The nurse practitioner is informing a pregnant adolescent in her first trimester about the frequency of prenatal visits. The NP instructs her to return:

Rationale: A. Visits every 2 weeks until 16 weeks are not standard; early prenatal visits are generally spaced slightly farther apart unless high-risk conditions exist. B. Prenatal visits are typically scheduled every 4 weeks until 28 weeks’ gestation for a healthy, low-risk pregnancy. These visits monitor maternal and fetal health, provide education, and identify potential complications early. C. Between 28 and 36 weeks, visits usually occur every 2 weeks, not every 4 weeks. D. After 36 weeks, visits are generally weekly to closely monitor maternal and fetal well-being before delivery.
