A nurse is assisting with the care of a newborn following a vaginal delivery. Which of the following actions should the nurse perform first?

Choice A rationale Clamping the umbilical cord is a necessary step in the transition to extrauterine life but is not the immediate priority. Delayed cord clamping is often practiced to allow for increased blood volume and iron stores in the newborn. While important for long-term health, it does not address the immediate physiological need for gas exchange. Clearing the airway must occur first to ensure the infant can begin breathing independently once the placental circulation is eventually cut off. Choice B rationale Clearing the respiratory tract is the highest priority following delivery to ensure a patent airway. A newborn's mouth and nose may be filled with amniotic fluid, mucus, or meconium, which can be aspirated into the lungs or obstruct breathing. By suctioning the mouth and then the nose, the nurse facilitates the infant's first breath and prevents respiratory distress. This action follows the primary ABC (Airway, Breathing, Circulation) protocol for neonatal resuscitation and stabilization. Choice C rationale Drying the infant and covering the head is vital for thermoregulation to prevent cold stress and evaporation heat loss. Newborns have a high surface-area-to-mass ratio and cannot shiver to generate heat. A normal newborn temperature is 97.7 to 99.5 degrees Fahrenheit. While maintaining warmth is crucial for metabolic stability, it cannot be addressed effectively if the infant's airway is blocked. Airway clearance must be the very first action performed to initiate life-sustaining ventilation. Choice D rationale Stimulating the infant to cry helps expand the lungs and clear fluid from the alveoli. This is often done by rubbing the back or flicking the soles of the feet. However, stimulation should only occur after the airway is cleared of obstructive fluids. If an infant is stimulated while the airway is full of secretions, they may aspirate those fluids deep into the lungs. Therefore, clearing the respiratory tract is the prerequisite action before active stimulation.
