Following a vaginal delivery, the nurse places the neonate under the radiant warmer, provides naso-oropharyngeal suction, and dries the neonate's skin to elicit spontaneous respirations. The newborn heart rate is 100 beats/minute and remains apneic when the nurse flicks the soles of the feet. Which action should the nurse implement next?

A. Assist neonatologist with intubation: Intubation may be required if positive pressure ventilation (PPV) is ineffective, but immediate resuscitation begins with PPV in a newborn who is apneic with a heart rate of 100 bpm. B. Provide positive pressure ventilation: The newborn is apneic despite stimulation, and the heart rate is at the lower threshold of normal. Initiating PPV is the next step in the neonatal resuscitation algorithm to establish effective ventilation and support oxygenation. C. Give blow-by oxygen via cannula: Blow-by oxygen provides minimal support and is insufficient for an apneic newborn. Effective ventilation requires PPV to ensure oxygen reaches the lungs. D. Start IV infusion in a scalp vein: IV access may be necessary later for medications or fluids, but immediate intervention focuses on airway and breathing support rather than vascular access.
