100

This type of heat loss occurs when moisture on the patient's skin turns into vapor.

Evaporation

100

The normal Neonatal Temperature range. 

 36.5°C-37.5°C

100

Preterm infants have longer _____ area compared to their body weight. 

Surface Area

100

This NICU device provides open access to the patient while delivering heat from above. 

Radiant Warmer

100

A patient's temperature is 36.1°C. This condition is called ____. 

Mild Hypothermia

200

Heat loss that occurs when a patient lies on a cold scale or mattress. 

Conduction

200

Temperature range considered mild hypothermia. 

36.0°C-36.4°C

200

The type of fat that helps newborns generate heat.

Brown Fat

200

This incubator setting automatically adjusts heat based on the patient's temperature. 

Servo Control

200

A patient under in Servo Mode is given heat via what mechanism.

Convection

300

Heat loss that occurs when air currents carry heat away from the patient.

Convection

300

Temperature that defines hyperthermia in a neonate. 

 ≥ 37.5°C

300

Preterm patients cannot effectively use this method of heat production. 

Shivering

300

This must be securely attached to the infant for Servo Mode to work properly. 

Bed-Continuous Skin Temperature Probe

300

A 26-week patient is delivered and immediately placed in polyethylene bag instead of being dried. This prevents this type of heat loss.  

Evaporation 

400

Heat loss that occurs when the patient transfers heat to nearby colder objects without touching them. 

Radiation

400

The environment where a patient maintains normal temperature with the lowest oxygen consumption. 

Neutral Thermal Environment

400

This organ is immature in preterm patients and contributes to poor temperature regulation. 

Hypothalamus 

400

This incubator feature reduces evaporative heat loss in extremely premature patients. 

Humidity

400

Cold stress increases oxygen consumption and can lead to this metabolic complication. 

Metabolic Acidosis

500

This mechanism accounts for the largest percentage of heat loss immediately after birth. 

Evaporation

500

The structure in the body responsible for temperature regulation in newborns. 

Hypothalamus

500

Because of temperature instability, cold stress increases consumption of these two things.

Oxygen and Glucose

500

If a temperature probe falls off while in Servo Mode, this dangerous outcome may occur. 

Hyperthermia (Overheating)

500

Late preterm patients often struggle to maintain temperature in this environment.
