Her temperature is 98.6°F (37°C), blood pressure is 135/75 mmHg, pulse is 109/min, and respirations are 22/min. A non-stress test is non-responsive, and a biophysical profile demonstrates abnormal fetal breathing, fetal activity, and fetal muscle tone. An amniotic fluid sample is taken which demonstrates a lecithin/sphingomyelin ratio of 1.9. Which of the following is the next best step in the management of this patient?
