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

Choice A rationale: Screening for sexually transmitted infections (STIs) prior to IUD placement is essential to reduce the risk of pelvic inflammatory disease (PID). The insertion process can introduce bacteria from the cervix or vagina into the uterine cavity, increasing infection risk if an STI is present. Guidelines recommend screening high-risk patients or those with recent STI history. Identifying infections before insertion allows treatment, preventing serious reproductive complications, including infertility. Choice B rationale: Most intrauterine devices (IUDs) have a lifespan longer than 2 years; copper IUDs last up to 10 years, and hormonal IUDs typically last between 3 and 7 years depending on the type. Replacing the device every 2 years is unnecessary and not evidence-based. Premature removal or replacement increases risk of procedure-related complications without added contraceptive benefit. Choice C rationale: Irregular spotting or breakthrough bleeding during the first few months after IUD insertion is common due to endometrial adjustment to the foreign body and hormonal changes (for hormonal IUDs). This occurs as the endometrial lining remodels, and bleeding usually decreases with time. Patient education about this transient effect improves adherence and reduces anxiety related to unexpected bleeding. Choice D rationale: There is no contraindication to tampon use while an IUD is in place. Tampons do not interfere with IUD function or position. Although some clinicians advise caution initially post-insertion to prevent infection, scientific evidence does not support a permanent restriction on tampon use during menstruation after proper healing. Choice E rationale: Signing informed consent before IUD insertion is legally and ethically required. It ensures the client understands benefits, risks, potential complications (such as expulsion or perforation), and alternative contraceptive methods. This process protects patient autonomy and supports shared decision-making, critical components of safe clinical practice.
