Medical devices that have contact with sterile body tissues or fluids are considered critical items. These items should be sterile when used because any microbial contamination could result in disease transmission. Such items include
surgical instruments, biopsy forceps, and implanted medical devices
.
Which of the following is suitable for use on body tissues for microbial control to prevent infection?
Antiseptic
is suitable for use on tissues for microbial control to prevent infection.
Which of the following chemical agents is used for sterilization?
Hydrogen peroxide

Hydrogen peroxide (H
2
O
2
) is a widely used biocide for disinfection, sterilization, and antisepsis.
Which of the following microbial control methods does not actually kill microbes or inhibit their growth but instead removes them physically from samples group of answer choices?

What are the chemical method of sterilization?
The established methods of sterilization include (1) high temperature/pressure sterilization (by dry heat or moist heat); (2) chemical sterilization
(e.g., ethylene oxide gas);
(3) filtration; and (4) radiation sterilization (Gamma/Electron beam).
What are the 4 methods of sterilization?
Sterilization can be achieved by a combination of
heat, chemicals, irradiation, high pressure and filtration
like steam under pressure, dry heat, ultraviolet radiation, gas vapor sterilants, chlorine dioxide gas etc.
Does disinfectant kill all microorganisms?
Disinfection describes a process that
eliminates many or all pathogenic microorganisms
, except bacterial spores, on inanimate objects (Tables 1 and 2). … Intermediate-level disinfectants might be cidal for mycobacteria, vegetative bacteria, most viruses, and most fungi but do not necessarily kill bacterial spores.
Which chemicals are used to fix microbial cells?
| Compound Type of Action | Phenol (5%) Disinfectant | Hexachlorophene (pHisohex) Disinfectant/antiseptic | Formaldehyde (4%) Disinfectant | Zephrin and other quaternary ammonium compounds Disinfectant |

What is the only way to destroy both bacteria and their spores?
A process called
sterilization
destroys spores and bacteria. It is done at high temperature and under high pressure. In health care settings, sterilization of instruments is usually done using a device called an autoclave.
What germicides may lead to sterility?
High-level germicides
kill vegetative cells, fungi, viruses, and endospores, and can ultimately lead to sterilization.
Why is Sterilisation used?
Sterilisation is a term referring to
any process that eliminates or kills all forms of life
, including transmissible agents such as viruses, bacteria, fungi and spore forms.
Which of the following show the maximum resistance to physical and chemical agents?
Bacterial endospores
are the microbial forms have the highest resistance to physical and chemical controls.
