A nurse is reviewing the findings of a biophysical profile (BPP) for a client who is at 40 weeks of gestation.
The BPP score is 6 out of 10 points.
Which of the following components are included in this score? (Select all that apply.)
Fetal breathing movement
Fetal tone
Reactive fetal heart rate
Amniotic fluid volume
Fetal position
Correct Answer : A,B,C,D
The correct answer is choice A, B, C and D. These are the four components of a biophysical profile (BPP) that are scored as 2 (normal) or 0 (abnormal) based on ultrasound examination. The fifth component is the nonstress test (NST) that measures the fetal heart rate reactivity. A total score of 8 or 10 is normal, 6 is equivocal, and 4 or less is abnormal.
Choice E is wrong because fetal position is not a part of the BPP score. Fetal position is determined by ultrasound but it does not affect the score.
Normal ranges for each component are:
• Fetal breathing movement: One or more episodes of fetal breathing lasting at least 30 seconds within 30 minutes.
• Fetal tone: One or more episodes of active extension and flexion of a fetal extremity or opening and closing of the hand within 30 minutes.
• Reactive fetal heart rate: Two or more fetal heart rate accelerations that peak at least 15 beats per minute above the baseline and last at least 15 seconds from baseline to baseline during 20 minutes of observation.
• Amniotic fluid volume: A single deepest vertical pocket of amniotic fluid that measures at least 2 centimeters.
• Gross body movement: Three or more discrete body or limb movements within 30 minutes.

Correct Answer is B
Explanation
Negative CST.A negative CST means that the fetal heart rate does not slow down (decelerate) after a contraction, which indicates that the baby can tolerate the stress of labor.
This is a normal and reassuring result.
Choice A is wrong because a positive CST means that the fetal heart rate slows down and stays slow after more than half of the contractions, which indicates that the baby may be at risk for problems during labor.
This is an abnormal and concerning result.
Choice C is wrong because an unsatisfactory CST means that there are not enough contractions to produce a reliable result.
This may happen if the medication or nipple stimulation does not induce enough contractions, or if there are other factors that interfere with the test, such as maternal movement or fetal sleep.
Choice D is wrong because a suspicious CST means that the results are unclear or inconsistent.This may happen if the fetal heart rate slows down after some but not all of the contractions, or if there are other types of decelerations that are not clearly related to the contractions.
A suspicious CST may need to be repeated in a couple of days.
Correct Answer is D
Explanation
Notify the provider and prepare for delivery.Oligohydramnios is a condition where the amniotic fluid volume is less than expected for gestational age and it is associated with maternal and fetal complications.
The nonstress test (NST) is a method of fetal surveillance that measures the fetal heart rate response to fetal movement.A reactive NST is defined as at least two accelerations of 15 beats per minute or more above the baseline, lasting 15 seconds or more, within a 20-minute period.
A nonreactive NST indicates fetal hypoxia or acidosis and requires further evaluation.An acoustic stimulator can be used to elicit fetal movement and accelerations, but it should not be repeated more than once in a 10-minute period.
Therefore, choice A is wrong because repeating the acoustic stimulation after 1 minute is too soon and may cause fetal distress.
Choice B is wrong because documenting the finding as a nonreactive NST is not enough to address the situation.Choice C is wrong because performing a contraction stress test (CST) is contraindicated in oligohydramnios because it may cause umbilical cord compression and fetal compromise.
The CST involves inducing uterine contractions with oxytocin or nipple stimulation and monitoring the fetal heart rate for signs of intolerance.
A negative CST means that there
