Which physical signs could indicate a risk for hyperbilirubinemia?

Choice A reason:

All milk- and lactose-containing formulas, including breast milk, must be stopped during infancy. Soy protein is the formula of choice for newborns and infants with galactosemia. Breast milk should not be used in newborns and infants with galactosemia because it contains galactose, which they cannot metabolize properly.

Choice B reason:

Adding amino acids to the breast milk will not help the newborn with galactosemia, because the problem is not a lack of amino acids, but a deficiency of the enzyme that breaks down galactose. Amino acids are the building blocks of proteins, not sugars.

Choice C reason:

Substituting a lactose-containing formula for breast milk will worsen the condition of the newborn with galactosemia because lactose is composed of glucose and galactose. The newborns will still be exposed to galactose, which will accumulate in the blood and tissues and cause damage.

Choice D reason:

Giving the appropriate enzyme along with breast milk is not a feasible option for the newborn with galactosemia, because there is no oral enzyme replacement therapy available for this condition. The only treatment is dietary restriction of galactose.

Choice A reason:

Scant scalp hair is not an expected finding for a newborn who is post-term. Scant scalp hair is more common in preterm infants who have not developed fully.

Choice B reason:

Copious vernix is not an expected finding for a newborn who is post-term. Vernix is a white, cheesy substance that covers the skin of the fetus and protects it from the amniotic fluid. Vernix is usually abundant in preterm infants and decreases as gestation progresses.

Choice C reason:

Increased subcutaneous fat is not an expected finding for a newborn who is post-term. Increased subcutaneous fat is a sign of adequate nutrition and growth, which is more likely in term infants. Post-term infants may have reduced subcutaneous fat due to placental insufficiency and decreased nutrient supply.

Choice D reason:

Dry, cracked skin is an expected finding for a newborn who is post-term. Dry, cracked skin is a result of prolonged exposure to the amniotic fluid, which causes dehydration and desquamation of the skin. Post-term infants may also have meconium staining on their skin due to fetal distress.
