Asepsis and Infection Control Flashcards
Infection
Condition in which the body is invaded by microorganisms that can produce injurious effects
Resident (normal) Flora
Microorganisms that are always present without altering the client’s health
Transient Flora
Microorganisms that are episodic (of limited duration)
Pathogen
Disease-producing microorganisms
Pathogenicity
Ability of microorganisms to produce disease
Virulence
Frequency with which a pathogen causes disease
Infectious Agent
Microorganism that causes cellular injury
Communicable Agent
Infectious agent transmitted to a client by direct or indirect contact, through a vehicle or vector or an airborne route.
Generalized Infection
Vague - may include headache, malaise, muscle aches, fever, anorexia. whole body involvement
Septicemia
Microorganisms are present and multiplying in the blood
Reservior
Where infectious agents live, multiply, and reproduce in order to be transmitted to a susceptible host.
Portal of Exit
Route by which the infectious agent leaves the reservoir or source host. May be the same as the Portal of entry.
Mode of transmission
How the pathogen moves from one location to another
Contact
two - direct and indirect
Direct Contact
person to person
Indirect
spreading of organisms by contact with contaminated objects
Airborne
Spreading of infectious material in dust particles or evaporated droplets that can stay suspended in air for long periods of time.
Droplet
Occurs during talking, sneezing, suctioning.
Common Vehicle
Agent transferred by contaminated inanimate objects like water food milk drugs and blood.
Vector-Borne
Transfer of microorganisms from infected animal carriers
Portal of Entry
Includes the respiratory tract, skin, mucous membranes, GI tract, genitourinary tract, and placenta.
Susceptible Host
Factors that contribute to people being susceptible:
very young
old age
mal-nourishment
being immunocompromised
having a chronic disease
being under stress
undergoing an invasive procedure
compromised skin integrity
