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
A contraction stress test (CST) is performed near the end of pregnancy to determine how well the fetus will cope with the contractions of childbirth.
The aim is to induce contractions and monitor the fetus to check for heart rate abnormalities using a cardiotocograph.
A normal heartbeat is a good sign that the fetus will be healthy during labor.
Choice B is wrong because a CST does not measure maternal blood pressure.
Choice C is wrong because a CST does not assess placental function directly.
Choice D is wrong because a CST does not measure amniotic fluid volume.
Normal ranges for fetal heart rate are between 110 and 160 beats per minute.
Normal ranges for uterine contractions are between 2 and 5 contractions in 10 minutes, lasting less than 90 seconds each.
Correct Answer is C
Explanation
The level of AFP in a pregnant woman’s blood depends on how far along she is in her pregnancy.
AFP levels are normally high in the early weeks of pregnancy and then decline as the pregnancy progresses.
If the AFP level is too high or too low for the gestational age, it may indicate a problem with the baby’s development.
Choice A is wrong because maternal weight does not affect AFP levels.
Choice B is wrong because fetal heart rate does not affect AFP levels.
Choice D is wrong because the placental function does not affect AFP levels directly, but it may affect the levels of other hormones that are measured along with AFP in a quad screen.
