Chapter 14 Flashcards
Preventing Infection
infection
disease from invasion / growth of microbes within the body
infection control
practice / procedures to prevent spread of infection
microorganisms
(microbe) small living organisms only viewable with microscope
pathogen
harmful microbes that cause infection
non-pathogens
microbes usually not a cause of infection
normal flora
microbes that normally live and grow in a certain area
antibiotics
drugs that kill bacteria
multidrug-resistant organism (MDRO)
microbe resistant to antibiotic
multidrug-resistant organism (MDRO) is caused by
when antibiotics are used when not needed or when antibiotic consumption is stopped before entire duration
colonization
infected person with pathogens but not displaying symptoms / signs
local infection
infection in a body part
systemic infection
infection of whole body
communicable / contagious disease
disease by pathogen that can be spread to others
pathway of infection:
1) source
2) reservoir
3) portal of exit
4) method of transmission
5) portal of entry
6) susceptible host
repeat
carrier
human / animal reservoir with no infection in the pathway process
healthcare-associated infection
(HAI) infection developed in person while in care
nonsocomial infection
infection from normal flora
asepsis
absence of disease-producing microbes
medical asepsis (cleaning techniques)
practices used to REDUCE number / spread of microbes
surgical asepsis (sterile technique)
practice used to REMOVE ALL microbes
sterile
absence of all microbes
contamination
process of becoming unclean
cross-contamination
passing microbes from one person to another with contaminated hands / equipment / supplies
hand-hygiene
prevent cross-contamination; soap and warm water / alcohol based hand-sanitizer
