A nurse is preparing to assess fetal heart tones for a client who is at 12 weeks of gestation. Which of the following actions should the nurse take?

A. At 12 weeks, the uterus is just above the symphysis pubis, so the fetal heart rate is best heard in this area. B. Leopold maneuvers are used later in pregnancy (after 20 weeks) to determine fetal position. C. The client should be in a supine or semi-Fowler's position for better access. D. Fundal height measurement is not necessary at 12 weeks, as it is typically used after 20 weeks.
