Question

question 27
an intrauterine device is used to:
a treat cancer.
b stimulate ovulation.
c prevent pregnancy.
d reduce heaviness of menstrual flow.

Explanation:

An intrauterine device (IUD) is a form of contraception. It is inserted into the uterus to prevent pregnancy. It does not treat cancer (A is incorrect), stimulate ovulation (B is incorrect - in fact, some IUDs may affect ovulation in a way that helps prevent pregnancy), and while some hormonal IUDs may reduce menstrual flow, the primary function is contraception. So the key point is that its main use is pregnancy prevention.

Answer:

C. prevent pregnancy.
