Correct answer: B — Bladder diary and urinalysis
Bladder diary and urinalysis is the best answer because the vignette is testing Mixed urinary incontinence and the recommended approach is consistent with NICE NG123. The other tests may be useful in different pathways, but they would not be the most direct first investigation for this presentation. Specifically, Serum hCG repeated after 48 hours; Serum CA125; Pelvic ultrasound; Serum prolactin would be suboptimal in this scenario. The first investigation should answer the immediate clinical question and follow the relevant UK pathway.
