Asepsis and Infection Control

STUDY
PLAY
Aerobic
requires oxygen to live and grow
Anaerobic
can live without oxygen
Antibody
immunoglobulin produced in response to a specific antigen
Antimicrobial
antibacterial agent that kills bacteria/suppresses their growth
Asepsis
using methods to prevent infection
Bacteria
the most significant and most commonly observed infection-causing agent
Disinfection
process used to destroy microorganisms; destroys all pathogentic organisms except spores
Endemic
something that occurs with predictability in one specific region/population
Endogenous
infection in which the causative organism comes from microbial life the person himself/herself harbors
Exogenous
infection in which the causative organism is acquired from outside the host
Fungi
plant-like organisms (molds & yeasts) that can cause infection
Heath-care associated infection (HAI)
an infection that was not present on admission to the hospital and develops during the course of treatment for other conditions
Host
animal or person on or within which organisms live
Iatrogenic infection
infection that occurs as a result of a treatment/diagnostic procedure
Infection
disease state resulting from pathogens in or on the body
Isolation
protective procedure designed to prevent the transmission of specific microorganisms
Medical Asepsis
practices designed to reduce the number and transfer of pathogens
Nosocomial
something originating or taking place in the hospital
Pathogen
disease-producing microorganism
Personal-Protective equipment (PPE)
gloves, gowns, masks, and protective eye gear designed to minimize/prevent the heath-care worker's exposure to infectious material
Reservoir
natural habitat for the growth and multiplication of microorganisms
Standard Precautions
CDC precautions used in the care of all patients regardless of their diagnosis/possible infection status
Sterilization
(1) the process by which all microorganisms including spores are destroyed (2) surgical procedure performance to render a person infertile
Surgical Asepsis
practices that render and keep objects and areas free from microorganisms
Transmission-Based Precautions
CDC precautions used in patients known/suspected to be infected with pathogens that can be transmitted by airborne, droplet, or contact routes
Vector
nonhuman carriers, such as mosquitoes, ticks, and lice, that transmit organisms from one host to another
Virulence
ability to produce disease
Virus
smallest of all microorganisms
