One of your patients, Z.K., a 33-year-old biology professor, has just begun therapy with lamivudine/ zidovudine (Combivir) for a human immunodeficiency virus (HIV) infection. She has many questions about this medication therapy, and you are meeting with her to review her questions. 1. Z.K. asks you why there are two drugs in this particular medication. What is your explanation? 2. While she is receiving this drug therapy, Z.K. is continually monitored for what potential major problem? 3. What will be done to monitor for this problem, and how is it manifested? 4. Develop a patient teaching guide for Z.K., emphasizing any specific cautions and symptoms to report to the health care provider.
