A nurse in a prenatal clinic is caring for a client who is suspected of having a hydatidiform mole. Which of the following findings should the nurse expect to observe in this client?

A. Rapid decline in human chorionic gonadotropin (hCG) levels: In hydatidiform mole, hCG levels are abnormally elevated and usually remain high or increase, not decline rapidly. Persistently high hCG is a key diagnostic indicator of molar pregnancy. B. Profuse, clear vaginal discharge: Vaginal discharge in molar pregnancy is typically described as dark brown or bright red bleeding rather than clear discharge, often described as "prune juice" consistency due to necrotic tissue. C. Irregular fetal heart rate: Since a hydatidiform mole usually involves abnormal placental tissue without a viable fetus, a fetal heart rate is generally absent. Irregular FHR would not be expected because there is often no fetus. D. Excessive uterine enlargement: The uterus often enlarges more rapidly and is larger than expected for gestational age due to the abnormal trophoblastic proliferation in a molar pregnancy. This is a classic sign and important clinical finding.
