Final answer:
c) Crackles
In neonates with Respiratory Distress Syndrome, you would expect to hear crackles when auscultating their lungs due to insufficient pulmonary surfactant and subsequent difficulty inflating the lungs.
Step-by-step explanation:
When auscultating over the lungs of a neonate with Respiratory Distress Syndrome (RDS), you would expect to hear crackles. RDS is primarily seen in infants born prematurely and results from insufficient production of pulmonary surfactant, which is crucial for keeping the airways open. The lack of surfactant leads to difficulty inflating the lungs and poor gas exchange, resulting in crackles that can be heard during auscultation due to the collapsing of small airways and alveoli.
