Correct answer: D — Transvaginal ultrasound scan

Transvaginal ultrasound scan is the best answer because the vignette is testing Viability scan and the recommended approach is consistent with NICE NG126. The other tests may be useful in different pathways, but they would not be the most direct first investigation for this presentation. Specifically, Newborn bilirubin measurement; Urine culture; Serum prolactin; Full blood count would be suboptimal in this scenario. The first investigation should answer the immediate clinical question and follow the relevant UK pathway.
