A nurse is interpreting the results of a biophysical profile (BPP) for a client who is at 34 weeks of gestation.
The nurse should understand that each of the five variables is assigned a score of how many points?
0 or.
0 or.
1 or.
1 or.
The Correct Answer is B
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.

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.
Correct Answer is C
Explanation
. The client’s cervix is dilated.
This indicates that the client may be in preterm labor, which is a contraindication for amniocentesis.
Amniocentesis is a procedure that involves inserting a needle into the amniotic sac to obtain a sample of amniotic fluid for genetic testing or other purposes.
It is usually performed between 15 and 20 weeks of gestation.
Choice A is wrong because the client’s bladder should be full for amniocentesis.
This helps to push the uterus upward and away from the bladder, reducing the risk of injury and making it easier to visualize the fetus and the needle.
Choice B is wrong because the client’s uterus should be above the symphysis pubis at 16 weeks of gestation.
This is a normal finding and does not affect the procedure.
Choice D is wrong because the client’s fundal height should measure around 16 cm at 16 weeks of gestation.
A fundal height of 20 cm may indicate a large for gestational age fetus, multiple gestation, or polyhydramnios (excess amniotic fluid), but these are not absolute contraindications for amniocentesis.
However, they may require further evaluation and adjustment of the technique.
