Write answer in between .Q:A 4-day-old male newborn is brought to the physician because of increasing yellowish discoloration of his skin for 2 days. He was born at 38 weeks gestation and weighed 2466 g 5 lb 7 oz; he currently weighs 2198 g 4 lb 14 oz. Pregnancy was complicated by pregnancy-induced hypertension. The mother says he breastfeeds every 3 hours and has 3 wet diapers per day. His temperature is 37C 98.6F, pulse is 165min, and respirations are 53min. Examination shows jaundice and scleral icterus. The anterior fontanelle is mildly sunken. The abdomen is soft and nontender; there is no organomegaly. The remainder of the examination shows no abnormalities. Laboratory studies show:Hematocrit 58SerumBilirubin_ Total 20 mgdL_ Conjugated 0.8 mgdLWhich of the following is the most likely cause of these findings?? A: Increased breakdown of fetal RBCs, B: Elevated β-glucuronidase in breast milk, C: Inadequate breastfeeding, D: Gram-negative infection, E: Defective alpha-globin chains of hemoglobin,  <response>: This is a question about neonatal jaundice in a 4-day-old male newborn. The key findings are increasing jaundice over 2 days, birth at 38 weeks gestation, birth weight 2466 g, current weight 2198 g, pregnancy-induced hypertension in the mother, breastfeeding every 3 hours with 3 wet diapers per day, physical exam showing jaundice and scleral icterus, mildly sunken anterior fontanelle, normal abdomen, and lab results showing hemocrit 58, total bilirubin 20 mgdL, and conjugated bilirubin 0.8 mgdL. The mildly sunken fontanelle and weight loss since birth indicate some degree of dehydration, which can contribute to jaundice. The elevated total bilirubin, especially the unconjugated portion, along with no evidence of infection or hemoglobinopathy point towards physiologic jaundice. The options describing increased breakdown of fetal RBCs and breastfeeding issues are consistent with this, while the other options do not fit. Of those two, inadequate breastfeeding seems most likely given the mildly sunken fontanelle and weight loss.C: Inadequate breastfeeding
