A community health nurse is determining available and needed supplies in the event of a bioterrorism attack. The nurse should be aware that community members exposed to anthrax will need access to which medication?

• A. Metronidazole
• B. Ciprofloxacin
• C. Zanamivir
• D. Fluconazole

Answer: (B)

When someone is exposed to anthrax, the immediate goal is to prevent the bacteria from causing illness by giving an antibiotic that covers Bacillus anthracis. Ciprofloxacin is a fluoroquinolone that is effective against anthrax and is the standard choice for post-exposure prophylaxis and early treatment in this context. Providing this medication helps interrupt the infection during the incubation period, which can last up to about two months, hence the need for a prolonged supply. The other drugs listed target different organisms—metronidazole for anaerobic bacteria, zanamivir for influenza, and fluconazole for fungal infections—so they wouldn’t prevent anthrax illness after exposure. In community planning, ensuring access to ciprofloxacin for exposed individuals is essential to reduce the risk of developing inhalational anthrax.
