After delivering an apneic newborn displaying cyanosis, what is the first action to take?

The first action to take after delivering an apneic newborn displaying cyanosis is to stimulate the infant. This step is crucial because gentle stimulation can help initiate breathing and increase the infant's heart rate. In many cases, a newborn is born with the ability to breathe spontaneously if proper stimulation is provided. This may involve rubbing the back, flicking the soles of the feet, or increasing the environmental stimuli.

If stimulation does not lead to improvement in the infant's condition, then further interventions such as administering oxygen, suctioning, or CPR may become necessary. However, immediate physical stimulation should always be the first response to encourage the newborn to breathe on their own.
