The 16-year-old is taking acyclovir. Which statement, if made by the adolescent, should indicate to the nurse that the medication is having the desired therapeutic effect?

A: A side effect of acyclovir is a change in the menstrual cycle; however, having a regular menstrual cycle is not the desired therapeutic effect. B: A bad odor from the vagina is a symptom of bacterial vaginosis or trichomoniasis vaginalis, and usually not a symptom of genital herpes simplex. C: Acyclovir (Zovirax), an antiviral medication, is indicated for the treatment of genital herpes simplex virus, shingles, or chicken pox. Labial sores are associated with genital herpes simplex. Improvement of labial sores indicates that acyclovir is having the desired therapeutic effect. D: A green vaginal discharge may be a symptom of Trichomonas, which is treated with metronidazole (Flagyl), an amebicide.
