The patient was born at 35 weeks gestation to a 30-year-old gravida 2 via vaginal delivery. The pregnancy and labor were uncomplicated. The patient required no resuscitation after delivery and was discharged from the hospital on day two of life. His mother now reports that the patient has been exclusively breastfed since birth, and she says that feedings have been going well, and that the patient appears satisfied afterwards. The patient feeds for 30 minutes every two hours and urinates 8-10 times per day. The patients mother reports that she eats a varied diet that includes animal products, but she worries that the patient is not meeting his nutritional needs with breastmilk alone. The patients height and weight at birth were in the 15th and 20th percentile, respectively. His height and weight are now in the 20th and 25th percentile, respectively. His temperature is 98.1F 36.7C, blood pressure is 5846 mmHg, pulse is 128min, and respirations are 34min. On physical exam, the patient appears well-developed and well-nourished. He has mild conjunctival pallor.Which of the following is the most appropriate guidance regarding this patients nutritional needs?? A: No changes are necessary to his diet, B: Add cows milk to his diet, C: Add pureed foods to his diet, D: Supplement his diet with formula, E: Supplement his diet with iron and vitamin D,  <response>: This is a question about nutritional guidance for a 5-month-old breastfed infant. The key points from the stem are:- 5-month-old male infant - Born at 35 weeks gestation - Exclusively breastfed since birth- Mother reports feedings are going well and infant appears satisfied- Mother eats varied diet with animal products- Infants growth percentiles are appropriate 20-25th percentile- Physical exam is normal except for mild conjunctival pallorThe choices focus on whether any changes are needed to the infants current exclusively breastfed diet. Conjunctival pallor suggests the infant may be mildly anemic, likely iron deficiency anemia which is common in exclusively breastfed infants around 6 months of age as iron stores from pregnancy become depleted. Anemia can be confirmed with a CBC and iron studies. Therefore, supplementing with iron choice E would be appropriate. No changes A, adding cows milk B or pureed foods C would not address the likely iron deficiency. Formula D would provide iron but is not necessary since the infant is breastfeeding well.E: Supplement his diet with iron and vitamin D
