What risks are present in infants born to mothers who receive no or little prenatal care?

Correct Answer-LBW


premature birth


Maternal iron-deficiency anemia


Increased neonatal mortality




Describe the fetal response to mothers with diabetes Correct Answer-Because glucose

crosses the placenta, the baby's BG increases as the mom's does. Insulin does not cross the

placenta and the fetal pancreas does not produce it until 20 weeks. So, before insulin

production, the increased BG leads to restricted growth. Once the insulin is produced, it

produces rapidly to respond to the high BG, and these high levels trigger rapid fetal growth—

> hepatosplenomegaly, cardiomegaly, increased head size




What is commonly seen in IDM immediately after birth? Why? Correct Answer-

Hypoglycemia


The sudden withdrawal from maternal glucose + continued production of insulin




What conditions does an IDM present with? Correct Answer-Birth trauma r/t

cephalopelvic disproportion

Hypoglycemia


RDS because inc insulin inhibits surfactant production


Polycythemia & hyperviscosity bc inc insulin & BG inc metabolic rate and oxygen consumption


Iron deficiency bc polycythemia leaches iron


Hyperbilirubinemia from inc rbc destruction


CV & congenital malformations


Electrolyte disturbances (low Ca and Mg)




What is pre-eclampsia? Correct Answer-Inc BP, proteinuria, edema that occurs around 20
