The nurse would include which of the following statements when describing the pathophysiology of gestational diabetes?

There is progressive resistance to the effects of insulin

Pregnancy fosters the development of carbohydrate cravings.

Hypoinsulinemia develops early in the first trimester

Glucose levels decrease to accommodate fetal growth.

Answer and Explanation

The Correct Answer is A

A. There is progressive resistance to the effects of insulin. During pregnancy, placental hormones (such as human placental lactogen, estrogen, and progesterone) cause increasing insulin resistance. This ensures that glucose remains available for fetal growth. However, in gestational diabetes, the pancreas cannot compensate with increased insulin production, leading to hyperglycemia.

B. Pregnancy fosters the development of carbohydrate cravings. While some pregnant individuals experience cravings, this is not a defining cause of gestational diabetes. The condition results from hormonal changes leading to insulin resistance, not dietary habits alone.

C. Hypoinsulinemia develops early in the first trimester. Gestational diabetes is not caused by a deficiency of insulin (hypoinsulinemia) but by insulin resistance. In fact, insulin production often increases, but it is insufficient to overcome the resistance caused by placental hormones.

D. Glucose levels decrease to accommodate fetal growth. In a normal pregnancy, glucose levels remain stable, and the fetus actively takes glucose from maternal circulation. However, in gestational diabetes, maternal glucose levels rise due to insulin resistance, increasing the risk of fetal overgrowth (macrosomia).

Correct Answer is B

Explanation

A. Induction of labor with intravenous oxytocin. Induction is contraindicated in cases of abruptio placentae with a Category III fetal heart rate tracing, as labor induction can worsen fetal distress and maternal bleeding. An immediate cesarean section is the safest intervention to prevent fetal and maternal complications.

B. An emergency cesarean section. A Category III fetal heart rate tracing with minimal variability and a prolonged deceleration indicates severe fetal distress, requiring immediate delivery. Partial abruptio placentae can cause fetal hypoxia, maternal hemorrhage, and potential fetal demise. The priority is an emergency cesarean section to ensure the best outcome for both mother and baby.

C. In-hospital fetal monitoring for 48 hours. Continuous monitoring is essential in cases of mild abruptio placentae without fetal distress, but in this case, a Category III tracing indicates an immediate threat to the fetus, making waiting inappropriate.

D. Discharge home on strict bed rest. Abruptio placentae is a serious obstetric emergency, and home management is never appropriate when fetal distress is present. Immediate intervention is necessary to prevent fetal and maternal complications.

A. Midplane contracture of the pelvis B. Disproportion of the pelvis. C. Low-lying placenta D. Compromised bearing-down efforts as a result of pain medication

Correct Answer is C

Explanation

A. Midplane contracture of the pelvis. Pelvic contractures can lead to dystocia by restricting the fetal head's descent. A midplane contracture narrows the pelvic midsection, making labor prolonged and difficult. This is a common cause of dystocia.

B. Disproportion of the pelvis. Cephalopelvic disproportion (CPD), where the fetal head is too large for the maternal pelvis, is a well-known cause of dystocia. It often results in prolonged labor, failure to progress, and the need for cesarean delivery.

C. Low-lying placenta. A low-lying placenta does not directly cause dystocia. Instead, it may lead to placenta previa, which often requires cesarean delivery before labor even begins. Since it does not typically cause prolonged or difficult labor, it is the least common cause of dystocia.

D. Compromised bearing-down efforts as a result of pain medication. Excessive pain medication, especially epidurals or narcotics, can weaken maternal pushing efforts, leading to prolonged second-stage labor. This is a recognized cause of dystocia, particularly in multiparous women.
