A client's Alpha-fetoprotein Test (AFP) result is reported as 0.8 MoM.
What does this result suggest?
Normal level of AFP for the given gestational age.
High level of AFP indicating a neural tube defect.
Low level of AFP indicating a potential chromosomal abnormality.
Inconclusive result, requiring further evaluation.
The Correct Answer is A
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 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.
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.
