The nurse is caring for a newborn with suspected Patent Ductus Arteriosus (PDA). What signs and symptoms should the nurse expect to find when assessing the newborn? (Select All That Apply).

A. Clear bilateral breath sounds are not typical in PDA; instead, crackles or signs of respiratory distress may be present. B. Dyspnea (difficulty breathing) is common due to the increased pulmonary blood flow from the PDA. C. A machine-like murmur heard at the right upper sternal border is characteristic of PDA. D. Cyanosis is typically not present in isolated PDA unless the PDA is large and leads to right-to-left shunting. E. Difficulty feeding is a common symptom because the newborn may tire easily due to inefficient circulation and increased work of breathing.
