A child diagnosed with PDA would most likely exhibit which of the following symptoms?

A child diagnosed with patent ductus arteriosus (PDA) is most likely to exhibit increased respiratory distress due to the characteristic hemodynamic changes associated with this condition. In PDA, the ductus arteriosus remains open after birth, allowing oxygenated blood from the aorta to flow back into the pulmonary artery and increase the blood flow to the lungs. This increased pulmonary blood flow can lead to pulmonary congestion and elevated pressures in the pulmonary circulation, resulting in respiratory distress.

Increased respiratory rate and effort, as the child struggles to maintain adequate oxygenation, are commonly observed. Symptoms such as wheezing, coughing, and retractions may also be present as the lungs become overloaded with fluid. Recognizing these symptoms is important in managing and treating a child with PDA, as prompt interventions may be necessary to alleviate these respiratory complications.
