Correct answer: A — Confirm maternal observations and discuss induction timing

Confirm maternal observations and discuss induction timing is the best answer because the vignette is testing Pre-labour rupture of membranes and the recommended approach is consistent with NICE NG235. The other tests may be useful in different pathways, but they would not be the most direct first investigation for this presentation. Specifically, Transvaginal ultrasound scan; High vaginal swab; Newborn bilirubin measurement; Thyroid function tests would be suboptimal in this scenario. The first investigation should answer the immediate clinical question and follow the relevant UK pathway.
