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.)

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.

A rash is a possible adverse effect of cephalexin (Keflex), a type of antibiotic used to treat bacterial skin infections.A rash may indicate an allergic reaction to the medication, which can be serious and require immediate medical attention.

Choice A is wrong because diarrhea is a common side effect of cephalexin that usually does not need medical attention unless it is severe or watery.

Choice B is wrong because headache is not a common or serious side effect of cephalexin.

Choice D is wrong because nausea is a common side effect of cephalexin that usually does not need medical attention unless it is persistent or severe.
