Final answer:
Women not receiving intrapartum antibiotic prophylaxis for GBS typically do not require routine antibiotics and should be monitored, with treatment provided if symptoms of infection arise.
Step-by-step explanation:
Women without an indication for intrapartum antibiotic prophylaxis (Abx PPx) for Group B Streptococcus (GBS) need not receive routine antibiotic treatment during labor. This is because GBS is commonly found in the vagina and gastrointestinal tract of healthy women and does not always lead to infection. The primary approach for these women is monitoring and supportive care unless signs of infection or other complications arise. Screening protocols for GBS help identify those who do require intrapartum antibiotic prophylaxis to prevent neonatal infections, which can lead to severe complications such as meningitis. For women not receiving GBS prophylaxis, it's important to maintain vigilant observation and provide immediate treatment if infection symptoms present in the mother or newborn.
