2025 QUESTIONS AND ANSWERS
Acquired immune deficiency syndrome (AIDS) - ANS 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 - ANS A term referring to either single-use and reusable spatula or similar devices
Antiseptic - ANS A chemical agent that destroys or inhibits microorganisms on skin or tissue
and has an effect of limiting optimally preventing infection
Autoclave - ANS Equipment used for the sterilization of heat resistant instruments
Bacteria - ANS 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 - ANS 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 - ANS Infections caused by viruses found in the blood such as
hepatitis B virus (HBV), hepatitis C virus (HCV), or human immunodeficiency virus (HIV)
Body Fluids - ANS 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 - ANS 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 - ANS A disinfected or sterile item or surface that becomes soiled with
microorganisms
Cross-contamination - ANS The transfer of microorganisms from one surface to another or
from something contaminated to something clean or sterile
Detergent - ANS A substance that enhances the cleaning action of water (preferably
warm/hot) or another liquid.
Disinfectant - ANS A chemical agent that destroys microorganisms, but does not necessarily
kill all microbial forms on inanimate objects
Disinfection - ANS A process that destroys or kills some, but not all, disease-producing
microorganism on an object or surface. (Does not kill spores)
Gloves - ANS 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,
