LEC review: infection Flashcards
prevent spread of infection; implementing
procedures and policies
infection control
Microorganisms that invade body, immunity, and
Cause injuries or cause disease
Infection
3 types of infections
Microbes, Communicable infections, Nosocomial infections
investigation and control of various diseases
Especially if communicable and epidemic potential
the develop guidelines and recommends precautions
to protect people
CENTERS FOR DISEASE CONTROL AND PREVENTION (CDC)
received a vaccination against, or recovered from
infection that developed antibody against virus
immune
process is stopped at any component to prevent
infection
chain of infection
if pathogen enters host, chain is not yet completed
true or false
false
6 components of chain of infection
infectious agent, reservoir, exit pathway, means of transmission, entry pathway, susceptible host
a component of chain of infection which is a pathogenic microbe
infectious agent
a component of chain of infection that is considered as the source of infection
reservoir
a reservoir host is an animal/human infected
potential reservoirs are Person’s own flora and Contaminated articles & equipment
component of the chain wherein it is a way of agent to leave host
exit pathway
component of chain referring to the transfer from reservoir to individual
Means of transmission
There are 5 types: Airborne – evaporated droplet nuclei Contact – most frequent Droplet – mucous membrane of Mouth, nose, or conjunctive of ind. Vector – insect, arthropod, or animal Vehicle - food, water, or drugs
component of chain where agent enters host
entry pathway
component of the chain that is considered as those with decreased ability to resist infection
Factors: age, health, immune status
Susceptible host
PPE to be used in rooms of patients with airborne diseases
respirator
minimize spread; separate patients w/ transmissible disease
Isolation procedures
kind of isolation for highly susceptible to infections
protective/reverse isolation
established by CDC in 1985 when HCWs were reported to be infected with HIV through needlesticks
UNIVERSAL PRECAUTIONS
1 strategy for nosocomial infection control; combination of UP and BSI from both recognized and unrecognized sources
STANDARD PRECAUTIONS
safe handling of biologic substances
BIOSAFETY
Any material or substance harmful to health
BIOHAZARD
Exposure routes:
- Airborne: splashes, aerosols, or fumes
- Ingestion: neglect to sanitize hands before handling foods or covering the mouth w/ hands
- Nonintact skin: abrasions, burns,
cuts, scratches, sores, dermatitis, and chapped skin
- Percutaneous (through skin): accidental needle sticks, handling broken glass
- Permucosal (through mucous membranes)
3 bloodborne pathogen
HIV, HBV, HCV
