NUR170 EXAM 4 2026 ACTUAL SCRIPT
COMPLETE QUESTIONS AND ANSWERS 100%
CORRECT
◉ Reservoir. Answer: Where the bug likes to live
The natural habitat of the organism that promotes growth and
multiplication
Humans
We are warm, moist and full of food
Ex. HIV
Animals
Ex. Rabies
Soil
Ex. Gangrene, tetanus
Food
Water
Ex. Legionnaires disease
Dairy
Ex. Listeria. Seen a lot in the Amish and with people who do not
pasteurize their dairy
Inanimate objects
Ex. Flu, C. Diff
,◉ Portal of Exit. Answer: They all want to take over the world and
have to exit the host to do that
The point of escape for the organism from the reservoir
Respiratory
GI/GU
Blood
◉ Means of Transmission. Answer: Contact
Airborne
Droplet
Vectors
◉ Contact means of transmission. Answer: Direct contact- When the
bacteria/virus goes directly from contact to the body
Indirect contact- When the bacteria/virus goes onto something
other than the human body and then to a human body after a person
touches it
Ingestion- Gets into your GI tract
◉ Droplet means of transmission. Answer: When the bacteria/virus
is when you sneeze and the droplets from your sneeze carry the
bacteria/virus
,Most common bug transmitted this way is influenza
◉ Airborne means of Transmission. Answer: When the
bacteria/virus lives in the air and you inhale it
Ex. TB
◉ Vectors. Answer: Nonhuman carriers that transmit organisms by
injecting salivary fluid
Ex. Ticks that carry Lyme disease
Mosquitos that carry Ebola
Dogs that carry rabies
◉ Portals of Entry. Answer: Point at which organisms enter the new
host
Usually the same as the portal of exit
So if they sneezed it comes out their mouth and will usually be
entered through the mouth
◉ Susceptible Host. Answer: Host has to be susceptible to the
pathogen to get infected
Susceptibility- The degree of resistance of the potential host of to the
pathogen
Integrity of skin and mucous membranes is your best defense
Keep these intact
, pH levels
If it is out of whack it can make us more susceptible
Age, sex, race
All change susceptibility to different pathogens
Immunizations
Stress/Fatigue
The more stressed you are the more susceptible to disease
Invasive/indwelling devices
Pull them out as soon as you can
Health habits
Nutrition/ water
Exercise
◉ Infectious Process. Answer: Incubation phase
Prodromal phase
Full stage of illness
Convalescent period
◉ Incubation phase. Answer: The time between when the bug enters
the body and when symptoms start to appear
The length depends on the bug but can be days to weeks
