Indection Control - Chapter 17 Flashcards
Asepsis
Freedom from infection
Bacteria
Prokaryotic, ubiquitous, single-celled organisms
Bloodborne Pathogens
Disease-causing microorganisms that may be present in human blood.
Chemotherapy
Treatment of disease by chemical agents.
Cyst
Stage in the life cycle of certain parasites during which they are enclosed in a protective wall.
Dimorphic
Occurring in two distinct forms.
Diseases
Deviations from or interruptions of the normal structure or function of any part, organ, or system (or combination thereof) of the body that are exhibited by a characteristic of symptoms and signs and whose cause, pathologic mechanism, and prognosis may be known or unknown.
Disinfectants
Chemicals used to free an environment from pathogenic organisms or to render such organisms inert, especially as applied to the treatment of inanimate materials to reduce or eliminate infectious organisms.
Eukaryotes
Organisms whose cells have a true nucleus.
Flora
Microbial community found on or in a healthy person.
Fomite
Object, such as a book, wooden object, or article of clothing, that is not itself harmful but is able to harbor pathogenic micro organisms and thus may serve as an agent of transmission of an infection.
Fungi
General term used to denote a group of eukaryotic protists- including mushrooms, yeasts, rusts, mold, and smuts- that are characterized by the absence of chlorophyll and by the presence of a rigid cell wall.
Healthcare Associated Infection (HAI)
Infection that patients acquire while they are receiving treatment for another health care issue.
Host
Animal or plant that harbors or nourishes another organism.
Iatrogenic
Resulting from the activities of physicians.
Immunity
Security against a particular disease.
Infection
Invasion and multiplication of micro organisms in body tissues that may be clinically inapparent or may result in local cellular injury as a result of competitive metabolism, toxins, intracellular replications, or antigen-antibody response.
Medical Asepsis
Reduction in numbers of infectious agents, which, in turn, decreases the probability of infection but does not necessarily reduce it to zero.
Nosocomial
Pertaining to or originating in the hospital; said of an infection not present or incubating before admittance to the hospital but generally developing 72 hours after admittance.
Pathogens
Disease spreading organisms.
Prokaryotes
Cellular organisms that lack a true nucleus.
Reservoir
Alternative or passive host or carrier that harbors pathogenic organisms, without injury to self, and serves as a source from which other individuals can be infected.
Standard Precautions
Precautions to prevent the transmission of disease by body fluids and substances.
Sterilization
Complete destruction or elimination of all living microorganisms, accompanied by physical methods (dry or moist heat), chemical agents (ethylene oxide, formaldehyde, alcohol), radiation (UV, cathode), or mechanical method (filtration).
