A nurse is discussing the factors that can affect Alpha-fetoprotein Test (AFP) results with a pregnant client.

Which factor should the nurse mention?

Maternal weight.

Fetal heart rate.

Gestational age.

Placental function.

Answer and Explanation

The Correct Answer is C

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.

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.

A. Late decelerations of the FHR with less than 50% of contractions. B. Late decelerations of the FHR with at least 50% of contractions. C. No late decelerations of the FHR during contractions. D. Variable decelerations of the FHR with or without contractions.

Correct Answer is A

Explanation

An equivocal CST indicates late decelerations of the FHR with less than 50% of contractions.

This means that the fetus may have some degree of hypoxia or distress, but not enough to warrant immediate delivery.

An equivocal CST may also result from hyperstimulation of the uterus, which can cause excessive contractions and reduce blood flow to the placenta.

Choice B is wrong because late decelerations of the FHR with at least 50% of contractions is a positive CST, which indicates a high risk of fetal death due to hypoxia and is a contraindication to labor.

Choice C is wrong because no late decelerations of the FHR during contractions is a negative CST, which indicates a good fetal wellbeing and tolerance of labor.

Choice D is wrong because variable decelerations of the FHR with or without contractions are not related to uterine activity and may indicate cord compression or other fetal problems.

Variable decelerations are not used to interpret CST results.
