What nursing strategy is essential to minimize hypothermia risk for a preterm neonate?

• A. Establish and maintain a neutral thermal environment using radiant warmer or incubator; pre-warm surfaces; minimize exposure.
• B. Keep the infant at room temperature and minimize warming to prevent overheating.
• C. Use cold surfaces to stimulate metabolic activity.
• D. Rely on ambient room temperature without radiant warming.

Answer: (A)

Premature infants have an underdeveloped ability to regulate body temperature and lose heat rapidly due to a large surface area relative to their weight, thin skin, and limited brown fat. The main idea is to create a neutral thermal environment, where the infant’s metabolic rate stays low and heat loss is minimized. Using a radiant warmer or incubator provides a controllable heat source to keep the infant’s skin and core temperature within a safe range. Pre-warming surfaces reduces the chill that happens when the baby is laid down, and minimizing exposure helps prevent heat loss from air currents, evaporation, and radiant cooling. Keeping the infant swaddled or covered with warm blankets and a hat, along with ongoing temperature monitoring, ensures stability and reduces the energy the baby would otherwise spend on thermogenesis. Leaving the infant at room temperature or on cold surfaces would increase heat loss and metabolic demand, risking hypothermia and related complications.
