features questions in areas like: patient care, med-surg, pharmacology, and
critical thinking. This study guide is perfect for ADN, BSN, and graduate
nursing students preparing for exams and clinical practice.
What is thermoregulation? ...... ANSWER ......body temperature
RATIONALE: body process that balances production and heat loss
heat produced - heat loss = body temperature
What is the goal of thermoregulation? ...... ANSWER ......to maintain
the body's temperature within acceptable/safe range
RATIONALE: the body wants to maintain homeostasis
body knows where it wants to live (temp. wise), doing what it can to get
back to homeostasis
to prevent death
too cold or too hot, death can occur
, What is homeostasis? ...... ANSWER ......Maintaining a stable
internal environment

What is cellular respiration? ...... ANSWER ......glucose and oxygen
make energy, with the by product of heat
RATIONALE: anything that we do to speed up this process, create more
heat
expend more energy, expend heat
In regards to body temperature, what happens to a body after a person
dies? ...... ANSWER ......body temp drops because no energy is being
created meaning no heat
What factors affect heat production? ...... ANSWER ......basal
metabolic rate, muscle activity, thyroxine output, sympathetic
stimulation/stress response, fever
What is basal metabolic rate? ...... ANSWER ......the rate of energy
utilization the body uses to maintain essential activities
RATIONALE: decreases with age: metabolism is slowing down
making older people colder
What does muscle activity (exercise) do to body temperature? ......
ANSWER ......when you exercise, you get hot
RATIONALE: exercise increases the need for energy (ATP), thus
produces byproduct of more heat
, shivering when cold, produces energy, producing more heat
What does thyroxine output do to body temperature? ...... ANSWER
Page | 3
......increased thyroxine levels release epinephrine, when it is released,
it increases vasoconstriction, we accelerated the cellular metabolic
rate, increasing the heat production
What is chemical thermogenesis? ...... ANSWER ......the stimulation
of heat production in the body through increased cellular metabolism
What is sympathetic stimulation/stress response do to body temperature?
...... ANSWER ......fight or flight response
RATIONALE: walking into exams, anxious or see a question that sends
you into fight or flight, you get a rush of heat through body
release of epinephrine and noro-epinephrine, which will increase
metabolism, creating more heat
What does a fever do to body temperature? ...... ANSWER ......an
immune response that raises the body temperature
RATIONALE: not will it raise body temperature, but increase our
metabolic needs/rate, increasing energy and thus our by product, heat
Wha are different types of heat loss from the body? ...... ANSWER
......radiation, conduction, convection, vaporization
, What is radiation? ...... ANSWER ......the transfer of heat from the
surface of an object without touching
RATIONALE: getting hot from the sun's rays (not touching)

dog doesn't touch, waking up sweating because the dog radiates so much
heat
What is conduction? ...... ANSWER ......transfer of heat from one
molecule to a molecule of lower temperature, needing to be touching
RATIONALE: tepid (cool) bath
-taking someone with a fever, putting them in a cool bath
ice packs
cool washcloths
heating pad
What is convection? ...... ANSWER ......dispersion of heat by the fluid
of air or water across the skin
RATIONALE: convection oven has a fan in the back, heat is being
dispersed through the fan
heat loss: fan
spritzing water
when dog is radiate heat, turn on fan to bring my body temperature down
fluid motion of air comes down and blows it away
amusement park with mist showers
