Answer to Question 1

ANS: D
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.

Answer to Question 2

ANS: A
Assessment of fundal height provides an estimation of gestational age in relationship to uterine size. Fundal height is measured by placing the end of a tape measure at the symphysis pubis and extending it to the fundus (Fig. 19.2). The uterus is usually palpable above the symphysis at 12 weeks of gestation, midway between the symphysis pubis and umbilicus at 16 weeks, and at the umbilicus at 20 weeks.
