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 B

Explanation

Each of the five variables in a biophysical profile (BPP) is assigned a score of either 0 or 2 points, depending on whether it meets the criteria or not.

The five variables are:

Fetal breathing: 2 points if there is at least one episode of rhythmic breathing lasting at least 30 seconds within 30 minutes, 0 points otherwise.

Fetal movement: 2 points if there are at least three discrete body or limb movements within 30 minutes, 0 points otherwise.

Fetal tone: 2 points if there is at least one episode of extremity extension and subsequent return to flexion, 0 points otherwise.

Amniotic fluid volume: 2 points if there is a pocket of amniotic fluid measuring at least 2 cm in two perpendicular planes, 0 points otherwise.

Nonstress test: 2 points if there are at least two accelerations of fetal heart rate with or without fetal movement within 20 minutes, 0 points otherwise.

Choice A is wrong because each variable can have a score of either 0 or 2, not 0 or.

Choice C is wrong because there is no score of 1 for any variable.

Choice D is wrong because it is incomplete and does not provide the full range of possible scores.

A. To measure the fetal heart rate (FHR) in response to fetal movements. B. To monitor the uterine contractions. C. To indicate adequate fetal oxygenation and normal fetal neurological function. D. To assess fetal well-being and identify fetal hypoxia or distress.

Correct Answer is A

Explanation

To measure the fetal heart rate (FHR) in response to fetal movements.

This is because the FHR should increase by at least 15 beats per minute for at least 15 seconds when the fetus moves, which indicates a healthy and reactive fetus.

This is called an acceleration.

Choice B is wrong because the uterine contractions are not related to the fetal movements or the button pressing.

The uterine contractions are measured by a tocodynamometer or an intrauterine pressure catheter.

Choice C is wrong because the fetal oxygenation and neurological function are not directly measured by the button pressing.

The fetal oxygenation can be assessed by the FHR variability and decelerations, while the neurological function can be evaluated by other tests such as biophysical profile or fetal acoustic stimulation.

Choice D is wrong because the fetal well-being and hypoxia or distress are not indicated by the button pressing alone.

The fetal well-being and hypoxia or distress are determined by the FHR patterns, such as baseline, variability, accelerations and decelerations.
