Final answer:
Nonbilious projectile emesis in a two-month-old baby may be indicative of pyloric stenosis, and the appropriate step in management would be to consult a pediatric surgeon for further evaluation and potential surgical correction.
Step-by-step explanation:
Nonbilious projectile emesis in a two-month-old baby can be indicative of certain conditions that require appropriate management. The first step in management is to evaluate the baby's hydration status and stabilize it if necessary. In this case, the baby is likely experiencing pyloric stenosis, which is a narrowing of the opening from the stomach to the small intestine. The appropriate step in management would be to consult a pediatric surgeon for further evaluation and potential surgical correction.
