A nurse admits a client in early labor. As part of the admission assessment, the nurse reviews the prenatal record and conducts an interview. Why is it critical for the nurse to verify the client's Group B Streptococcus (GBS) status and other prenatal data during this phase?

A. Pain management is an important aspect of labor care, but it is unrelated to prenatal laboratory findings such as GBS status. Analgesia decisions are based on the client’s preferences and progress in labor, not infection screening results. B. The time of membrane rupture is important for infection risk assessment but is obtained through the client’s history, not from prenatal data. It does not determine antibiotic need unless GBS positivity or prolonged rupture is documented. C. Verifying GBS status ensures that infected or colonized clients receive intrapartum antibiotics, typically penicillin, to prevent neonatal sepsis, pneumonia, or meningitis. Reviewing prenatal labs helps guide timely prophylactic treatment and reduces neonatal morbidity. D. Cesarean delivery decisions are based on obstetric indications such as fetal distress or failure to progress, not GBS status. GBS colonization alone is not a reason for cesarean section and is managed effectively with intrapartum antibiotics.
