List |the |parts |of |the |chain |of |infection |(in |order): |- |correct |answer |- |infectious |agent
- |reservoir
- |portal |of |exit
- |mode |of |transmission
- |portal |of |entry
- |susceptible |host
infectious |agent |- |correct |answer |something |that |contains |bacteria, |fungi, |virus, |parasite(s), |or |
prion(s)
reservoir |- |correct |answer |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 |answer |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 |answer |how |a |bacteria, |virus, |fungus, |parasite, |or |prion |moves |
from |place |to |place
,contact |transmission |- |correct |answer |occurs |when |microorganisms |move |from |an |infected |
person |to |another |person
droplet |transmission |- |correct |answer |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 |answer |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 |answer |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 |answer |- |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 |answer |- |contact
- |droplet
- |airborne
- |vector
- |vehicle
vehicle |transmission |- |correct |answer |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 |answer |transmission |of |infectious |agents |through |animals, |such |
as |an |inset |or |rodent
examples: |mosquitoes |and |rats
Who |can |be |a |susceptible |host? |(4) |- |correct |answer |- |elderly
- |infants
- |immunocompromised
- |anyone
What |are |the |2 |types |of |contact |transmission? |- |correct |answer |- |direct
- |indirect
direct |contact |- |correct |answer |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 |answer |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 |answer |- |tuberculosis
- |rubeola |(measles)
- |varicella |(chickenpox)
List |2 |infections |spread |through |droplet |transmission: |- |correct |answer |- |influenza |virus
- |Bordetella |pertussis
What |type |of |transmission |is |the |following |an |example |of?
A |patient |has |a |draining, |infected |wound. |The |drainage |touches |a |cut |on |the |nurse's |skin, |
leading |to |infection. |- |correct |answer |direct |contact |transmission
What |type |of |transmission |is |the |following |an |example |of?
A |patient |who |has |a |respiratory |infection |sneezes |without |covering |the |mouth |and |nose. |A |
person |a |few |feet |away |becomes |infected |because |large |mucus |particles |land |in |their |mouth. |-
|correct |answer |droplet |transmission
What |type |of |transmission |is |the |following |an |example |of?
A |patient |who |coughed |in |their |hand |touches |a |door |handle. |Another |person |touches |the |
same |door |handle |and |becomes |infected |with |the |same |pathogen |as |the |patient. |- |correct |
answer |indirect |contact |transmission
What |type |of |transmission |is |the |following |an |example |of?
A |nurse |enters |a |room |where |a |patient |who |has |a |respirator |infection |was |present |for |several |
hours. |The |nurse |inhales |small |particles |that |remain |in |the |air |and |develops |an |infection. |- |
