Q2:
B. Her husband has not been treated.

You need to ask the patient if her husband was treated each time she took therapy. When she was asked about this, she replied that she was given a treatment for her husband to take, but she found the medicine so unpleasant to take that she wanted to spare him the discomfort and never gave it to him.

Trichomoniasis is a sexually-transmitted disease and there is no immunity after infection. Males can become colonized with this organism, but they are almost always asymptomatic. Nevertheless, male sexual partners should be treated simultaneously with infected females to avoid reinfection of the female partner. The husband in this case should take a course of treatment at the same time his wife takes it. In addition, trichomoniasis is an STD, and it is likely the he has also had contact with someone outside of the marriage who is infected. It is his obligation to inform that individual as well. The patient and her husband should be counseled about the nature of this infection, their risk of other STDs while having unprotected sex outside of the marriage, and they were offered the opportunity to be tested for HIV.
