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

The 17-year-old pregnant female patient presents for her first prenatal visit. The nurse plans care based on which understanding of recommended screening?

The nurse performs a 12-lead electrocardiogram on the 6-hour-old 39-week-gestation neonate admitted to the neonatal intensive care unit for respiratory distress syndrome. The baby initially required continuous positive airway pressure (CPAP) but is now comfortably tachypneic on room air, with an oxygen saturation of 98% in both the right and left hands. The chest x-ray indicates transient tachypnea of the newborn. Right axis deviation suggesting right ventricular hypertrophy is noted on the ECG. The nurse anticipates the provider to give the parents which information?
