Bacteria - CORRECT ANSWER-Microscopic organisms that are too small to be
visible to the naked eye. They are capable of causing infection when a person is
exposed to them under certain circumstances, such as through abraded skin (eg.
staphylococci, streptococci)
Bacterial Spores - CORRECT ANSWER-Some microorganisms are able to survive
in very harsh conditions by enveloping themselves with this thick wall. They make
bacteria highly resistant to killing. If they are introduced to the body where
conditions become more favorable—when there's more water or more food
available—the bacteria "come to life" again, transforming from a spore back to a
vegetative cell that can cause serious infection. They can be destroyed by
sterilization only
Blood borne infections - CORRECT ANSWER-Infections caused by viruses found
in the blood such as hepatitis B virus (HBV), hepatitis C virus (HCV), or human
immunodeficiency virus (HIV)
Acquired immune deficiency syndrome (AIDS) - CORRECT ANSWER-The last
stage of infection caused by the human immunodeficiency virus (HIV), which most
often results in severe damage to the body's immunse system
,Applicator - CORRECT ANSWER-A term referring to either single-use and
reusable spatula or similar devices
Antiseptic - CORRECT ANSWER-A chemical agent that destroys or inhibits
microorganisms on skin or tissue and has an effect of limiting optimally
preventing infection
Autoclave - CORRECT ANSWER-Equipment used for the sterilization of heat
resistant instruments
Body Fluids - CORRECT ANSWER-Fluids normally present in the body such as
blood, mucous, sweat, oil, saliva, urine, ooze from a festering sore, or tears. They
may contain infectious organisms.
Cleaning - CORRECT ANSWER-Refers to the process of removing blood, other
body fluids, organic material, tissue, and dirt from the surface of an object by
scrubbing with a brush, detergent and water. It greatly reduces the number of
microorganisms (including bacterial endospores) on items and is a crucial step in
processing. If items haven't first been cleaned, further processing might not be
effective.
Contamination - CORRECT ANSWER-A disinfected or sterile item or surface that
becomes soiled with microorganisms
, Cross-contamination - CORRECT ANSWER-The transfer of microorganisms from
one surface to another or from something contaminated to something clean or
sterile
Detergent - CORRECT ANSWER-A substance that enhances the cleaning action
of water (preferably warm/hot) or another liquid.
Disinfectant - CORRECT ANSWER-A chemical agent that destroys
microorganisms, but does not necessarily kill all microbial forms on inanimate
objects
Disinfection - CORRECT ANSWER-A process that destroys or kills some, but not
all, disease-producing microorganism on an object or surface. (Does not kill
spores)
Gloves - CORRECT ANSWER-Protective equipment that must be worn to protect
against exposure to blood and other potentially infectious materials. Disposable
gloves are single use that are disposed after each use. Most popular are made
from latex, but hypo-allergenic gloves, glove liners, powder less gloves, or other
alternatives are available for those allergic,
Hepatitis B virus (HBV) - CORRECT ANSWER-Infection of the liver, can cause a
life long infection, cirrhosis (scarring), cancer, liver failure, death. Takes 6 weeks
to 6 months to produce infection when the virus enters the body
