Final answer:
The nurse should monitor the infant's respirations closely and prepare to administer oxygen.
Step-by-step explanation:
The nurse should prepare to monitor the infant's respirations closely and prepare to administer oxygen.
The mother's use of IV morphine during labor and delivery can result in the newborn experiencing respiratory depression. Monitoring the infant's respirations is essential to ensure their well-being and catch any signs of respiratory distress. If the infant's respirations are inadequate, oxygen may be administered to support their breathing.
