<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:Three weeks after birth, an infant girl develops episodes of apnea. She has become increasingly lethargic over the past two days, and experienced two episodes of apnea lasting 10 seconds each within the last day. She was born at 31 weeks of gestation and weighed 1600-g 3-lb 8-oz. Apgar scores were 4 and 7 at 1 and 5 minutes, respectively. She takes no medications. Her temperature is 36.7C 98.0F, pulse is 185min, respirations are 60min and irregular, and blood pressure is 7035 mm Hg. She appears pale. Physical examination shows no abnormalities. Laboratory studies show a hemoglobin of 6.5 gdL, a reticulocyte count of 0.5, and a mean corpuscular volume of 92 μm3. Leukocyte count, platelet count, total bilirubin and indirect bilirubin are all within reference range. Which of the following is the most likely underlying mechanism of this patients anemia?? A: Defective δ-aminolevulinic acid synthase, B: Bone marrow suppression, C: Glucose-6-phosphate dehydrogenase deficiency, D: Iron deficiency, E: Impaired erythropoietin production,  <response>: This is a question about an infant girl with anemia who is experiencing apnea and lethargy. The key details in the question stem are: - 3 weeks old - Episodes of apnea - Increasingly lethargic - Born premature at 31 weeks gestation- Low birth weight of 1600g- Low Apgar scores - Vital signs indicate respiratory distress and hypotension- Physical exam normal- Labs show hemoglobin of 6.5 gdL, low reticulocyte count, normal MCV- Other counts within normal rangeBased on the premature birth, low birth weight, respiratory issues, and low hemoglobin, this infant likely has anemia of prematurity. The normal MCV rules out microcytic or macrocytic anemias. The normal reticulocyte count indicates this is not due to increased destruction of RBCs. The normal bilirubin argues against hemolysis. The most likely cause is impaired erythropoietin production secondary to prematurity. Erythropoietin is the hormone that stimulates RBC production and is often low in premature infants.E: Impaired erythropoietin production
