Review Question - QID 109920

A 19-year-old G1P0 presents to the emergency department with abdominal pain. The pain has been recurring every 3 to 5 minutes for the past 5 hours. She denies having regular prenatal care but recalls that her last menstrual period was about 9 months ago. She denies using any substances or drugs. Her temperature is 98°F (37°C), blood pressure is 120/60 mmHg, pulse is 120/min, and respirations are 8/min. Tenderness is elicited in the lower abdominal quadrants. Clear fluid is seen in her vaginal vault with a fetal crown seen at 10 cm cervical dilation and +1 station. The patient is emergently taken into the labor and delivery suite, where she delivers a male infant with APGAR scores of 9 and 9 at 5 and 10 minutes, respectively. Several hours after delivery, the nurse notes that the infant is very irritable and crying in high pitches. The infant appears very diaphoretic with a runny nose and flailing limbs. What is the most appropriate pharmacological treatment for this patient?
