A client asks the nurse about the significance of Alpha-fetoprotein Test (AFP) results.

How should the nurse respond?

AFP results are diagnostic for fetal anomalies.

AFP results require further evaluation for confirmation.

AFP results can only detect neural tube defects.

AFP results are affected by maternal race and ethnicity.

Answer and Explanation

The Correct Answer is B

AFP is a screening tool that can indicate the possibility of certain fetal anomalies, such as neural tube defects, abdominal wall defects, or chromosomal abnormalities.

However, AFP results are not diagnostic and cannot confirm the presence or absence of these conditions.

Therefore, further tests, such as ultrasound or amniocentesis, are needed to verify the results.

Choice A is wrong because AFP results are not diagnostic for fetal anomalies.

They only indicate a risk level that needs to be confirmed by other tests.

Choice C is wrong because AFP results can detect not only neural tube defects, but also other fetal anomalies, such as abdominal wall defects or chromosomal abnormalities.

Choice D is wrong because AFP results are not affected by maternal race and ethnicity.

They are affected by maternal age, weight, diabetes, multiple gestation, and gestational age.

Correct Answer is A

Explanation

A Doppler ultrasound blood flow analysis measures the velocity of blood flow in the uterine and fetal vessels.

This test can help assess the fetal well-being and oxygenation in cases of intrauterine growth restriction (IUGR).

Choice B is wrong because the amount of amniotic fluid in the uterine cavity is measured by ultrasound, not Doppler.

Choice C is wrong because the pressure of blood flow in the umbilical cord is not directly measured by Doppler, but rather inferred from the resistance index or pulsatility index.

Choice D is wrong because the oxygen saturation level of fetal blood is not measured by Doppler, but rather by fetal scalp sampling or pulse oximetry.

A. 0 points. B. 1 point. C. 2 points. D. 3 points.

Correct Answer is C

Explanation

According to the ACOG guidelines on antepartum fetal surveillance, one of the components of the biophysical profile is fetal breathing movements, which are scored as 2 points if there is one or more episodes of rhythmic fetal breathing movements of 30 seconds or more within 30 minutes.

Choice A is wrong because 0 points are given for absent or no breathing episode for ≥30 seconds within a 30 minute observation period.

Choice B is wrong because there is no 1 point score for this variable.

Choice D is wrong because there is no 3 point score for this variable.

The maximum score for each variable is 2 points.
