A client was exposed to anthrax. Which of the following antibiotics should the nurse plan to administer?
Correct Answer: A
Rationale: The correct answer is A: Ciprofloxacin. Anthrax is caused by the bacterium Bacillus anthracis, and ciprofloxacin is the recommended antibiotic for treating anthrax due to its effectiveness against this specific bacterium. Ciprofloxacin works by inhibiting bacterial DNA replication, thus stopping the growth and spread of the anthrax bacteria.
The other choices are incorrect because:
B: Fluconazole is an antifungal medication and is not effective against bacterial infections like anthrax.
C: Tobramycin is an antibiotic primarily used to treat bacterial infections in the eyes, ears, and skin, but it is not the first-line treatment for anthrax.
D: Vancomycin is an antibiotic used to treat certain bacterial infections, but it is not the preferred choice for anthrax treatment.
