What is the most effective measure to promote thermoregulation in a preterm infant?

1. Using a warm room

2. Skin-to-skin contact with the mother

3. Providing frequent feedings

4. Utilizing a radiant warmer

The correct answer is: Utilizing a radiant warmer

Utilizing a radiant warmer is the most effective measure to promote thermoregulation in a preterm infant. Preterm infants are particularly vulnerable to hypothermia due to their underdeveloped skin and limited subcutaneous fat, which compromises their ability to maintain body temperature. A radiant warmer provides controlled heating and allows for monitoring of the infant's temperature in a safe environment. By directly warming the air around the infant, a radiant warmer helps prevent temperature drops that can occur immediately after birth or during early life when the infant is unable to generate sufficient heat. This method not only stabilizes the infant’s temperature but also allows for easy access for healthcare providers to perform necessary assessments and interventions. While using a warm room can help, it is less effective than a radiant warmer, as the ambient air temperature may not provide the level of warmth needed for the infant's delicate temperature regulation. Skin-to-skin contact, also known as kangaroo care, is beneficial for promoting bonding and can assist with thermoregulation, but it may not provide the consistent, controlled warmth that a radiant warmer offers, especially for preterm infants who are more susceptible to temperature fluctuations. Providing frequent feedings can support metabolic processes and overall health, but it does not directly influence the infant's
