A nurse is caring for a newborn immediately following delivery. After assuring a patent airway, which of the following actions should be the nurse's priority?

Choice B rationale The priority for a newborn immediately after delivery is to prevent cold stress through thermoregulation. Newborns lose heat rapidly via evaporation, conduction, convection, and radiation. Drying the infant removes amniotic fluid, which prevents evaporative heat loss. Cold stress can lead to increased oxygen consumption, metabolic acidosis, and hypoglycemia. Therefore, maintaining a neutral thermal environment by drying the skin and placing the infant on the mother's chest or under a warmer is the most critical intervention. Choice A rationale Phytonadione or Vitamin K is administered to prevent vitamin K deficiency bleeding, as newborns are born with sterile guts and low clotting factor levels. While this is a standard and necessary intervention, it is not the immediate priority within the first few seconds or minutes of life. Ensuring the infant is warm and stable takes precedence over intramuscular injections. Vitamin K is typically given within the first hour of birth after the initial bonding and stabilization. Choice C rationale The Apgar score is a quick assessment of the newborn's transition to extrauterine life, performed at one and five minutes. While it is an essential tool for documenting the infant's heart rate, respiratory effort, muscle tone, reflex irritability, and color, it is an observational task. The physical action of drying the infant to prevent heat loss is a direct intervention that takes priority over the documentation of the score, as it addresses an immediate physiological threat. Choice D rationale Applying identification bands is a crucial safety measure to prevent infant abduction or misidentification. It is a standard part of the admission process to the nursery or postpartum unit. However, in the hierarchy of needs, physiological stability and thermoregulation are much more urgent than administrative safety tasks. Identification should be completed as soon as possible, but only after the infant's temperature and respiratory status have been stabilized through drying and immediate care.
