Chapter 5 Flashcards
Infection prevention
set of methods to prevent and control the spread of disease
microorganism
living thing that is so small it is only visible under a microscope
microbe
another name for microorganism
infections offur when
harmful microorganisms (pathogens) invade the body and multiply
localized infection
infection that is limited to a specific location in the body, symptoms/signs include: pain, redness, swelling, pus, drainage, heat)
systemic infection
affects the entire body and travels throughout the bloodstream and is spread throughout the body Symptoms/signs include: fever, body aches, chills, nausea, vomiting, weakness, headache, mental confusion, drop in normal blood pressure)
what are the five parts in the chain of infection
causative agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host
causative agent
pathogen microorganism that causes disease (bacteria, viruses, fungi and parasites)
reservoir
pathogens lives and multiples and is found in warm, dark, and moist places
portal of exit
any body opening on an infected person that allows pathogens to leave (eyes, nose, mouth or cut)
mode of transmission
pathogen travels through direct contact (touching the infected person/secretions) or indirect contact (touching an object contaminated by infected person such as a needle, dressing, tissue or bedlinen)
portal of entry
body opening on an uninfected person that allows pathogens to enter
susceptible host
uninfected person who could become ill
medical asepsis
measurees used to reduce and prevewnt the spread of pathogens
surgical asepsis
makes an object or area completely free of all microorganisms not just pathogens
Occupational Safety and Health Administration (OSHA)
federal gov agency that makes rules to protect workers from hazards on the job
Centers for disease control and prevention (CDC)
federal gov agency that issues guidelines to protect and improve the health of individuals and communities
standard precautions
treat blood, body fluids, nonintact skin (sores, abrasions, pimples) and mucous membranes, body fluids (tears, saliva, sputum, urine, feces, semen, vaginal secretions, wound drainage and vomit) as infected. Sweat does not count
what are the guidlines in standard precautions
wash hands before putting on gloves, wear gloves if coming in contact, remove gloves when finished, wear a gown, use caution
antimicrobial agent
destroys, resists, and prevents the development of pathogens
multidrug-resistant organisims (MDRO)
microorganisms that are resistant to one or more antimicrobial agent that are commonly used for treatments such as scabies, lice, influenza
bloodborne pathogens
microorganisms found in human blood that can cause infection and disease in humans and can be found in body fluids, draining wounds, mucous membranes.
HIV
human immunodeficiency virus and can cause aids
Hepatitis
inflamation of the liver, Hep A is result of fecal-oral contamination, Hep B bloodborne disease
