Default congenital heart disease

A previously normal newborn infant in a community hospital nursery is noted to be cyanotic at 14 h of life. She is placed on a face mask with oxygen flowing at 10 LPM. She remains cyanotic, and her pulse oximetry reading does not change. An arterial blood gas shows her PaO2 to be 23 mmHg. Bilateral breath sounds are present, and she has no murmur. She is breathing deeply and quickly, but she is not retracting. You are concerned about congenital heart disease. While you are waiting for the transport team from the nearby children's hospital, you should initiate which of the following?
a. Indomethacin infusion
b. Saline infusion
c. Adenosine infusion
d. Prostaglandin E1 infusion
e. Digoxin infusion

the newborn has caynosis indicating right to left shunt n in all such situation the survival is possible with patent ductus arteriosus which conducts oxygenated blood from aorta to pulmonary artery n steping up po2 in left side of heart so the ans is PGE 1 infusion
