A 5-day-old infant who was delivered at home has abdominal distension and poor feeding. The mother is worried that the infant is constipated because he didn’t have a first stool until yesterday and has only passed a small amount of meconium. What will the primary care pediatric nurse practitioner do?

Obtain a sweat chloride skin test to evaluate for possible cystic fibrosis. Order an abdominal radiograph and refer the infant to a pediatric surgeon. Prescribe glycerin suppositories to use as needed until bowel function is normal. Suggest that the mother increase her fluid intake to help with constipation.
