A pregnant woman is just admitted to the emergency room after a head on auto accident. Her body appears to be uninjured. The nurse carefully monitors the woman for which complication(s) of pregnancy? (Select all that apply)

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.

A. Oral hypoglycemic medications. While some oral hypoglycemic agents, such as metformin or glyburide, are used in gestational diabetes, the first-line treatment is always dietary modification and exercise. Medications are only introduced if blood glucose levels remain uncontrolled with lifestyle changes.

B. Diet control and exercise. The initial treatment for gestational diabetes focuses on controlling blood glucose through dietary adjustments, portion control, and regular physical activity. If lifestyle modifications fail to maintain glucose levels within the target range, insulin or oral medications may be introduced.

C. Inhaled insulin. Inhaled insulin is not commonly used in pregnancy because its safety and efficacy for gestational diabetes have not been well established. Insulin therapy, if needed, is typically administered via subcutaneous injection rather than inhalation.

D. Regular insulin injections. Insulin therapy is considered if diet and exercise alone fail to control blood glucose levels. However, it is not the first-line treatment, as many women can successfully manage gestational diabetes without requiring insulin therapy.
