A 25-year-old had unprotected sex 4 days ago. Which is the most effective emergency contraception?
Answer and explanation
Correct answer: B. A copper intrauterine device
- Step 1: Hormonal methods lose effect with time and with higher body weight. Step 2. A copper device can be inserted within 5 days and is the most effective, with continued contraception afterward. Answer: a copper IUD. Why not the others: the remaining options describe a different concept, measure or action and are not supported by Canadian guidance or law.
