問題一覧

They are used to control growth of microbes on both living tissue and inanimate objects.

Chemical agents

What is a common problems to disinfection?

Selection of an agent

True/False: Most chemical agents merely reduce the microbial population to safe levels or remove vegetative forms from objects.

True

What are the Principles of Effective Disinfection?

Read the label, Nature of material being disinfected, Disinfectant effect

They are chemical substances that applied to non-living objects or surfaces to inhibit the growth of microorganisms.

Disinfectants

They prevent the spreading of germs and bacteria to people by sterilizing the surfaces where they are applied.

Disinfectants

Give an example of disinfectant that are used in healthcares and hospitals to clean surgery tools and rooms.

Hydrogen peroxide

Give some common disinfectants.

Alcohols, Oxidizing agents, Bleaches

They are largely used in homes for cleaning bathrooms, kitchens and floor.

Disinfectants

True/False: Disinfectant eliminate all the microorganisms.

False

They are chemical agents used to destroy or prevent the growth of microorganisms that could cause infections and diseases.

Antiseptics

They are applied on broken skins to kill disease-causing microorganisms that might have infected the area or keep them away from these areas. .

Antiseptics

They are applied on living tissues with zero injurious effect on the body surface where it is applied

Antiseptics

It may also act as sanitizer for cleaning hands to remove bacteria when a person cannot wash hands.

Antiseptics

Read and type YES if done

YES

What are the chemical methods that are use to control microbial growth?

Phenol, Alcohol, Halogen, Oxidizing agents, Surfactants, Heavy metals, Aldehydes, Gaseous agents, Antimicrobials

It is also know as carbolic acid is used in original surgical antiseptic.

Phenol

It is used in disinfectants, antiseptics and solvent in tincture

Alcohol

Give example of halogens that are used to control microbial growth

Iodine, Chlorine, Bromine

They are used in disinfectants, antiseptics and water purification.

Halogens

Their mechanism of action is to denature proteins and distrupt cell membrane.

Phenol, Alcohol, Halogen

Examples of oxidizing agents that are used to control microbial growth

Peroxides, Ozone

Give examples of Heavy metals that are used to control microbial growth

Arsenic, Mercury, Silver, Copper

Give examples of aldehydes that are used to control microbial growth

Formaldehyde, Glutaraldehyde

Give example of gaseous agents that are used to control microbial growth

Ethylene oxide

They are used in disinfectants, antiseptics for deep wound, water purification and sterilization of food processing and medical equipments.

Oxidizing agents

They are used in soaps, degerming reagents, antiseptics.

Surfactants

They are used in Fungistat in paints, silver nitrate cream, surgical dressing, burn cream and catheter.

Heavy metals

What is the mechanism of action of Oxidizing agent?

Denature protein by oxidation

What is the mechanism of action of Surfacants?

Decrease surface tension of water and disrupt cell membranes

These chemical methods have the same mechanism of action which is to denature protein.

Heavy metals, Aldehydes, Gaseous agents

They are used in Disinfectant and embalming fluid

Aldehydes

They are used in the sterilization of heat and water sensitive objects

Gaseous agents

They are used in disinfectants and treatment of infectious diseases

Antimicrobials

Its mechanism of action is to act against cell wall, cell membranes, protein synthesis and DNA replication.

Antimicrobials

What are the two actions of microbial control agents?

Alteration of membrane permeability, Damage to protein and nucleic acids

It is the target of many microbial agents

Plasma membrane

It actively regulates the passage of nutrients into the cell and the elimination of wastes from the cell.

Plasma membrane

True/False: Damage to the lipids and proteins of the plasma membrane by antimicrobial agents causes cellular contents to leak into the surrounding medium and interferes with the growth of the cell.

True

True/False: The hydrogen bonds of proteins is NOT susceptible to heat, breakage results to denaturation of the protein.

False

They are sometimes thought of as a little bags of enzymes which are primarily proteins and are vital to all cellular activities.

Bacteria

These nucleic acids are the carriers of the cell's genetic information

DNA, RNA

What would happen to the cell if the RNA and DNA is damage by heat, radiation and chemicals?

The cell can no longer replicate nor carry its normal metabolic functions

Common name for Sodium Hypochlorite

Bleach

This materials can invade sterile tissues and can produce infection if not treated well.

Critical materials

This materials may have made contact with the mucous membrane

Semi-critical materials

Intermediate to low level of disinfection should be done with this material before contact with the skin.

Non-critical material

A disinfectant with an activity against bacterial endospores.

High-level disinfectant

This type of disinfectant has a tuberculosidal activity but not endosporericidal activity.

Intermediate level disinfectant

This type of disinfectant have activity towards other microorganisms but have no endospore or tuberculosidal activity.

Low-level disinfectant

Room temperature

20 to 60 degrees celsius

What is the most effective method of sterilization?

Autoclaving

Boiling temperature

100 degrees celsius

Hot air oven temperature

170 to 180 degree celsius

What physical methods provides disinfection but not sterilization?

Boiling, Pasteurization

It is commonly used in sterilized glassware.

Dry heat

It filters microorganisms less than 0.3 microns.

High Efficiency Particulate Air (HEPA) filter

What are the different Categorized Medical materials?

Critical materials, Semi critical materials, Noncritical materials
