Which finding is a contraindication for prescribing oral contraceptives?

The correct choice for a contraindication for prescribing oral contraceptives is the history of migraine headaches. In particular, migraines that are accompanied by aura can pose significant risks when using estrogen-containing contraceptives. Estrogen can increase the risk of thromboembolic events, such as stroke, particularly in individuals with a history of migraines with aura. Therefore, such patients are often advised against using combined oral contraceptives to avoid these potentially severe complications.

While hypertension and diabetes mellitus can also pose risks when prescribing oral contraceptives, they are not absolute contraindications. Women with controlled hypertension may still be prescribed hormonal contraceptives, and diabetes only contraindicates use in the presence of additional risk factors, such as vascular complications. The history of renal calculi can influence the choice of contraceptives, but it typically does not serve as a strict contraindication either.
