Unit 3 Flashcards
Aerobic bacteria
microorganisms that require oxygen to live
Anaerobic bacteria
microorganisms that exist without oxygen
Antimicrobial agents
are chemicals that destroy or suppress the growth of infectious microorganisms
Antiseptics
chemicals such as alcohol that inhibit the growth of, but do not kill, microorganisms
Asepsis
practices that decrease or eliminate infectious agents, their reservoirs, and vehicles for transmission
aseptic techniques
measures that reduce or eliminate microorganisms
biologic defense mechanisms
anatomic or physiologic methods that stop microorganisms from causing an infectious disorder
broad-spectrum antibiotics
those prescribed to eliminate a wide range of bacteria
Carriers
asymptomatic clients or animals who harbor pathogens but do not show evidence of an infectious disease
chain of infection
the sequence that enables the spread of disease-producing microorganisms
communicable diseases
diseases that can be transmitted to other people
Community-acquired infections
infections that are not present or incubating prior to care provided by health care
Concurrent disinfection
measures that keep the client environment clean on a daily basis
Contagious diseases
diseases that can spread rapidly among individuals in close proximity to each other
Disinfectants
chemicals that destroy active microorganisms but not spores
exit route
is how microorganisms escape from the original reservoir
fomites.
Nonliving reservoirs are called…
Hand antisepsis
means the removal and destruction of transient microorganisms without soap and water. It involves products such as alcohol-based liquids, thick gels, and foams
Hand hygiene
refers to removing surface contaminants on the skin by either hand washing or hand antisepsis
Hand washing
is a medical aseptic practice that involves cleaning the hands with soap, water, and friction to mechanically remove dirt and organic substances
health care–associated infections
infections acquired while a person is receiving care in a health care agency
means of transmission
is how infectious microorganisms move to other locations.
contact, droplet, airborne, vehicle, and vector
Medical asepsis
practices that confine or reduce the numbers of microorganisms
Microorganisms
living animals or plants visible only through a microscope, are commonly called “microbes” or “germs
