A nurse is providing client teaching regarding an intrauterine device (IUD). Which of the following statements should the nurse include in the teaching?

Choice A rationale Prior to IUD insertion, screening for sexually transmitted infections (STIs) is crucial to prevent the introduction of pathogens into the upper reproductive tract. An untreated STI, particularly chlamydia or gonorrhea, can lead to pelvic inflammatory disease (PID) when an IUD is placed, as the device might facilitate the ascent of bacteria. Choice B rationale The duration of effectiveness for intrauterine devices varies depending on the type. Hormonal IUDs typically last for 3 to 8 years, while copper IUDs can remain effective for up to 10 years. Therefore, the statement that the device must be replaced every 2 years is incorrect and misleading for most available IUDs. Choice C rationale Irregular spotting and changes in menstrual bleeding patterns are common side effects during the initial months following IUD placement, particularly with hormonal IUDs. This is due to the local endometrial effects of progesterone release or the inflammatory reaction induced by copper, as the uterus adapts to the foreign body. Choice D rationale There is no medical contraindication to using tampons with an IUD. The IUD resides in the uterus, while tampons are inserted into the vaginal canal. There is no physical interaction or risk of dislodgement of the IUD by tampon use. Clients can continue their preferred menstrual hygiene products. Choice E rationale Informed consent is a fundamental ethical and legal requirement before any medical procedure, including IUD insertion. The client must be provided with comprehensive information regarding the procedure, including its benefits, risks, alternatives, and potential side effects, to make an autonomous and voluntary decision.
