Which conditions belong on the initial differential diagnosis for Adam?

The initial differential diagnosis for Adam includes transient tachypnea of the newborn (TTN) because TTN is a common respiratory condition seen in newborns, particularly in those born via cesarean section or after a rapid delivery. It typically presents within the first few hours after birth with signs of respiratory distress such as tachypnea (increased respiratory rate), retractions, and grunting. This condition arises from delayed clearance of fluid in the lungs, and while it often resolves with supportive care, it is essential to recognize it early in an infant presenting with respiratory symptoms.

In contrast, the other conditions listed do not align with the typical clinical presentation for a newborn. Acute appendicitis generally occurs in older children and adolescents, Type I Diabetes manifests with polyuria, polydipsia, and weight loss typically in older children or adolescents, and asthma is a chronic respiratory condition that primarily affects older children and adults, often triggered by allergens or infections. Therefore, these conditions are less likely to be on the initial differential diagnosis for a newborn like Adam.
