|
what is the acceptable temperature for humans |
96.8-100.4F, 36-38C |
|
|
Average temp for elderly |
96.8f |
|
|
does the core temp. change or remain the same |
same |
|
|
does the surface temperature change or remain the same |
change |
|
|
thermoregulation |
regulation of body temperature, done by balancing heat loss and heat produced. |
|
|
hypothalamus
|
body's thermostat. responsible for controlling the bodys temperature. sends messages to blood vessels to help conserve heat by vasoconstriction or to release heat by vasodilation and sweating. shivering is an involuntary response to create heat. muscular activity increases heat production in the body |
|
|
basal metabolic rate |
heat produced by the body at absolute rest, is affected by thyroid hormones that control metabolism. men have higher BMR than women |
|
|
Heat Loss |
lost from the skin surface by radiation, conduction, evaporation, convection, diaphoresis |
|
|
how does age influence temperature |
infants and children until puberty have an unstable control mechanisms that are immature or impaired. older adults are sensitive to extremes since their control mechanisms may deteriorate |
|
|
how does exercise influence temperature |
muscle activity increases metabolism |
|
|
how does the hormone level influence temperature |
primarily affects women due to hormonal changes in cycle |
|
|
how does stress influence temperature |
physical and emotional stress changes phsyiology and increases temperature through hormone and nervous stimulation |
|
|
how does the environment influence temperature |
cold or extreme heat may affect temp/. |
|
|
when is temp the lowest |
1-4am |
|
|
when is temp the highest
|
6pm |
|
|
how long does temp take to change with a change of work and sleeping patterns |
1-3weeks |
|
|
core body temperature sites |
rectal, tympanic, pulmonary, urinary bladder, esophagus |
|
|
surface body temperature sites |
oral, skin, axillae |
|
|
how much higher or lower is rectal temp compared to oral |
1 degree higher |
|
|
how much higher or lower is an axillary temp compared to oral |
1 degree lower |
|
|
is a fever dangerous at 102 |
no |
|
|
is a fever dangerous about 102 |
yes |
|
|
diaphoretic |
heart exhaustion. excessive perspiration leads to fluid and electrolyte imbalances move client to cooler environment and replace fluids can lead to heartstoke if not treated |
|
|
heartstoke |
emergency situation caused by prolonged exposure to sun or heat. hypothalamus malfunctions and does not induce sweating. symptoms include cramps, confusion, visual disturbances, and hot, dry skin. cool client and replace fluids with IV |
|
|
what happens at 105 |
body starts to cook. Brain is the first thing to go |
|
|
when do vital signs fail for hypothermia? |
94 |
|
|
how do you treat hypothermia |
SLOWLY increase the temp with blankets, warming devices, and warm fluids |
