HCB Test 2 Exam Questions and Verified
Detailed Answers | Graded A+
What's does infection control involve? - ✔✔taking steps to prevent the spread
of infectious agents
Antibacterial - ✔✔directed or effective against bacteria (KILLS)
antiseptic - ✔✔preventing or arresting the growth of microorganisms
Asepsis - ✔✔the condition of being aseptic (absence of pathogens growing)
aseptic technique - ✔✔preventing infection (reduces the risk of infection)
Bacteria - ✔✔single cell microorganism that multiplies rapidly
blood-borne pathogen - ✔✔A specific causative agent of disease located in the
blood (HIV or hepatitis)
contagious disease - ✔✔infectious disease that is spread through contact with
one who has it, with bodily discharge or an object touched by that person
contaminated - ✔✔to soil, stain, or infect by contact or association (presence of
blood or other material that is infectious or potentially infectious)
direct contact - ✔✔union of body surfaces
disinfectant - ✔✔free from infection (kills agent but not spores)

,disinfection - ✔✔process that eliminates agent but not spores
fungi - ✔✔kingdom of parasitic spore-producing eukaryotic that lacks
chlorophyll (molds, rust, mildew)
Health care-associated infections (HAIs) - ✔✔Nosocomial infection that occurs
in a hospital, happens within 72 hours of being admitted, mostly due to lack of
care
infection - ✔✔infective agent contaminated with an infective agent
isolation - ✔✔separation for a period of time to prevent or limit transmission of
infectious agent
microorganism - ✔✔organism of microscopic or ultramicroscopic size
pathogen - ✔✔disease or virus that produces infection
Standard Precautions - ✔✔group of infection prevention that applies to all
patients
Infection Control Concepts - ✔✔standard precautions are concepts in which all
body fluids are assumed to be infected with blood-borne pathogens
chain of infection - ✔✔sequence of events that must occur to develop an
infection
Infectious Agent (pathogen) - ✔✔disease causing microorganism

, What are the common types of infectious agents? - ✔✔bacteria, viruses,
protozoa, fungi, and helminths
bacteria - ✔✔multiply rapidly, can transmit to each other
viruses - ✔✔DNA or RNA encased in protein, cannot reproduce outside of a
living host cell
protozoa - ✔✔unicellular microorganisms that infect the blood, brain, etc
helminths - ✔✔parasitic worms
reservoir - ✔✔the place where pathogens grow, could or could not multiply
portal of exit - ✔✔a route for pathogens to leave the host
mode of transmission - ✔✔the way the infectious agent moves to another
source
what is the most frequent source of HAIs? - ✔✔contact
what are the two types of contact? - ✔✔direct and indirect
direct contact - ✔✔person to person or source to host
indirect contact - ✔✔Contact with contaminated inanimate objects
vector transmission - ✔✔through a bite
droplet infection - ✔✔through droplets from an infected person when projected
a short distance
