At a routine check-up, the nurse expects the healthy 4-month-old to have met which milestone?

The baby born at 32 weeks’ gestation to a mother who is hepatitis B surface antigen negative (HBsAg-negative) is taken to the Neonatal Intensive Care Unit (NICU) for care. The neonate, who weighs 1.8 kg, requires continuous positive airway pressure of 7 cm H20, intravenous fluids containing dextrose, and intravenous caffeine. After getting consent from the mother, when is the most appropriate time to administer the hepatitis B vaccine to the baby?

The very low birth weight infant was born at 0.9 kg and now weighs 1.3 kg. The neonate is on full feeds receiving 24 kcal/oz formula with a daily kcal goal of 120 kcal/kg/day. The patient eats every 3 hours around the clock. How many milliliters does the nurse administer with each feeding? Enter your answer using a whole number.
