A nurse is admitting a client who is at 39 weeks of gestation and in active labor.The client reports being positive for group B streptococcus (GBS) when screened at 36 weeks of gestation.Which of the following actions should the nurse expect to take?

Choice A rationaleCesarean birth is not necessarily required for GBS-positive clients as long as IV antibiotic prophylaxis is administered during labor to prevent transmission to the newborn.Choice B rationaleIV antibiotic prophylaxis, typically with penicillin or ampicillin, is given to GBS-positive clients during labor to prevent neonatal GBS infection.Choice C rationaleObtaining a vaginal culture at 39 weeks of gestation is not necessary if the client was already screened and found positive for GBS at 36 weeks.Choice D rationaleMetronidazole is used to treat bacterial vaginosis or trichomoniasis, not GBS infection; thus, it is not appropriate for this scenario. .
