Question 1

What is the normal axillary temperature range for a healthy term newborn?

Accepted Answer

97.7–99.5°F (36.5–37.5°C)

Answer

Normal axillary temperature for a term newborn is 97.7–99.5°F (36.5–37.5°C); values outside this range require further assessment.

Question 2

Which mechanism of heat loss is responsible for a newborn losing heat to a cold incubator wall without direct contact?

Accepted Answer

Radiation

Answer

Radiation is the transfer of heat from the newborn's body to cooler surrounding surfaces without direct contact.

Question 3

What is the primary reason newborns are at high risk for heat loss immediately after birth?

Accepted Answer

Large body surface area relative to body mass and limited subcutaneous fat

Answer

Newborns have a large surface area-to-mass ratio and minimal subcutaneous fat, making them highly susceptible to heat loss.

Question 4

Which immediate nursing action best prevents heat loss by evaporation in the delivery room?

Accepted Answer

Thoroughly drying the newborn and removing wet linens

Answer

Drying the newborn immediately and replacing wet linens removes the primary source of evaporative heat loss after birth.

Question 5

What is the neutral thermal environment (NTE) for a newborn?

Accepted Answer

The environmental temperature at which the newborn maintains normal body temperature with minimal metabolic effort

Answer

The neutral thermal environment is the environmental temperature range at which a newborn maintains normal body temperature with minimal oxygen and caloric expenditure.
