At the 24-week visit, a pregnant woman demonstrates a less than expected growth in uterine size, easily palpable fetus that can be outlined by the nurse, and absence of fetal ballottement. Nurse Clariver should recognize this is most likely related to the development of:
a. Hydramnios
b. Oligohydramnios
c. amniotic fluid embolism
d. macrosomia

Answer B. Oligohydramnios occurs when the amount of amniotic fluid is severely reduced. This would result in less than expected growth in the uterus, a fetus that is surrounded by so little amniotic fluid that it is easily palpated and outlined, and the fetus will not be palpable when the examiner does a vaginal exam and pushes against the cervix (ballottement).
