RNC-NIC THERMOREGULATION EXAM
QUESTIONS AND ANSWERS
What is the usual temperature range for full-term, preterm, and VLBW
neonates? - ANSWER: term (36.5-37.5), preterm (36.3-36.9), and VLBW
(36.7-37.3).
What are some physiological explanations for temperature variations in
neonates? - ANSWER: Little subcutaneous fat as insulation.
-lower levels of brown fat and glycogen reserves
-large body surface area-to-mass ratio
-Poor capacity to vasoconstrict
-Immature hypothalamus.
-Immature skin causes greater evaporative losses.
-Weakly developed shivering thermogenesis
What is the principal method of heat generating in neonates? - ANSWER Non-
shivering thermogenesis is completed through brown fat metabolism.
What are some typical causes of neonatal hyperthermia? - ANSWER: Maternal
fever at delivery.
-mechanical problems (not using servo mode, misplaced temperature probes,
phototherapy bulbs)
Secondary to drugs (e.g., prostaglandins)
