With regard to the use of IUDs (intrauterine devices), nurses should be aware that:

IUDs offer protection against sexually transmitted infections (STIs) and human immunodeficiency virus (HIV).

IUDs containing copper (Paragard) can provide an emergency contraception option if inserted within a few days of unprotected intercourse.

IUDs lower a woman's risk for pelvic inflammatory disease.

All IUDs provide protection from pregnancy for eight years.
