Which of the following third generation cephalosporins is known for covering Pseudomonas?

Ceftazidime is recognized as a third-generation cephalosporin that has specific activity against Pseudomonas aeruginosa, a common and challenging pathogen often associated with serious infections, particularly in immunocompromised patients or those with chronic lung diseases. Ceftazidime's ability to penetrate the outer membrane of Pseudomonas and its stability against certain beta-lactamases contribute to its effectiveness in managing infections caused by this organism.

In contrast, the other options listed—such as Cefepime, though also effective against Pseudomonas, is classified as a fourth-generation cephalosporin. Cefdinir and Cefuroxime do not have notable activity against Pseudomonas and are primarily used for other types of infections. This distinction underscores the importance of understanding the spectrum of activity of various cephalosporins in clinical practice, especially when treating serious bacteria like Pseudomonas.
