Question: A parent of a preterm infant in the neonatal intensive care unit asks the nurse why the baby is in a bed with a radiant warmer. The nurse explains that preterm infants are at increased risk for hypothermia for which reason? They perspire excessively, causing a constant loss of body heat. They have a smaller body surface area than full-term newborns. They lack the subcutaneous fat that usually provides insulation. They have a limited ability to produce antibodies against infections.
