What Should the Nurse Be Aware of with Regard to the Gastrointestinal

What should the nurse be aware of with regard to the gastrointestinal (GI) system of the newborn?

A) The newborn's cheeks are full because of normal fluid retention.
B) The nipple of the bottle or breast must be placed well inside the baby's mouth because teeth have been developing in utero, and one or more may even be through.
C) Regurgitation during the first day or two can be reduced by burping the infant and slightly elevating the baby's head.
D) Bacteria are already present in the infant's GI tract at birth, because they traveled through the placenta.
