Infection Control Flashcards
Asepsis
Absence of disease producing microorganisms
Sterility
Complete absence of all microorganisms
Sterilization
Complete destruction of all microorganisms
Pathogen
Microorganism capable of causing disease in humans
Nosocomial Infection
Infection acquired while in a hospital
Cross Contamination
Transmission of microorganisms between places or persons
Contamination
Presence of a microorganism in an otherwise sterile environment
Virulence
Heightened ability of an organism to produce infection in its host
Exotoxin
Poisonous substance produced primarily by gram + bacteria and secreted into surrounding media
some are extremely lethal
Endotoxin
Poisonous substance produced by gram- bacteria and released when the bacterial cell is destroyed
Vector
insect, animal or other carrier that transfers an infecting agent from one host to another
Disinfection
The process of destroying vegetative pathogenic microorganisms
Vegetative organisms
Growing microorganisms
Pathogenic organisms
Disease producing microorganisms
Contaminated
The introduction of disease-causing microorganisms
Static
Growth is inhibited
Spore
A resistant form of a certain species of bacteria
Exogenous
Originating or produced outside of the organism, tissue or cell
Endogenous
Originating or produced within an organism, tissue or cell
Direct Contact
Diseases
Hepatitis A
HIV
Staphylocccus
Enteric bacteria
Indirect Contact
Diseases
Pseudomonas aeruginosa
Enteric bacteria
Hepatitis B and C
HIV
Airborne diseases
Legionellosis Tuberculosis Varicella Measles Smallpox
OSHA mandates employers to offer these vaccinations
Hepatitis B Varicella Rubella Measles Pertussis
Respiratory care equipment that can spread pathogens
Nebulizers Bag-valve-mask devices Ventilator circuits Suction equipment Oxygen therapy Pulmonary function equipment
Diseases commonly associated with bronchoscopes
M. tuberculosis
nontuberculosis mycobacteria
Pseudomonas aeruginosa
Gram negative organisms
Pseuodmonas aeurginosa --> contact Haemophilus influenza --> droplet Serratia marcescens Escherichia coli --> contact Proteus klebsiella --> contact
Gram positive organisms
Staphylococcus A –> contact
Streptococcus Pneumoniae
Deplococcus
Pneumococcus
