- What is the normal axillary temperature range for a neonate?
Show answer
36.5 to 37.5 degrees C (97.7 to 99.5 F)- What is the primary mechanism of heat loss in a newly born infant who is wet?
Show answer
Evaporation- What type of fat do neonates use to generate heat without shivering?
Show answer
Brown adipose tissue (brown fat)- Why are preterm infants especially prone to heat loss?
Show answer
They have less subcutaneous fat, thinner skin, and a larger surface area to body weight ratio- What NICU equipment is used to maintain a neutral thermal environment for an unstable newborn?
Show answer
A radiant warmer or incubator- What is the goal of a neutral thermal environment?
Show answer
To maintain normal body temperature with the lowest possible oxygen consumption and caloric expenditure- Convective heat loss in the NICU occurs through what mechanism?
Show answer
Loss of heat to cooler surrounding air currents, such as drafts- Conductive heat loss occurs when an infant is placed on what type of surface?
Show answer
A cold surface that is in direct contact with the infant's skin- Radiant heat loss occurs when heat transfers from the infant to what?
Show answer
Nearby cooler solid objects not in direct contact, such as the walls of an incubator- What early sign of cold stress might a nurse observe in a neonate?
Show answer
Increased respiratory rate and irritability, then lethargy and poor feeding- Cold stress increases a neonate's risk for what metabolic complication?
Show answer
Hypoglycemia- What respiratory support device delivers continuous distending pressure without intubation?
Show answer
CPAP (continuous positive airway pressure)- What is surfactant used to treat in premature infants?
Show answer
Respiratory distress syndrome (RDS)- How is exogenous surfactant typically administered?
Show answer
Instilled directly into the trachea via an endotracheal tube or thin catheter- What chronic lung condition can result from prolonged mechanical ventilation and oxygen exposure in preterm infants?
Show answer
Bronchopulmonary dysplasia (BPD)
