In observing a term infant, the nurse finds signs indicative of respiratory distress. What should be the nurse's priority action?

The priority action when observing signs of respiratory distress in a term infant is to administer supplemental oxygen. This approach is essential because respiratory distress can lead to hypoxia, and providing oxygen helps to ensure that the infant receives adequate oxygenation. Timely intervention can prevent deterioration in the infant's condition and support the respiratory system.

While notifying the physician, performing a full respiratory assessment, and documenting observations are all important steps in the overall management of a neonate experiencing respiratory distress, these actions may not directly address the immediate need for oxygen. If an infant is showing signs of respiratory distress, addressing their oxygen needs takes precedence, as it can stabilize the infant quickly and effectively support their respiratory function until further evaluation and management can be performed.
