Q

Why is Formaldehyde not used a lot?

A

The efficiency is dependent on relative humidity and temperature
Must be used in an air tight building which must remain closed for at least 24 hours after treatment

Q

Why is peroxide compounds not used

A

Explosive
Irritating to skin
Long contact time
No action on spores
Does not kill pinworm eggs
No virucidal activity

17
Q

Why is Prevail used?

A

Breaks down into oxygen and water
Short contact times
Better efficiency to viruses and mycobacterism

18
Q

Why is Ethylene Oxide Used?

A

Effective against bacteria, fungi, viruses and spores
Sterilant
Good for heat sensitive items

19
Q

Why is Ethylene Oxide not used

A

Flammable and explosive
Toxic, carcinogenic and irritating to tissues
Contact time is 1-18 hours
Ventilation required post sterilization for up to 48 hours

20
Q

What is a Biguanide

A

A broad antibacterial spectrum
Effective against viruses, fungi and bacteria
Chlorhexide (antiseptic)
pH range 5-7
Inactivated by soaps and detergents

21
Q

What is a halogen

A

Chlorine or iodine compounds
Broad spectrum compounds (bacteria, Protozoa, viruses, fungi)
Low toxicity, low cost, easy to use

22
Q

Why are halogens not used?

A

Lose potency over time and not active at high temperatures or pH
Lose activity in organic matter, sunlight and some metals
Hypochlorites Should never be mixed with acids or ammonia - will result in toxic chlorine gas

23
Q

What is animal husbandry

A

How we care for animals

24
Q

What is sterilization

A

Cold sterilization on surgical instruments
Heat/ steam in autoclaves

25
Q

What is sanitation

A

Any cleaning technique that mechanically removes microbes

26
Q

What is disinfection

A

Use of physical process or chemical agent that promotes killing, inhibition, or removal of pathogenic microorganisms

27
Q

What is sepsis

A

Growth or microorganisms or the presence of microbial toxins in the blood or other tissues

28
Q

What is Asepsis

A

Any practice that prevents the entry of infectious agents into sterile tissues and thus prevents infection

29
Q

What is antisepsis

A

Practiced in health care - sterile methods that uses antiseptics which are directly applied to exposed body surfaces, wounds and surgical incisions to destroy vegetative pathogens

30
Q

What does static mean

A

The inhibit of growth of the organism
