Correct answer: B — Offer gestational diabetes screening using the local Canadian pathway at 24 to 28 weeks

Offer gestational diabetes screening using the local Canadian pathway at 24 to 28 weeks is the single best answer because the age, timing, examination findings and investigations in the vignette fit Gestational diabetes screening better than the alternatives. The most tempting distractor is less appropriate because it either treats a neighbouring presentation, delays a time-critical intervention, or ignores a key discriminator in the stem. The remaining options are suboptimal because they would miss the diagnosis, use an investigation or treatment in the wrong sequence, or fail to address safety and follow-up. Canadian practice should be anchored to Diabetes Canada CPG, with attention to acuity, safety-netting and local provincial pathways.
