Answer

Answer c. Most neonates lose heat in the operating room environment via radiant and convective losses, and a radiant heat lamp is very effective at maintaining adequate heat homeostasis. Increasing ambient room temperature is also an acceptable method of warming, although not as effective as radiant heating.
