Final answer:
If a newborn is not breathing after the 5 initial steps, it may indicate a problem with the respiratory system and require medical intervention.
Step-by-step explanation:
If a newborn is 36 weeks gestation with no muscle tone or breathing present and after the 5 initial steps the newborn is still not breathing, this indicates a potential problem with the respiratory system. In this case, the newborn may require immediate medical attention and intervention to establish breathing. Possible interventions could include positive pressure ventilation, intubation, or administration of oxygen.
