A client's CST result is interpreted as equivocal.

What additional diagnostic test may be recommended to further evaluate fetal well-being?

Non-stress test (NST)

Amniocentesis.

Magnetic resonance imaging (MRI).

Chorionic villus sampling (CVS).

Answer and Explanation

The Correct Answer is A

An NST is a test that measures the fetal heart rate in response to fetal movement.

It is a non-invasive and simple way to assess fetal well-being.

An NST may be recommended to further evaluate fetal well-being if the CST result is equivocal, meaning that occasional but not persistent late decelerations are present.

Choice B. Amniocentesis is wrong because it is an invasive procedure that involves inserting a needle into the uterus to collect amniotic fluid for genetic testing or fetal lung maturity.

It is not used to evaluate fetal well-being in response to contractions.

Choice C. Magnetic resonance imaging (MRI) is wrong because it is an imaging technique that uses magnetic fields to create detailed pictures of the fetus and the placenta.

It is not used to evaluate fetal well-being in response to contractions.

Choice D. Chorionic villus sampling (CVS) is wrong because it is an invasive procedure that involves inserting a catheter or a needle into the placenta to collect chorionic villi for genetic testing.

It is not used to evaluate fetal well-being in response to contractions.

Normal ranges for CST are negative (normal) or positive (abnormal).

Equivocal and unsatisfactory are special categories of test outcomes that require further testing.

Normal ranges for NST are reactive (reassuring) or non-reactive (non-reassuring).

Correct Answer is A

Explanation

This is because AFP levels vary according to the gestational age of the fetus, and reporting them as multiples of the median (MoM) allows for a standardized comparison.

Choice B is wrong because AFP results do not differentiate between neural tube defects and chromosomal abnormalities.

They only indicate an increased risk for these conditions, which need further testing to confirm.

Choice C is wrong because AFP results do not assess the risk of fetal demise or multiple gestation.

They only measure the amount of AFP in the maternal blood, which can be affected by various factors such as maternal weight, race, diabetes, and fetal anomalies.

Choice D is wrong because AFP results are reported as MoM regardless of factors such as maternal weight and race.

These factors are taken into account when calculating the MoM value, which adjusts for the expected variation in AFP levels among different populations.

Normal ranges for AFP MoM vary depending on the laboratory and the method used, but generally they are between 0.5 and 2.52.

Values above or below this range may indicate an increased risk for certain fetal conditions or complications.

A. Preterm labor. B. Premature rupture of membranes. C. Infection. D. Bleeding.

Correct Answer is A

Explanation

A contraction stress test (CST) is a test that simulates labor contractions to see how the baby’s heart rate responds to the stress of uterine contractions.

The biggest risk of the test is that it may cause the pregnant person to go into labor before their due date.

Some possible explanations for the other choices are:

Choice B. Premature rupture of membranes.

This is a condition where the amniotic sac breaks before labor begins.

It can increase the risk of infection and cord prolapse, but it is not a direct complication of CST.

Choice C. Infection.

This is a possible risk of any invasive procedure, but CST is usually done with external fetal monitoring and oxytocin infusion, which do not require breaking the skin or entering the uterus.

Choice D. Bleeding.

This is a potential risk of CST for people who have placenta previa, a condition where the placenta covers the cervix and can detach during contractions.

However, CST is not recommended for people who have placenta previa or other conditions that increase the risk of uterine rupture or bleeding.
