Correct answer: D — Arrange postpartum oral glucose tolerance testing at six weeks

Explanation lettering: E = shown as A · D = shown as B · B = shown as C · A = shown as D · C = shown as E

A is correct. Diabetes Canada recommends a 75 g oral glucose tolerance test between 6 weeks and 6 months postpartum because fasting glucose or early HbA1c alone can miss persistent dysglycaemia. B omits the required postpartum assessment. C uses HbA1c too early and as an insensitive sole test. D continues insulin without hyperglycaemia. E ignores the substantial future risk of type 2 diabetes. Normal postpartum testing is followed by screening every 1 to 3 years and counselling about recurrence and cardiometabolic risk.
