A nurse is caring for a patient who is at 22 weeks of gestation and has been unable to control her gestational diabetes mellitus with diet and exercise. Which of the following medications should the nurse anticipate the provider will prescribe for the patient?
Repaglinide
Glipizide
Insulin
Acarbose
The Correct Answer is C
Choice A rationale
Repaglinide is an oral diabetes medication that helps control blood sugar levels by causing the pancreas to produce insulin. However, it is not typically the first choice for treating gestational diabetes. It is usually used for type 2 diabetes and is not commonly recommended during pregnancy.
Choice B rationale
Glipizide is another oral diabetes medication that works by stimulating the pancreas to produce insulin. Like repaglinide, it is not typically used as a first-line treatment for gestational diabetes and is not commonly recommended during pregnancy.
Choice C rationale
Insulin is the most common treatment for gestational diabetes. It does not cross the placenta and thus does not cause hypoglycemia in the baby. It can be used safely during pregnancy and is effective in controlling blood glucose levels.
Choice D rationale
Acarbose is an alpha-glucosidase inhibitor, which works by slowing the absorption of carbohydrates from the intestine. It is not typically used in pregnancy due to lack of safety data.

Correct Answer is C
Explanation
Choice A rationale
While congenital anomalies, growth restriction, and fetal distress during labor can occur in pregnancies, they are not directly associated with polyhydramnios. Polyhydramnios is a condition characterized by an excessive accumulation of amniotic fluid in the uterus during pregnancy.
Choice B rationale
Carrying more than one fetus can lead to a condition known as twin-to-twin transfusion syndrome, which can result in polyhydramnios in one twin and oligohydramnios in the other. However, carrying more than one fetus does not directly mean the mother will experience polyhydramnios.
Choice C rationale
Polyhydramnios is indeed characterized by an excessive amount of amniotic fluid present in the uterus during pregnancy. This can be due to various reasons such as fetal abnormalities, maternal diabetes, and others.
Choice D rationale
An elevated level of alpha-fetoprotein (AFP) in the amniotic fluid can be an indication of certain fetal abnormalities, but it is not a direct indicator of polyhydramnios.
Correct Answer is A
Explanation
Choice A rationale
This is the correct answer. In infants of mothers with poorly controlled diabetes, hyperinsulinemia can lead to increased oxygen consumption and metabolic rate, which can contribute to the development of respiratory distress syndrome.
Choice B rationale
Increased blood viscosity is not the most likely cause of respiratory distress in a macrosomic newborn of a mother with poorly controlled diabetes.
Choice C rationale
A brachial plexus injury is a potential complication of delivery for macrosomic infants, but it is not a cause of respiratory distress syndrome.
Choice D rationale
Increased deposits of fat in the chest and shoulder areas can make delivery more difficult and can increase the risk of birth injuries, but they are not the most likely cause of respiratory distress syndrome in a macrosomic newborn of a mother with poorly controlled diabetes.
