|
body temperature is
|
heat produce - heat loss= body temp
|
|
|
|
what is different from the core and surface temperatures?
|
the core temperature stays relatively constant with changes in the environment/activities
the surface temperature alters depending on blood flow to skin and the amount of heat lost to the environment |
|
|
|
temperature is aimed to measure the representative average of
|
core temperature
|
|
|
|
one factor that determines the clients temperature is
|
the site of temperature measurement
|
|
|
|
what principle does temperature follow?
|
homeostatic mechanisim
|
|
|
|
What is the first observable sign of illness?
|
an elevated temperature
|
|
|
|
what are the two terms used for high temperature?
|
pyrexia and fever
|
|
|
|
a constant body temperature continuously above 38C that demonstrates little fluctuation is called?
|
sustained temperature
|
|
|
|
fever is coming and going at intervals with normal temperature returns to normal value at least once in 24hrs
(fever spikes interspersed with usual temperature levels. temperature returns to acceptable value at least once in 24hrs) |
intermittent
|
|
|
|
fever spikes and falls without a return to normal temperature levels.
|
remittent
|
|
|
|
periods of febrile episodes mixed with acceptable temperature values. febrile episodes and periods of normothermia may be longer than 24 hours
|
relapsing
|
|
|
|
what are the core sites
|
rectum, tympanic membrane, esophagus,pulmonary artery, bladder
|
|
|
|
what are the surface sites
|
oral, skin, axilla -
|
these sites rely on effective circulation
|
|
|
why is oral a good temperature site
|
accesible
provides accurate surface temp reading |
|
|
|
why is axillary good?
|
safe
can be used in newborns .5 degrees less than oral 6-10 minutes |
|
|
|
why is rectal not good
|
dont use in new borns
preschoolers people with bowel/rectal disease .5 degrees greater than oral temp-core |
|
|
|
why is tympanic membrane good
|
ideal site/near hypothalamus and arteries
-core |
