What is a characteristic of cefepime?

Cefepime is known for its broad-spectrum activity, particularly against Gram-negative bacteria, and it is classified as a fourth-generation cephalosporin. One of its distinguishing features is its excellent effectiveness against Pseudomonas aeruginosa, making it a preferred choice in treating infections caused by this organism, which is often resistant to many other antibiotics.

This characteristic is particularly important in hospital settings, where Pseudomonas is a common cause of nosocomial infections, and cefepime's extended spectrum makes it a useful option in cases requiring strong coverage against resistant organisms.

In contrast, the other choices do not accurately reflect cefepime's properties. It isn't a first-generation cephalosporin, as that classification pertains to older cephalosporins with narrower spectra. Additionally, while cefepime can be used for outpatient infections, it is more commonly administered in inpatient settings for more severe or resistant infections. Lastly, cefepime is quite effective against various nosocomial infections, particularly those caused by Pseudomonas, adding to its utility within hospitals.
