A nurse is caring for a client with a bacterial respiratory tract infection who is receiving azithromycin (Zithromax).
Which of the following actions should the nurse take? (Select all that apply.)

Ceftriaxone (Rocephin) is athird-generation cephalosporin antibioticthat works byinterfering with the formation of bacterial cell walls.It is effective againstgram-negative bacteria, such asNeisseria gonorrhoeaeandHaemophilus species, which are common causes of bacterial meningitis.

Choice A is wrong because ceftriaxone is less active againstgram-positive bacteria, such asStaphylococcusandStreptococcusspecies.

Choice C is wrong because ceftriaxone is not effective againstanaerobic bacteria, which are bacteria that do not require oxygen to grow.Anaerobic bacteria are usually treated withmetronidazoleorclindamycin.

Choice D is wrong because ceftriaxone can treat bothaerobicandanaerobicgram-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 areListeria monocytogenesandBacillus anthracis, which are resistant to ceftriaxone.

Choice A is correct because azithromycin can cause liver toxicity and hepatitis, so the nurse should monitor the client’s liver function tests.

Choice B is wrong because azithromycin can be taken with or without food.

Choice C is wrong because azithromycin does not interact with dairy products.

Choice D is correct because azithromycin can increase the risk of sunburn and photosensitivity, so the nurse should advise the client to use sunscreen and avoid excessive sun exposure.

Choice E is correct because azithromycin is a bacteriostatic antibiotic that requires the client to complete the full course of therapy to prevent bacterial resistance and recurrence of infection.
