Final answer:
If the mom does NOT have a culture for Group B Streptococcus and goes into labor or has any risk factors, the appropriate action would be to administer broad-spectrum antibiotics (c).
Step-by-step explanation:
If the mom does NOT have a culture for Group B Streptococcus and goes into labor or has any risk factors, the appropriate action would be to administer broad-spectrum antibiotics (c). This is because Group B Streptococcus (GBS) is a common cause of neonatal meningitis, and without preventive measures, the baby could be at risk of infection during childbirth. Administering broad-spectrum antibiotics can help prevent the transmission of GBS from the mother to the baby and reduce the incidence of early onset neonatal meningitis.
