In cephalosporins, the term generation refers to

• A. Spectrum of bacterial coverage
• B. Route of administration
• C. Cost
• D. Molecular weight

Answer: (A)

Generations in cephalosporins reflect the antibacterial spectrum and related properties of the drugs. As you move to later generations, cephalosporins typically gain broader activity against gram-negative bacteria and improved stability to certain beta-lactamases, while their activity against some gram-positive organisms shifts in different ways. The label is about what bacteria are likely to be inhibited, not about how the drug is given, how much it costs, or its molecular weight. So this item is testing understanding that the generation designation specifically describes the spectrum of bacterial coverage.
