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.

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.
Correct Answer is B
Explanation
This method can be used to induce uterine contractions during the test by stimulating the uterus with a hormone that causes contractions.
Oxytocin is also the hormone that naturally triggers labor contractions.
Choice A is wrong because nipple stimulation can also induce contractions, but it is not as reliable or controllable as oxytocin infusion.
Choice C is wrong because oral medications are not used to induce contractions during a CST.
Some medications may interfere with the test results or cause side effects.
Choice D is wrong because applying warm compresses to the abdomen does not induce contractions.
It may help with pain relief or relaxation, but it does not affect the uterus.
Normal ranges for uterine contractions during a CST are three contractions in 10 minutes, each lasting 40 to 60 seconds.
Normal ranges for fetal heart rate during a CST are 110 to 160 beats per minute, with no decelerations after contractions.
