Final answer:
The next step in the Mr. SOPA ventilation correction steps, when there is no chest movement, is to increase pressure in increments up to 40cm H2O.
Step-by-step explanation:
When performing the Mr. SOPA ventilation correction steps on a term baby, if there is no chest movement after adjusting the mask, repositioning the head, suctioning the mouth and nose, and opening the mouth, the next step would be to increase pressure in 5 to 10 increments up to a maximum of 40cm H2O. The goal is to establish adequate ventilation and ensure that the lungs are being properly inflated. It is critical to perform these adjustments cautiously and to monitor the baby's response to the increased pressure.
