Final answer:
The next nursing action would be to begin positive-pressure ventilation.
Step-by-step explanation:
The next nursing action in this situation would be to begin positive-pressure ventilation.
In cases where a newborn does not respond to initial stimulation and drying, and their heart rate remains low, positive-pressure ventilation is necessary to provide the baby with oxygen and assist with the breathing process.
This intervention can help improve the baby's condition and ensure adequate oxygenation until further medical evaluation and treatment can be provided.
