Correct answer: B — Offer gestational diabetes screening with glucose challenge/OGTT pathway according to local Canadian practice

Routine screening for gestational diabetes is typically performed at 24-28 weeks in Canadian prenatal care pathways. Glycosuria alone is neither sensitive nor specific enough to determine screening. Diagnosis then guides diet, glucose monitoring and medication if targets are not met.
