Which of the following is NOT a characteristic of penicillinase-resistant penicillins? A) Include drugs like nafcillin, oxacillin, and dicloxacillin B) Effective against penicillinase-producing bacteria C) Used for treating infections caused by Staphylococcus aureus D) Have a broader spectrum of activity than penicillin G
Understand the Problem
The question is asking which statement does not correctly describe penicillinase-resistant penicillins. We need to analyze the options provided to identify the one that is inaccurate.
Answer
Penicillinase-resistant penicillins do not have a broader spectrum of activity than penicillin G.
The final answer is that penicillinase-resistant penicillins do not have a broader spectrum of activity than penicillin G.
Answer for screen readers
The final answer is that penicillinase-resistant penicillins do not have a broader spectrum of activity than penicillin G.
More Information
Penicillinase-resistant penicillins like nafcillin, oxacillin, and dicloxacillin are specifically designed to resist breakdown by penicillinase enzymes and are effective against penicillinase-producing Staphylococcus aureus. They do not have a broader spectrum compared to penicillin G, which remains effective against a wider range of organisms.
Tips
A common mistake is assuming that penicillinase-resistant penicillins must have a broader spectrum simply because they are resistant to certain bacterial enzymes.
