What is the factor noted in a client's antenatal history that presents the greatest potential for causing neonatal sepsis following delivery?

• A. History of substance abuse during this pregnancy
• B. A previous urinary tract infection
• C. Inadequate prenatal care
• D. Multiple gestation pregnancy

Answer: (A)

The factor in a client's antenatal history that presents the greatest potential for causing neonatal sepsis following delivery is a history of substance abuse during this pregnancy. Substance abuse can lead to various complications, including intrauterine infections, preterm birth, and low birth weight, all of which significantly increase the risk of infection in the newborn. Substances like opioids, cocaine, and alcohol can compromise the immune system and contribute to neonatal withdrawal syndromes, which further complicate the baby's ability to fight off infections after birth.

Additionally, substance abuse may result in poor nutrition, increased exposure to infections, and lack of adherence to prenatal care, all of which can have detrimental effects on both the mother and the newborn, raising the susceptibility of the neonate to infections such as sepsis. Thus, this history is a crucial factor in assessing the potential risks for the neonate after delivery.
