A nurse is discussing the mechanism of action of antibiotics with a patient. Which of the following statements best demonstrates a nurse's understanding of this concept?

A. Antibiotics work solely by interacting with receptors on bacterial cells: Antibiotics act through several mechanisms, not just receptor interaction. Some disrupt cell wall synthesis, others inhibit protein production or interfere with nucleic acid metabolism. B. All antibiotics have the same mechanism of action and therapeutic effects: Antibiotics differ widely in how they work and what infections they treat. Assuming uniform mechanisms ignores the diversity between classes such as beta-lactams, macrolides, and fluoroquinolones. C. Antibiotics can inhibit bacterial cell wall synthesis, protein synthesis, or DNA replication: This statement reflects the primary mechanisms of action of antibiotics. By targeting these vital bacterial processes, antibiotics effectively prevent bacterial growth or kill the organisms. D. The mechanism of action of antibiotics involves their chemical structure only: While chemical structure influences how a drug works, the mechanism of action is defined by its specific biological effect on bacteria, not just its molecular makeup.
