In addition, he was found to be very irritable with pale skin and profuse sweating. Finally, he was found to have cold feet with diminished lower extremity pulses. Cardiac auscultation reveals a harsh systolic murmur along the left sternal border. Notably, the patient is not observed to have cyanosis. Which of the following treatments would most likely be effective for this patients condition?? A: Leukotriene E4, B: Prostaglandin E1, C: Prostaglandin E2, D: Prostaglandin I2, E: Thromboxane A2,  <response>: This is a clinical vignette describing a newborn with symptoms of heart failure, including rapid breathing, irritability, sweating, cold extremities, and a systolic heart murmur. The lack of cyanosis indicates this is not a cyanotic heart defect. The symptoms are consistent with a diagnosis of patent ductus arteriosus PDA, which is a condition where the ductus arteriosus fails to close after birth, resulting in left to right shunting of blood. Prostaglandin E2 helps keep the ductus arteriosus open in utero, so after birth, discontinuing prostaglandin will allow the PDA to close. Therefore, the best answer is prostaglandin E2 inhibition.B: Prostaglandin E1
