,List the parts of the chain of infection (in order): - correct ans:- infectious agent
- reservoir
- portal of exit
- mode of transmission
- portal of entry
- susceptible host
infectious agent - correct ans:something that contains bacteria, fungi, virus, parasite(s), or prion(s)
reservoir - correct ans:the habitat of the infectious agent and is where it lives, grows, and reproduces
itself or replicates
animate examples: people, insects, birds, animals
inanimate examples: contaminated soil, water, food, medical equipment, IV fluids, feces
portal of exit - correct ans:the means by which the infectious agent can leave the reservoir
examples: any body orifice (ears, nose, or mouth), the skin, or blood or body fluids that leave the body
through coughing, sneezing, etc.
mode of transmission - correct ans:how a bacteria, virus, fungus, parasite, or prion moves from place to
place
contact transmission - correct ans:occurs when microorganisms move from an infected person to
another person
droplet transmission - correct ans:occurs when airborne droplets from the respiratory tract of a client
travel through the air and into the mucosa of a host
,can be from sneezing, coughing, singing, and talking
medical procedures like CPR and intubation can release droplets into the air
airborne transmission - correct ans:occurs when small particulates move into the airspace of another
person and carry infectious agents
these patients should be placed in a private room with negative air pressure (circulates the air outside of
the building)
portal of entry - correct ans:provides a place for an infectious agent to enter the individual so it can
replicate or its toxin can act
examples: any body orifice or the skin
List factors that increase host susceptibility (8): - correct ans:- age
- underlying disease (like HIV/AIDS)
- malignancy
- transplants
- medications (like immunosuppressants, antirejection meds, etc.)
- surgical procedures
- radiation therapy
- indwelling devices (like urinary catheters, central lines, etc.)
List the modes of transmission (5): - correct ans:- contact
- droplet
- airborne
- vector
- vehicle
, vehicle transmission - correct ans:transmission of infectious agents to multiple individuals through a
common source, such as contaminated food or water
example: food contaminated with e. coli
vector transmission - correct ans:transmission of infectious agents through animals, such as an inset or
rodent
examples: mosquitoes and rats
Who can be a susceptible host? (4) - correct ans:- elderly
- infants
- immunocompromised
- anyone
What are the 2 types of contact transmission? - correct ans:- direct
- indirect
direct contact - correct ans:transmission occurs when microorganisms are directly moved from the
infected person to another person without having a contaminated object or person between the 2
indirect contact - correct ans:transmission occurs when microorganisms are moved from the infected
person to another person with a contaminated object or person between the 2
List infections caused by airborne transmission (3): - correct ans:- tuberculosis
- rubeola (measles)
- varicella (chickenpox)
List 2 infections spread through droplet transmission: - correct ans:- influenza virus
