HCB TEST 2 Exam Actual Questions and
Answer
Antibacterial-
Directed or effective against bacteria.
Antiseptic-
preventing or arresting the growth of microorganisms.
Asepsis-
The condition of being aseptic
Aseptic technique-
preventing infection - clean technique
Bacteria-
(Plural bacterium) any of a domain pf prokaryotic round, spiral, or rod shaped single-celled
microorganisms that may lack cell walls or are gram-positive or gram-negative, typically live in
soil, water, organic matter, or the bodies of plants and animals.
Blood-born Pathogen-
Pathogen- a specific causative agent (as a bacterium or virus) of disease located in the blood.
Contagious Disease (Communicable Disease)-
communicable by contact with one who has it, with a bodily discharge of such a patient, or with
an object touched by the patient.
Contaminated-
to soil, stain, or infect by contact or association
Direct Contact-
union or junction of body surfaces
Disinfectant-
to free from infection especially by destroying harmful microorganisms. (Products)
Disinfection-
to free from infection especially by destroying harm microorganisms. (Action)
Fungi-
,any of the kingdom Fungi of saprophytic and parasitic spore- producing eukaryotic typically
filamentous organisms formerly classified as plants that lack chlorophyll and include molds, rust,
mildews, smuts, mushrooms, and yeasts
Health Care Associated Infections- HAIS,
also known as a Nosocomial infection; acquired or occurring in a hospital.
Infection-
infective agent or material contaminated with an infective agent
Isolation-
A separation for the period of communicability of infected people or animals from others, so as
to prevent or limit the direct or indirect transmission of the infectious agent from those who are
infected to those who are susceptible
Microorganism-
an organism of microscopic or ultramicroscopic size.
Pathogen
-a disease producing microorganisms
Standard precautions
A group of infection prevention practices that apply to all patients, regardless of suspected or
confirmed diagnosis or presumed infection status.
Infection control concepts
Infection control concepts Standard precautions are concepts in which all body fluids are
assumed to be infected with blood-borne pathogens.
Chain of infection:
A sequence of circumstances where all events must occur to develop an infection
#1 of Chain of infection
Infectious Agent
Infectious Agent (pathogen)
disease causing microorganism
Bacteria
Single cell microorganism that multiply rapidly
Viruses
DNA or RNA is encased in a protein coating. Cannot reproduce outside of a living host cell.
, Protozoa
Unicellular microorganism that can infect the blood, brain, intestines and other body areas
Fungi
Tiny, primitive organisms that contain no chlorophyll
Helminthes are
parasitic worms or flukes
2nd chain of infection
reservoir
reservoir
A place where the pathogen grows and reproduces
3rd chain of infection
portal of exit
portal of exit
An exit route for pathogens to leave its host
4th chain of infection
mode of transmission
mode of transmission
The manner in which an infectious agent moves from one source to another
HAIs
hospital acquired infections
direct contact
person to person physical contact between source and susceptible host
indirect contact
Involves contact with contaminated inanimate objects
vector transmission
occurs through a bite
Droplet infection
occurs when the droplets from an infected person are projected a short distance to the host's nasal
mucosa, mouth or conjunctiva
airborne transmission
Occurs when infectious particles dispersed in the air enter the host by inhalation
