What is the appropriate action for managing a newborn with persistent hypoglycemia?

The appropriate action for managing a newborn with persistent hypoglycemia is to begin 10% IV glucose while continuing to breastfeed. This approach is optimal because it addresses the immediate need to correct the hypoglycemia through intravenous glucose administration, which provides a rapid source of glucose to raise blood sugar levels.

Moreover, continuing to breastfeed supports the infant's nutritional needs and encourages the establishment of breastfeeding, which has numerous long-term benefits for both the infant and mother. Breastfeeding can help stabilize blood sugar levels in the long run as it promotes metabolic response and provides vital nutrients.

In contrast, solely starting with immediate IV fluids, while it provides an immediate source of glucose, does not incorporate the benefits of breastfeeding and may overlook the ongoing care and support that breastfeeding offers. Consulting a pediatrician and delaying feeding would not be an ideal immediate response as timely management of hypoglycemia is crucial. Switching to formula feeding exclusively may not be necessary or beneficial if breastfeeding is already being established, especially since maintaining lactation can be important for both the mother and infant's health.
