Commonly prescribed antimicrobial agents ( 5 Questions)
A nurse is preparing to administer ceftriaxone (Rocephin) to a client who has bacterial meningitis.
The nurse should recognize that this medication is effective against which type of bacteria?
Choice A is wrong because ceftriaxone is less active against gram-positive bacteria, such as Staphylococcus and Streptococcus species.
Ceftriaxone (Rocephin) is a third-generation cephalosporin antibiotic that works by interfering with the formation of bacterial cell walls. It is effective against gram-negative bacteria, such as Neisseria gonorrhoeae and Haemophilus species, which are common causes of bacterial meningitis.
Choice C is wrong because ceftriaxone is not effective against anaerobic bacteria, which are bacteria that do not require oxygen to grow. Anaerobic bacteria are usually treated with metronidazole or clindamycin.
Choice D is wrong because ceftriaxone can treat both aerobic and anaerobic gram-negative bacteria, but not all aerobic bacteria are gram-negative.
Aerobic bacteria are bacteria that require oxygen to grow. Some examples of aerobic gram-positive bacteria are Listeria monocytogenes and Bacillus anthracis, which are resistant to ceftriaxone.
