Correct answer: A — Ruptured ectopic pregnancy

Early pregnancy with unilateral pain, bleeding, dizziness, tachycardia and hypotension is most concerning for ruptured ectopic pregnancy. Threatened miscarriage would not usually cause haemodynamic compromise. Cystitis and round ligament pain do not fit the bleeding and shock features. The pearl is that a positive pregnancy test plus abdominal pain is ectopic until safely excluded.
