The nurse is assisting with the delivery of a term newborn. Which nursing action is most effective in promoting temperature stability through conduction?

A. Closing the doors to the room is incorrect because this primarily reduces heat loss through convection and drafts, not conduction. While it helps maintain ambient temperature, it does not directly transfer heat to the newborn through physical contact. B. Turning on the overhead radiant warmer is incorrect because radiant warmers primarily prevent heat loss through radiation, not conduction. They provide a warm environment, but the newborn does not need to be in direct contact with a warmer for conduction. C. Drying the newborn with a warm blanket is partially correct because it can prevent evaporative heat loss, but the primary heat transfer mechanism here is insulation and evaporation prevention, not conduction. D. Placing the newborn on the mother's chest is correct because conduction occurs when heat is transferred directly from one surface to another. Skin-to-skin contact allows the mother’s body heat to directly warm the newborn, helping maintain temperature stability. This method is evidence-based and also promotes bonding and breastfeeding initiation.
