Infection Control Flashcards
3 layers of the skin:
Epidermis, Dermis, Subcutaneous
What is an MSDS:
Material Safety Data Sheet
4 classifications of potentially infectious microorganisms:
Bacteria, fungi, viruses, and parasites
Microorganisms are:
Microscopic plants or animals. Also, known as microbes. Bacteria can exist almost everywhere…Bodies, clothing, water, surfaces, and even in the air. Study of these organisms are microbiology.
A microbiologist studies:
Pathogenic organisms to prevent the disease.
Nonpathogenic bacteria…harmless or not:
No.
Nonpathogenic bacteria help the body…do what:
Breakdown food, protect against infection, and stimulate the immune system.
Pathogenic bacteria…harmless or not:
Yes.
Pathogenic bacteria are considered harmful because:
They may cause disease or infection when they invade the body.
Microbes/germs are:
Nonscientific synonyms for disease-producing bacteria.
Bacteria:
One-celled microorganisms with both plant and animal characteristics. Some are harmful, some are harmless. Also, known as microbes or germs.
Cocci (pathogenic bacteria) are:
Round-shaped bacteria that appear either singly or in the following groups.
Staphylococci (pathogenic bacteria):
Pus-forming bacteria that grow in clusters like a bunch of grapes. They cause abscesses, pustules, and boils.
Streptococci (pathogenic bacteria):
Pus-forming bacteria arranged in curved lines resembling a string of beads. they cause infections such as strep throat and blood poisoning.
Diplococci (pathogenic bacteria):
Spherical bacteria that grow in pairs and cause disease such as pneumonia.
Bacilli (pathogenic bacteria):
Short, rod-shaped bacteria. They are the most common bacteria and produce disease such as tetanus (lockjaw), typhoid fever, tuberculosis, and diphtheria.
Toxin:
Any of various poisonous substances produced by some microorganisms.
Parasite:
An organism that grows, feeds, and shelters on or in another organism, while contributing nothing to the survival of that organism.
Virus:
A parasitic submicroscopic particle that infects cells of biologic organisms.
Parasitic Disease:
Disease is caused by parasites, such as lice and ringworm.
Pathogenic Disease:
Disease produced by disease-causing organisms, including bacteria, virus, and fungi.
Systemic Disease:
Disease that affects the body generally, often due to under- or over functioning of internal glands/organs.
Spirilla (pathogenic bacteria):
Spiral or corkscrew shaped. Which causes syphilis, or lyme disease.
Bacteria generally consists of liquid called:
Protoplasm
Pus is:
a fluid, created by tissue inflammation, that contains white blood cells, the debris of dead cells, tissue elements, and bacteria.
A local infection is:
Pimple or abscess. Infection that is confined to a particular part of the body and is indicated by a lesion containing pus.
A general infection results when:
The bloodstream carries the bacteria or virus and their toxins to all parts of the body.
Communicable or contagious disease is when:
A disease spreads from one person to another by contact.
Virus is:
A microscopic organism, capable of infesting almost all plants and animals, including bacteria.
Bloodborne pathogens are:
Disease-causing bacteria or viruses that are carried through the body in the blood or body fluids, such as hepatitis and HIV.
Scabies:
Contagious skin disease caused by the itch mite, which burrows under the skin.
Acquired immunity:
Immunity developed after the body overcomes a disease, or through inoculation.
Antiseptics:
Agents that may kill, retard, or prevent the growth of bacteria.
Asymptomatic:
Showing no symptoms or signs of infection.
Autoclave:
Apparatus for sterilization by steam under pressure.
