Question: 1 / 1820

Ceftaroline is notable for its activity against which type of bacteria?

Pseudomonas aeruginosa

MSSA

MRSA

Ceftaroline is notable for its activity against MRSA (Methicillin-Resistant Staphylococcus Aureus). This antibiotic is a fifth-generation cephalosporin that exhibits excellent activity against a broad range of Gram-positive organisms, including MRSA. Ceftaroline is not effective against Pseudomonas aeruginosa (Choice A), which is typically treated with antibiotics like ciprofloxacin or piperacillin-tazobactam. While ceftaroline is effective against MRSA (Choice C) and MSSA (Choice B), it is specifically praised for its activity against MRSA infections. Finally, the term "B-lactams" (Choice D) is a class of antibiotics that includes cephalosporins like ceftaroline, but this choice is not as specific as Choice C in highlighting ceftaroline's notable activity.
