The birth was unremarkable and the mother is known to be diabetic. The child is examined by the on-call physician, who detects a single loud S2. The chest X-ray shows an egg-shaped heart. Which medication below would possibly prevent further progression of the patients symptoms?? A: Indomethacin, B: Low-dose aspirin, C: Prostaglandins E2, D: Erythromycin ointment, E: Vitamin K,  <response>: This is a clinical vignette describing a newborn with symptoms of cyanosis and respiratory distress. The description of a single loud S2 heart sound and egg-shaped heart on chest X-ray indicates a diagnosis of patent ductus arteriosus PDA. A PDA is failure of closure of the ductus arteriosus after birth, which allows continued shunting of blood from the aorta to the pulmonary artery. This results in pulmonary overcirculation and the described symptoms. Of the medication choices provided, prostaglandins help maintain patency of the ductus arteriosus before birth but their discontinuation after birth promotes ductal closure. Therefore, prostaglandin inhibition with indomethacin would be the appropriate choice to promote ductal closure and prevent worsening of symptoms in this patient.C: Prostaglandins E2
