Which symptom is least likely associated with pneumonia in neonates?

In the context of pneumonia in neonates, improved feeding is least likely associated with the condition because pneumonia typically results in respiratory distress and can cause feeding intolerance. When a neonate has pneumonia, they may experience difficulty breathing, which can lead to decreased appetite or refusal to feed. Symptoms such as tachypnea, grunting, and increased work of breathing can significantly affect a baby's ability to feed properly.

Other symptoms commonly associated with pneumonia in neonates include apnea, which is an interruption in breathing that can occur due to the stress of infection or decreased oxygenation. Abdominal distention can also occur, as it may be related to feeding difficulties or gas buildup due to gastrointestinal disturbances secondary to respiratory illness. Pathologic jaundice, while not as specific to pneumonia, can occur in neonates due to various underlying issues, including infections that can affect liver function or cause hemolysis.

Recognizing these symptoms is crucial for early diagnosis and intervention in neonates with pneumonia, but improved feeding stands out as the symptom least likely to present in cases of this respiratory condition.
