A nurse is caring for a client who is prescribed ciprofloxacin for bacteremia.What is the mechanism of action for this medication?

Choice A rationaleCiprofloxacin is a bactericidal antibiotic that works by inhibiting DNA gyrase, an enzyme necessary for DNA replication in bacteria. This prevents bacterial cells from replicating and ultimately leads to their death.Choice B rationaleCiprofloxacin does not accelerate bacterial growth; instead, it inhibits growth by preventing DNA replication.Choice C rationaleCiprofloxacin is not a diuretic. Diuretics work on the kidneys to increase urine production, but ciprofloxacin targets bacterial DNA replication.Choice D rationaleCiprofloxacin is not a beta-blocker and does not lower heart rate or blood pressure. Beta-blockers work by blocking beta-adrenergic receptors in the heart.
