The child is an immigrant, and this is his first visit. The patient is in the 99th percentile for height and 50th percentile for weight. The child is struggling in school, and basic cognitive testing suggests he is moderately mentally disabled. His temperature is 99.5F 37.5C, blood pressure is 10768 mmHg, pulse is 90min, respirations are 17min, and oxygen saturation is 98 on room air. Laboratory values are obtained and shown below.Hemoglobin: 9 gdLHematocrit: 30MCV: 110 fLLeukocyte count: 5,500mm3 with normal differentialPlatelet count: 192,000mm3Serum:Na: 140 mEqLCl-: 101 mEqLK: 4.4 mEqLHCO3-: 24 mEqLBUN: 20 mgdLGlucose: 90 mgdLCreatinine: 1.0 mgdLCa2: 10.0 mgdLAST: 12 ULALT: 10 ULThe patient is started on vitamin B9 and B12. Which of the following interventions could decrease the risk for cardiac complications the most in this patient?? A: Iron, B: Pyridoxine, C: Fish oil, D: Vitamin D, E: No interventions needed,  <response>: Based on the information provided, this 11-year-old boy has macrocytic anemia likely due to vitamin B9 folate and B12 deficiency. He is tall for his age but has a normal weight. He also has some developmental delays. His vital signs are relatively normal. The lab results show he has anemia with high MCV, low hemoglobin and hematocrit. His electrolytes, renal function, liver enzymes, and glucose are normal. The goal would be to treat his vitamin deficiencies to improve his anemia. Since he has no evidence of iron deficiency, iron supplementation would not be helpful. Pyridoxine vitamin B6 deficiency does not cause macrocytic anemia so pyridoxine would not help. Fish oil and vitamin D may have general health benefits but would not specifically treat his anemia. No interventions are not needed since he clearly has vitamin deficiencies causing anemia that should be treated.Therefore, the intervention that would decrease his risk of cardiac complications the most would be to continue the vitamin B9 folate and B12 that was already started. B: Pyridoxine
