A 28-year-old nulliparous woman attends the family planning clinic requesting long-acting reversible contraception. She has no contraindications to hormonal methods. On examination, her uterus is normal size with no masses. She asks about both copper and hormonal IUCDs. After counselling on efficacy, side effects, and insertion technique, she chooses a levonorgestrel-releasing IUCD (LNG-IUD). What is the most appropriate immediate next step?

Explanation

## Management of LNG-IUD Insertion in Nulliparous Women ### The Correct Immediate Next Step **Key Point:** The stem explicitly states the patient has already been counselled on efficacy, side effects, and insertion technique. The most appropriate **immediate next step** is therefore to **obtain written informed consent and proceed with insertion**, provided pregnancy is excluded — which can be done at any time in the cycle. **High-Yield:** Option D correctly captures the complete immediate next step: informed consent + insertion at any time in the cycle if pregnancy is excluded. Option A (urine pregnancy test alone) is incomplete — it omits the essential step of obtaining written informed consent before any invasive procedure, and stopping at "proceed with insertion if negative" does not reflect the full clinical protocol. ### Why Option D is Correct Per WHO Medical Eligibility Criteria (MEC) and FSRH guidelines: - **Informed consent** is a mandatory prerequisite for any invasive procedure, including IUCD insertion. - **Pregnancy exclusion** is required but can be achieved by clinical history, last menstrual period assessment, or urine β-hCG — and insertion can proceed at **any time in the cycle** once pregnancy is confidently excluded. - The combination of consent + insertion (with pregnancy excluded) is the complete, appropriate next step after counselling. ### Why the Other Options Are Incorrect | Option | Issue | |--------|-------| | **A** | Incomplete — omits written informed consent, which is mandatory before insertion; also implies UPT is the only method of pregnancy exclusion | | **B** | Transvaginal ultrasound to measure cavity length is NOT routine for a clinically normal uterus; adds cost and delay without evidence of benefit (FSRH, 2023) | | **C** | Prophylactic antibiotics are NOT routinely recommended for IUCD insertion in low-risk women (WHO, FSRH); day 7 timing is not mandatory | ### Clinical Pearl **LNG-IUD in nulliparous women:** Modern FSRH and WHO guidelines support insertion at any time in the cycle if pregnancy is excluded. Insertion during menstruation may ease cervical access but is not mandatory. Expulsion rates and efficacy are comparable to multiparous women. The device is >99% effective and fully reversible. **Key Point (Harrison's / FSRH 2023):** Informed consent is a non-negotiable legal and ethical prerequisite before any invasive contraceptive procedure. A question asking for the "most appropriate immediate next step" after counselling must include consent as part of the answer — making Option D the most complete and correct response.
