Final answer:
The treatment regimen for a patient testing positive for GBS is antibiotics during labor to reduce the risk of transmission to the newborn.
Step-by-step explanation:
The treatment for a patient who tests positive for Group B streptococcus (GBS) is antibiotics during labor. Antibiotics are administered to the mother during labor to reduce the risk of transmitting the bacteria to the newborn. This helps prevent neonatal meningitis, a serious infection that can occur in babies up to 3 months of age. The antibiotics used are typically intravenous penicillin or ampicillin plus gentamicin.
