A pregnant patient comes in for a routine checkup and mentions she drinks a few cups of wine daily. What should you do FIRST?

When a pregnant patient discloses a behavior that poses a direct risk to fetal health, patient education/counseling about that risk takes priority over routine clinical procedures. Oral prophylaxis (A) and restorations (B) are appropriate parts of her dental care, but they don't address the more urgent health risk she just disclosed, so they are not the correct 'first' step here.
