  a. 24 to 27 C (75.2 to 80.6 F)
  b. 28 to 31.5 C (82.4 to 88.7 F)
  c. 32 to 33.5 C (89.6 to 92.3 F)

Answer to Question 1

ANS: B
Preterm infants are at greater risk to develop cold stress because of thin skin, decreased subcutaneous fat, and poor muscle tone.

Answer to Question 2

ANS: C
A neutral thermal environment is one in which the infant can maintain a stable body temperature with minimal oxygen need and without an increase in metabolic rate. The range of environmental temperature that allows this stability is called the thermoneutral zone. In healthy, unclothed, full-term newborns, an environmental temperature of 32 to 33.5 C (89.6 to 92.3 F) provides a thermoneutral zone. When the infant is dressed, the thermoneutral range is 24 to 27 C (75.2 to 80.6 F).
