Q

An unmarried young woman describes her sex life as “active” and involving “many” partners. She wants a contraceptive method that is reliable and does not interfere with sex. She requests an intrauterine device (IUD). Which information is most important for the nurse to share? a. “The IUD does not interfere with sex.” b. “The risk of pelvic inflammatory disease will be higher with the IUD.” c. “The IUD will protect you from sexually transmitted infections.” d. “Pregnancy rates are high with the IUD.”

A

ANS: B Disadvantages of IUDs include an increased risk of pelvic inflammatory disease (PID) in the first 20 days after insertion, as well as the risks of bacterial vaginosis and uterine perforation. The IUD offers no protection against sexually transmitted infections (STIs) or the human immunodeficiency virus (HIV), as does a barrier method. Because this woman has multiple sex partners, she is at higher risk of developing an STI. Stating that an IUD does not interfere with sex may be correct; however, it is not the most appropriate response. The typical failure rate of the IUD is approximately 1%.
