when you have a sickness that is caused by a virus, you could be helped by an antibiotic (T or F)

false

psychosocial effect of PPE

makes some people feel safe, scares other people

transmission of a disease is when...

the disease is passed to a new individual or group

a disease spread by airborne droplets is...

the flu

the reservoir in the chain of infection is...

the space where the microorganism lives

you pass diseases indirectly by...

touching a surface, doorknob...

examples of transmission

transmission from host to host, direct/indirect contact, ingestion, inhalation

diseases transmitted through indirect contact are ____ and ____

Hep A and pink eye

when to wash your hands

1: before touching patient 2: before cleaning/asepsis procedures 3: after body fluid exposure risk 4: after touching a patient 5: after touching patient surroundings

the chain of infection is made up of how many links...

6

Susceptible host

A person or animal that lacks the ability to fight infectious agent

Standard Precautions

A strict form of infection control that is based on the assumption that all blood and other body fluids are infectious. ex BSI

pathogen

An organism that causes disease

mode of transmission

Specific ways in which microorganisms travel from the reservoir to the suseptible host

Reservoir

The place where an infectious agent (microorganism) can survive.

portal of exit

a way for the infectious agent to escape from the reservoir in which it has been growing

a vector transmitted disease is spread by..

an animal

sources of infection can be...

an animal carrying a pathogen, unclean surfaces, someone carrying the bad pathogen

portal of entry

any body opening on an uninfected person that allows pathogens to enter

an example of a fungus is...

athletes foot

an example of a causative agent might be...

bacteria, pathogens, viruses

example of portal of entry

breaks in the skin, respiratory tract, digestive tract, mucous membrane, catheters/tubs/IV

you can break the chain by...

cleaning, sterilizing, disinfecting

to block the infectious agent you might...

cover your mouth when sneezing, wear gloves, wear masks

break the chain of infection- reservoir

dx and tx, quarantine, isolation, surveillance (containing the thing where infection lives)

example of medical asepsis

hand washing, PPE, basic hygiene, clean linens

breaking the chain of infection- portal of entry

hand washing, PPE, insect repellant, personal hygiene, wound care

breaking the chain of infection- portal of exit

hand washing, PPE, personal hygiene (things to keep the agent from leaving your body to another person ex coughing and sneezing you should wash your hands and wear a mask)

breaking the chain of infection- mode of transmission

hand washing, disinfectants, cleaning, sterilization, PPE, pest control, isolation, sneeze glass/barrier

the chain of infection deals with...

how a disease spreads

examples of reservoir

human body, environmental (soil), rodents, birds, water, equipment, food, water

Your body is a great place for pathogens to grow because...

it's warm, it has food, it has water

examples of direct contact

kissing, body lesions, physically touching

to stop the agent from entering the host you might...

maintain skin integrity, get all your immunizations, get proper nutrition and exercise

what link is broken when disinfecting door knobs and phones

mode of transmission, reservoir

what link is broken when administering a vaccine

new host/susceptible host

examples of portal of exit

open skin/wound, splatter of body fluid, aerosols (sneeze, coughs), urethra, vagina, rectum

Breaking the chain of infection- pathogen

pasteurization, chlorination, disinfectants (things that kill the infection in the first place)

select the correct order of the chain of infection model

pathogen, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host

PPE

personal protective equipment

medical asepsis

practices designed to reduce the number and transfer of pathogens; synonym for clean technique, sterilization

You can break the chain between the reservoir and the point of exit by...

using proper hygiene

breaking the chain of infection- susceptible host

vaccine/immunizations, continued tx of underlying conditions (diabetes, heart disease), insurance, healthy behavior

examples of pathogen

virus, bacteria, fungi, parasite

examples of susceptible host

young (5 or younger), elder population, immunosuppressed, anyone- depends on pathogen
