A nurse is caring for a client who has oligohydramnios and is undergoing a biophysical profile (BPP).
The nurse should expect to see which of the following findings on the ultrasound?
An amniotic fluid index (AFI) of 8 cm
An amniotic fluid index (AFI) of 4 cm
A single vertical pocket of amniotic fluid measuring 3 cm
A single vertical pocket of amniotic fluid measuring 5 cm
The Correct Answer is B
An amniotic fluid index (AFI) of 4 cm indicates oligohydramnios, which is a low amount of amniotic fluid.
Oligohydramnios can be caused by various factors, such as uteroplacental insufficiency, rupture of membranes, postterm pregnancy, fetal anomalies, or certain medications.
Oligohydramnios can lead to complications such as fetal death, intrauterine growth restriction, limb contractures, or delayed lung maturation.
Choice A is wrong because an AFI of 8 cm is within the normal range for amniotic fluid volume.
Choice C is wrong because a single vertical pocket of amniotic fluid measuring 3 cm is also within the normal range for amniotic fluid volume.
Choice D is wrong because a single vertical pocket of amniotic fluid measuring 5 cm is also within the normal range for amniotic fluid volume.
Normal ranges for AFI and single vertical pocket are > 5 to < 24 cm and ≥ 2 to < 8 cm, respectively.

Explanation
An amniotic fluid index (AFI) of 4 cm indicates oligohydramnios, which is a low amount of amniotic fluid.
Oligohydramnios can be caused by various factors, such as uteroplacental insufficiency, rupture of membranes, postterm pregnancy, fetal anomalies, or certain medications.
Oligohydramnios can lead to complications such as fetal death, intrauterine growth restriction, limb contractures, or delayed lung maturation.
Choice A is wrong because an AFI of 8 cm is within the normal range for amniotic fluid volume.
Choice C is wrong because a single vertical pocket of amniotic fluid measuring 3 cm is also within the normal range for amniotic fluid volume.
Choice D is wrong because a single vertical pocket of amniotic fluid measuring 5 cm is also within the normal range for amniotic fluid volume.
Normal ranges for AFI and single vertical pocket are > 5 to < 24 cm and ≥ 2 to < 8 cm, respectively.
Correct Answer is A
Explanation
This result suggests that the baby has a low risk of having a genetic disorder or a neural tube defect.
Choice B is wrong because a high level of AFP indicating a neural tube defect would be greater than 2 MoM.
Choice C is wrong because a low level of AFP indicating a potential chromosomal abnormality would be less than 0.5 MoM.
Choice D is wrong because an inconclusive result, requiring further evaluation, would depend on other factors such as ultrasound findings and maternal age.
MoM stands for multiples of the median, which is a way of comparing the AFP level of a pregnant person to the average level for their gestational age.
Values between 0.5 and 2.49 MoM are considered normal.
