A client with acquired immunodeficiency syndrome (AIDS) is prescribed zidovudine (azidothymidine, AZT [retrovir]), 200mg PO every 4 hours. When teaching the client about this drug, the nurse should provide which instruction?
Correct Answer: C
Rationale: Zidovudine (AZT) is an antiretroviral drug used to treat HIV infection, including in AIDS patients. It is important to follow the prescribed dosing schedule to maintain consistent drug levels in the body and effectively control the HIV virus. Taking zidovudine every 4 hours around the clock helps ensure the medication's therapeutic effects are maintained throughout the day. It is crucial for the client to adhere to the prescribed dosing regimen to prevent the development of drug resistance and to achieve the best treatment outcomes. Taking zidovudine with meals, on an empty stomach, or taking over-the-counter drugs for minor adverse reactions are not the correct instructions related to the dosing schedule of zidovudine.
