Correct answer: B — Arrange a 75 g oral glucose tolerance test

Arrange a 75 g oral glucose tolerance test is the best answer because the vignette is testing Gestational diabetes and the recommended approach is consistent with NICE NG3. The other tests may be useful in different pathways, but they would not be the most direct first investigation for this presentation. Specifically, Liver function tests and bile acids; Cardiotocography; Full blood count; Pelvic ultrasound would be suboptimal in this scenario. The first investigation should answer the immediate clinical question and follow the relevant UK pathway.
