How often should a woman in the early second trimester return for a follow-up visit?

• A. Every 2 weeks
• B. Every 4 weeks
• C. Every week
• D. Every 6 weeks

Answer: (B)

In the early second trimester, prenatal visits are typically scheduled about once a month. This frequency aligns with routine monitoring of maternal health (blood pressure, weight, urine) and fetal well-being (fetal heart rate, growth assessment) while allowing time for essential mid‑pregnancy screening, such as the anatomy ultrasound around 18–22 weeks and other labs. With stable pregnancies, monthly visits provide a practical cadence that catches emerging issues without unnecessary burden on the patient. More frequent visits would usually be reserved for risk factors or symptoms, and spaced-out visits (every six weeks) would risk missing important milestones. So the best choice is a follow-up about once every four weeks.
