A nurse is caring for a client who has bacterial vaginosis. Which of the following medications should the nurse expect the provider to prescribe?

Rationale: A. Metronidazole: This is the treatment of choice for bacterial vaginosis because it effectively targets anaerobic bacteria such as Gardnerella vaginalis, the main causative organism. B. Doxycycline: This antibiotic is primarily used to treat Chlamydia trachomatis infections and is not effective for bacterial vaginosis. C. Azithromycin: This medication is effective for Chlamydia trachomatis and Mycoplasma genitalium infections, not for bacterial vaginosis caused by anaerobes. D. Acyclovir: This antiviral agent is used to treat herpes simplex virus infections and has no therapeutic effect against bacterial pathogens.
