Final answer:
After administering intravenous epinephrine to a newborn, you should pause compressions and reassess the baby's heart rate 60 seconds later.
Step-by-step explanation:
In the context of resuscitation and the administration of intravenous epinephrine in a newborn, it is recommended to pause compressions and reassess the baby's heart rate 60 seconds after administration. This interval allows enough time for the drug to circulate and exert its effects, which include increasing heart rate and improving blood flow to vital organs. In the critical setting of resuscitation, where Apgar scores are used to quickly assess a newborn's health, continuing high-quality chest compressions and timely reassessment are crucial components of neonatal resuscitation.
