A nurse is evaluating a care plan for a formula-fed newborn diagnosed with colic whose parents report increased crying and feeding difficulties. Which of the following nursing actions should the nurse implement first to address the newborn's symptoms and support the family?

A. Instruct the parents to provide frequent burping with every ounce of formula and to hold the infant upright for 30 minutes after feeding: Colic in formula-fed infants is often associated with swallowed air and gastrointestinal discomfort. Encouraging frequent burping and upright positioning after feeding helps reduce gas buildup, reflux, and discomfort, directly addressing the newborn’s symptoms. B. Encourage the parents to use rocking and swaddling to manage colic symptoms without the need to modify feeding techniques: Soothing techniques can help comfort the infant but do not address the underlying feeding-related factors contributing to colic. They are supportive but not the first-line intervention. C. Recommend switching the infant to a soy-based formula: Formula changes may be considered if burping and positioning are ineffective, but they should not be the first intervention without evaluating feeding practices and tolerance first. D. Advise the parents to increase the interval between feedings to reduce digestive workload on the infant: Increasing intervals may lead to longer periods of hunger and potential feeding difficulties. Proper feeding techniques and managing gas are safer first interventions for colic symptoms.
