NSG 170 Thermoregulation Test
Questions and Correct Answers
Thermoregulation ✅balances heat production, heat loss to maintain body's
temperature
1. Surface temperature fluctuates in response to environmental factors
B. Core temperature more reliable; relatively constant 37°c, or 98.6°f
Afebrile ✅absence of a fever
Basal metabolic rate (bmr) ✅the amount of energy expended by the body at rest
Brown adipose tissue (bat) ✅brown fat found in newborns that helps protect their
organs from extreme temperature changes
Chemical thermogenesis ✅the stimulation of heat production in th ebody through
increased cellular metabolism
Conduction ✅the process of heat transfer through physical contact of one surface with
another surface
Convection ✅the process of heat transfer through the fluid motion of air or water
across the skin
Evaporation ✅the process of converting water to a vapor
Febrile ✅presence of a fever
Fever ✅a protective immune response to foreign antigens within the body that causes
an increase in the cellular metabolic rate that further increases the body's temperature
Heat balance ✅the amount of heat produced by the body equals the amount of heat
lost, and the individual's body temperature remains within the normal range
Heat transfer ✅movement of heat from one place or object to another
Hyperthermia ✅the body produces more heat than is lost
(fever) temperature over 38ºc (100.4ºf)
1. Heat exhaustion
2. Heat stroke
, Hypothermia ✅more heat is lost than is produced
Core temperature below 36ºc (96.8ºf)
1. Excessive heat loss
2. Inadequate heat production to counteract heat loss
3. Impaired hypothalamic thermoregulation
Malignant hyperthermia ✅a potentially fatal, inherited disorder that results from the
body's reaction to inhalation of volatile anesthetic gases and succinylcholine
Neutral thermal environment (nte) ✅an incubator-environment temperature similar to
that of a newborn's body temperature designed to minimize thermal body stress
Normothermia ✅usual range of core body temperature
Usual core body temperature range 36 and 38.5°c (96.8 and 101.3°f)
Radiation ✅the process of heat transfer with no physical contact
Types of heat transfer ✅a. Conduction transfer of heat from one molecule to a
molecule of lower temperature
B. Convection dispersion of heat by air currents
C. Radiation transfer of heat from surface of one object to surface of another
D. Evaporation continuous evaporation of moisture from respiratory tract, mucosa of
mouth, skin
Regulatory system has 3 components ✅1. Sensors detect heat send signals to effector
system to decrease heat production, increase heat loss
2. Sensors detect cold send signals to effector system to increase heat production,
decrease heat loss
3. Hypothalamus controls core temperature
Three physiologic responses to cold ✅i. Shivering increases heat production
Ii. Sweating inhibited to decrease loss
Iii. Vasoconstriction decreases heat loss
