Q38. A 3-dаy-оld infаnt is аdmitted tо the neоnatal unit after being born at 32 weeks gestation. The baby is being monitored for prematurity-related complications and has been stable, but the nursing staff has noticed some subtle signs of distress over the last 12 hours. The infant's vital signs are as follows: heart rate 170 bpm, respiratory rate 56 breaths per minute, and oxygen saturation is 92% on room air. The infant is on minimal respiratory support and is not requiring significant intervention for respiratory distress. Physical Examination: On examination, the infant appears mildly tachypneic and has a slightly increased work of breathing. A continuous "machinery-like" murmur is heard best at the left upper sternal border. The heart sounds are normal with no additional murmurs heard. The infant’s color is slightly dusky around the lips, and a slight bounding pulse is noted in the upper extremities compared to the lower extremities. The abdomen is soft, and no hepatomegaly is present. Based on the clinical presentation, which of the following findings is most characteristic of a Patent Ductus Arteriosus (PDA) in a premature infant?
