A nurse is caring for a client who is in labor and has a diagnosis of group B streptococcus B-hemolytic infection.Which of the following medications should the nurse plan to administer?

Choice A rationaleAmpicillin is the drug of choice for group B streptococcus B-hemolytic infections. It effectively targets the bacterial pathogen, preventing neonatal infections during labor when administered intravenously.Choice B rationaleAzithromycin is ineffective against group B streptococcus. It is primarily used for atypical bacterial infections, including chlamydia and Mycoplasma, and is not indicated in this specific clinical scenario.Choice C rationaleCeftriaxone, a third-generation cephalosporin, is not the preferred first-line agent for group B streptococcus. Alternative antibiotics are chosen only in cases of documented penicillin allergy.Choice D rationaleAcyclovir is an antiviral agent used for herpes simplex virus infections. It has no antibacterial activity and is not indicated for group B streptococcus infections.
