The antibiotics are continued after the cesarean delivery. On postoperative day 3, the patient remains febrile and symptomatic with uterine fundal tenderness. No masses are appreciated by pelvic examination. She is successfully breast-feeding and her breast examination is normal. Which antibiotic should be initiated to provide better coverage?

A 32-year-old G2P0101 presents to labor and delivery at 34 weeks of gestation, complaining of regular uterine contractions about every 5 minutes for the past several hours. She has also noticed the passage of a clear fluid per vagina. A nurse places the patient on an external fetal monitor and calls you to evaluate her status. The external fetal monitor demonstrates a reactive fetal heart rate tracing, with regular uterine contractions occurring about every 3 to 4 minutes. On sterile speculum examination, the cervix is visually closed. A sample of pooled amniotic fluid seen in the vaginal vault is fern and nitrazine-positive. The patient has a temperature of 38.8°C, pulse 102 beats per minute, blood pressure 100/60 mm Hg, and her fundus is tender to deep palpation. Her admission blood work comes back indicating a WBC of 19,000. The patient is very concerned because she had previously delivered a baby at 35 weeks who suffered from respiratory distress syndrome (RDS). You perform a bedside sonogram, which indicates oligohydramnios and a fetus whose size is appropriate for gestational age and with a cephalic presentation. Which of the following is the most appropriate next step in the management of this patient?
A. Administer betamethasone
B. Administer tocolytics
C. Place a cervical cerclage
D. Administer antibiotics
E. Perform emergent cesarean section
D. Administer antibiotics

A 30-year-old G2P1001 patient comes to see you in the office at 37 weeks gestational age for her routine OB visit. Her first pregnancy resulted in a vaginal delivery of a 9-Ib 8-oz baby boy after 30 minutes of pushing. On doing Leopold maneuvers during this office visit, you determine that the fetus is breech. Vaginal examination demonstrates that the cervix is 50% effaced and 1 to 2 cm dilated. The presenting breech is high out of the pelvis. The estimated fetal weight is about 7 lb.
