ACTUAL Exam Questions and CORRECT
Answers
What are normal temperature ranges for full-term, preterm, and VLBW neonates? - CORRECT
ANSWER - -term: 36.5-37.5
-preterm: 36.3-36.9
-VLBW: 36.7-37.3


What are some physiologic reasons for temperature variation in neonates? - CORRECT
ANSWER - -little subcutaneous fat as insulation
-decreased amounts of brown fat and glycogen stores
-large body surface area-to-mass
-poor ability to vasoconstrict
-immature hypothalamus
-increased evaporative losses due to immature skin
-poorly developed shivering thermogenesis


What is the primary method for heat generation in neonates? - CORRECT ANSWER -
non-shivering thermogenesis: completed through the metabolism of brown fat


What are some common causes of hyperthermia in neonates? - CORRECT ANSWER --
maternal fever at delivery
-mechanical issues (not using servo mode, misplaced temperature probes, phototherapy lights)
-secondary to medications (i.e. prostaglandins)
-infection (mostly in term neonates)
