Test 2- Ch. 6 Contnuing Care of the Neonate

Question 1

Thermoregulation can best be defined as the maintenance between

Answer 1

heat dissipation and heat production by the body

Question 2

What is the thermoneutral zone

Answer 2

the temp range in which the metabolic rate is at a minimum and thus, oxygen consumption is at its lowest

Question 3

Internal thermal gradient (ITG) is the temp difference between the

Answer 3

warm body core and the cooler skin

Question 4

What is the ITG regulated by?

Answer 4

• metabolic rate
• the amount of subcutaneous fat present
• the amount of surface area available for dissipation of heat
• the distance from the body core to skin surface

Question 5

The temp difference between the skin and the environment is called

Answer 5

External thermal gardient (ETG)
