Question

which of the following statements about intrauterine devices (iuds) is true?
multiple choice
iuds are highly effective at preventing pregnancy and require little maintenance after they are in place.
an iud can be purchased from a pharmacy and placed by a woman prior to intercourse.
iuds provide a permanent, irreversible form of contraception for women.
spermicide should be used with an iud.

Explanation:

IUDs are among the most effective contraceptives (over 99% efficacy) and require minimal maintenance post-insertion (e.g., checking strings periodically). They are not available over-the-counter (require professional insertion), are reversible (removed by a provider), and do not need spermicide for effectiveness.

Answer:

IUDs are highly effective at preventing pregnancy and require little maintenance after they are in place.
