Write answer in between .Q:One day after a 4700-g 10-lb 6-oz male newborn is delivered to a 28-year-old primigravid woman, he has bluish discoloration of his lips and fingernails. Oxygen saturation on room air is 81. Examination shows central cyanosis. A continuous machine-like murmur is heard over the left upper sternal border. A single S2 heart sound is present. Supplemental oxygen does not improve cyanosis. Echocardiography shows the pulmonary artery arising from the posterior left ventricle and aorta arising from the right ventricle with active blood flow between the right and left ventricles. Further evaluation of the mother is most likely to show which of the following?? A: Prenatal lithium intake, B: Elevated serum TSH, C: Prenatal phenytoin intake, D: Positive rapid plasma reagin test, E: Elevated fasting blood glucose,  <response>: This is a question about transposition of the great arteries TGA in a newborn, which is a congenital heart defect where the pulmonary artery arises from the left ventricle and the aorta arises from the right ventricle. The key finding in the stem is the echocardiogram showing switched origins of the great arteries. TGA is not associated with any maternal risk factors or exposures during pregnancy. The choices list various maternal conditions and exposures, but none of these are associated with increased risk of TGA in the infant.E: Elevated fasting blood glucose
