Review Question - QID 108752

A 31-year-old G1P0000 woman presents to the obstetric service for a scheduled induction of labor at 39 weeks of gestation due to poorly controlled gestational diabetes. Her pregnancy was largely uncomplicated aside from abnormal 1-hour and 3-hour glucose tolerance tests, for which diet and lifestyle management were initially recommended. Due to poor glycemic control despite these interventions, the patient was started on insulin. Postprandial glucose levels were in the 170-180 mg/dL range throughout the remainder of her pregnancy. She has a family history of diabetes in her mother and grandmother as well as hypertension in her father and preeclampsia in her sister. The patient had an appropriate weight gain of 26 pounds during this pregnancy with a pre-pregnancy BMI of 22.4 kg/m^2. At her last ultrasound 1 month ago, the estimated fetal weight was 4100 g and upon arrival on the labor floor, the updated measurement is 4560 g. Her temperature is 98.6°F (37°C), blood pressure is 118/72 mmHg, pulse is 81/min, and respirations are 12/min. The patient continues to desire a vaginal delivery and is subsequently induced. After 24 hours, the patient experiences shoulder dystocia. The mother’s hips are flexed and pressure is applied to the suprapubic region without improvement and internal rotation is ultimately required to deliver a male infant after 3 minutes. 1 hour after delivery, the infant is found to have an absent Moro reflex on the left side. He is also found to have the posture shown in Figure A. Which of the following would most likely have prevented this infant’s complication?
