During a prenatal visit, a nurse measures a client's fundal height at 19 cm. This measurement indicates that the fetus has reached approximately which gestational age?

Explanation:
Fundal height in centimeters roughly tracks gestational age in weeks once you’re past about 20 weeks. The uterus grows about 1 cm per week, so a measurement of 19 cm corresponds to about 19 weeks of gestation (roughly the end of the first half of pregnancy). Before 20 weeks, this relationship isn’t reliable, so this method isn’t used to date the pregnancy then.
