum scissors. These scissors are specifically designed for cutting and dissecting soft delicate tissues. On the other hand, Operating scissors, Mayo scissors, and Lister bandage scissors have different specializations. Operating scissors are more general in use, Mayo scissors are best for cutting through tougher tissue, like fascia, and Lister scissors are commonly used for sizing dressings and removing bandages without causing injury.
Regarding microbial control to prevent infection, antiseptics are suitable for use on living tissues. Disinfectants are intended for use on inanimate objects to reduce the level of microorganisms, while sterilants are agents that destroy all forms of microbial life. Water alone doesn't confer any microbicidal properties, although it's essential for maintaining cleanliness.
