A nurse is reviewing the results of a Contraction Stress Test (CST) with a pregnant client.
What does an equivocal CST indicate?
Late decelerations of the FHR with less than 50% of contractions.
Late decelerations of the FHR with at least 50% of contractions.
No late decelerations of the FHR during contractions.
Variable decelerations of the FHR with or without contractions.
The Correct Answer is A
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.

Correct Answer is A
Explanation
Normal level of AFP for the given gestational age.
AFP is a protein that the liver makes when its cells are growing and dividing to make new cells.
It is normally high in unborn babies and drops very low after birth.
The AFP test measures the amount of AFP present in blood and can help diagnose certain types of cancer and check how well treatment is working.
It can also help detect some birth defects in pregnant women.
Choice B is wrong because high level of AFP indicating a neural tube defect.
Neural tube defects are abnormalities that affect the brain and spinal cord of the fetus.
They can cause spina bifida, which is a condition where the spine does not close properly.
High levels of AFP can be a sign of neural tube defects, but they can also be caused by other factors, such as multiple pregnancies, inaccurate dating of pregnancy, or fetal death.
Choice C is wrong because low level of AFP indicating a chromosomal abnormality.
Chromosomal abnormalities are genetic disorders that affect the number or structure of chromosomes in the fetus.
They can cause Down syndrome, which is a condition where the fetus has an extra copy of chromosome 212.
Low levels of AFP can be a sign of chromosomal abnormalities, but they can also be caused by other factors, such as inaccurate dating of pregnancy, fetal death, or maternal obesity.
Choice D is wrong because inconclusive result, requiring further evaluation.
An inconclusive result means that the AFP level is neither too high nor too low to indicate a problem with the fetus.
It does not necessarily mean that there is something wrong with the fetus, but it may require further testing to confirm or rule out any abnormalities.
Normal ranges for AFP levels vary depending on the gestational age and the laboratory that performs the test.
Generally, the normal range for AFP levels in pregnant
Correct Answer is B
Explanation
The correct answer is choice B. Monitor fetal heart rate.
This is because cramping and vaginal bleeding after amniocentesis are signs of possible complications such as miscarriage, preterm labor, or injury to the fetus.
Monitoring fetal heart rate can help assess the well-being of the fetus and detect any signs of distress.
Choice A is wrong because administering Rho(D) immunoglobulin is only necessary if the mother has Rh-negative blood and the baby has Rh-positive blood, which can cause Rh sensitization.
This is not given routinely to all women who have amniocentesis.
Choice C is wrong because assessing maternal vital signs is not the first priority when there is a risk of fetal compromise.
Maternal vital signs can be affected by many factors and are not specific indicators of fetal health.
Choice D is wrong because obtaining an order for an ultrasound exam is not the first action to take.
An ultrasound exam can help confirm the diagnosis of complications such as placental abruption or fetal demise, but it requires time and equipment that might delay immediate intervention.
Monitoring fetal heart rate can be done quickly and easily at the bedside.
