What is the most likely cause of respiratory distress syndrome in a term macrosomic newborn whose mother has poorly controlled type 2 diabetes?
Increased deposits of fat in the chest and shoulder area.
Hyperinsulinemia.
Brachial plexus injury.
Increased blood viscosity.
The Correct Answer is B
Choice A rationale
Increased deposits of fat in the chest and shoulder area are not typically associated with respiratory distress syndrome in a term macrosomic newborn whose mother has poorly controlled type 2 diabetes.
Choice B rationale
Hyperinsulinemia is a condition in which there are excess levels of insulin circulating in the blood. In the case of a term macrosomic newborn whose mother has poorly controlled type 2 diabetes, the baby’s pancreas may produce extra insulin in response to the mother’s high blood glucose levels. This excess insulin can delay surfactant production, which is needed for lung maturation, leading to respiratory distress syndrome.
Choice C rationale
Brachial plexus injury is a type of birth injury that can occur due to the baby’s large size and difficulty being born. However, it is not the most likely cause of respiratory distress syndrome in a term macrosomic newborn whose mother has poorly controlled type 2 diabetes.
Choice D rationale
Increased blood viscosity can occur in newborns of mothers with poorly controlled diabetes due to polycythemia (an abnormally high number of red blood cells). However, this is not the most likely cause of respiratory distress syndrome in a term macrosomic newborn.
