Answer to Question 1

ANS: C
The EDD should be updated throughout the pregnancy for confirmation of dates by determining when quickening occurs, when fetal heart tone (FHTs) are first auscultated, when the fundal height is at the umbilicus, and, most accurately, through an ultrasound estimation at 16 to 20 weeks.

Answer to Question 2

ANS: C
Monitoring FHR is a vital component of fetal surveillance, as it provides important information on placental function, fetal hypoxia, and whether the intrauterine environment can support and sustain the fetus. The FHR can usually be auscultated as early as 10 weeks with an electronic Doppler and by 16 to 19 weeks with careful assessment and fetoscope (Cunningham et al., 2010). A normal FHR is 120 to 160 beats per minute. A sustained FHR of below 100 beats per minute is indicative of fetal jeopardy. If there is a question of whether the FHR is being adequately evaluated, the maternal pulse should simultaneously be assessed to ensure that the FHR, not the maternal heart rate, is actually being auscultated.
