Chapter 15 - Infection control; prevent spread of disease in healthcare Flashcards
What is Aerobic?
A microorganism that requires oxygen to live
What is Anaerobic?
Organisms that reproduce with the absence of oxygen
What does the Pathogen need to survive?
Warm temperature areas (98.6F),
Dark areas,
& Moisture - in metabolism to carry away wastes
Example of a Virus
(can be multiple answers)
When one’s sickness spreads to the next
Example of an Infection - bacterial
(can be multiple answers)
When a small cut or open wound gets dirt or bacteria inside
Infectious Agent (germs)
-Chain of Infection
A pathogen, such as bacteria, virus, or parasite that causes disease
Reservoir (where germs live)
-Chain of Infection
An area where an infectious agent can live - humans, animals (pets or wild), environment, & food or water
Portal of Exit (how the germs get out)
-Chain of Infection
Way for infectious agent escapes reservoir (mouth, cuts, stool)
Transmission - spores (germs get around)
-Chain of Infection
Way for infectious agent to spread (through objects or bodily function) – Contact, Airborne, Droplet
Portal of Entry (how germs get in)
-Chain of Infection
Mouth, cuts in the skin, eyes can transmit bacterial infection to another
Susceptible Host (who?)
Anyone
-mostly babies, children, elderly, weakened immune systems, & unimmunized people (no vaccines)
What is Medical Asepsis?
Process of making an area clean & free of infectious materials ; clean techniques: reduces the number of microorganisms
Whats Infection process cycle?
continuous cycle pathogen must have to survive (w/o, pathogen dies)
Non-pathogens
microorganisms that don’t normally cause disease
Pathogens
disease-producing microorganisms
What is Nosocomial?
Disease spread through hospitals - hospital borne disease (ex. MRSA & ESBL)
Purpose of Standard & OSHA
Purpose of Standard MUST be followed by employees with occupational standards
OSHA - organization (federal) to enforce standard precautions in healthcare
(in any work setting)
What are Standard Precautions?
Rules (developed by CDC) to prevent spread of infection
Communicable disease
disease caused by pathogens that can be transmitted easily to others
Epidemic
Low spreads through local areas, regions (ex. hospitals)
Pandemic
Wide spreads through states, or world-wide
Herd Immunity
large amounts of people immune to a virus (stops spread of virus)
