Review Question - QID 214369

A 28-year-old woman, gravida 1 para 0, at 38 weeks gestation presents to the emergency department with painful contractions. She denies any vaginal bleeding or rupture of membranes and endorses normal fetal movement. Her pregnancy has been uneventful, and she is otherwise healthy. Her temperature is 99°F (37.2°C), blood pressure is 105/75 mmHg, pulse is 96/min, and respirations are 18/min. The tocometer demonstrates contractions occurring every 3 minutes, and fetal heart tracing demonstrates a pulse of 145/min and moderate variability with no decelerations. Pelvic examination is remarkable for an 8 cm cervical dilation and 100% effacement. The fetal head is at station -1. The patient is reassessed 3 hours later and her cervix has remained dilated at 8 cm. The tocometer demonstrates contractions every 5 minutes. The appropriate intravenous medication is administered via infusion pump. Which of the following abnormalities is most likely associated with the administered medication?
