Question 1 of 5
A nurse is caring for a client who is prescribed ciprofloxacin for bacteremia. What is the mechanism of action for this medication?
Correct Answer: A
Rationale: The correct answer is A. Ciprofloxacin is a fluoroquinolone antibiotic that works by inhibiting the enzyme DNA gyrase, which is essential for bacterial DNA replication. By inhibiting this enzyme, ciprofloxacin is bactericidal, meaning it kills the bacteria. This mechanism of action specifically targets bacterial DNA replication, leading to the disruption of bacterial growth and ultimately killing the bacteria.
Choices B, C, and D are incorrect:
B: This medication does not accelerate bacterial growth; it actually inhibits bacterial growth.
C: Ciprofloxacin is not a diuretic that works on the distal tubule of the nephron; it is an antibiotic.
D: Ciprofloxacin is not a beta-blocker that blocks beta-2 receptors; it is an antibiotic with a different mechanism of action.
