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

Answer and Explanation

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.

A. The fetus is in a breech presentation B. The fetus has not moved for 40 minutes. C. The baseline FHR variability is minimal. D. The client has a history of stillbirth. E. The test result is nonreactive after 40 minutes.

Correct Answer is ["E"]

Explanation

The test result is nonreactive after 40 minutes.Vibroacoustic stimulation (VAS) is the application of a vibratory sound stimulus to the abdomen of a pregnant woman to induce fetal heart rate (FHR) accelerations.VAS is typically used during a nonstress test (NST) to elicit fetal movement and reactivity when the baseline FHR variability is minimal or the test result is nonreactive after 40 minutes.VAS can shorten the testing time and reduce the incidence of non-reactive cardiotocography.

Choice A is wrong because the fetus’s presentation does not affect the use of VAS.

Choice B is wrong because VAS is not indicated for a fetus that has not moved for 40 minutes, unless the NST result is also nonreactive.

Choice C is wrong because minimal baseline FHR variability is not a sufficient indication for VAS, unless the NST result is also nonreactive.

Choice D is wrong because a history of stillbirth does not affect the use of VAS.

A nurse is interpreting the results of a contraction stress test (CST) for a client who is at 38 weeks of gestation. The nurse notes that there are no late or significant variable decelerations of the fetal heart rate (FHR). How should the nurse document this finding?

Correct Answer is B

Explanation

(Select all that apply) A nurse is performing a nonstress test (NST) for a client who is at 32 weeks of gestation and has gestational diabetes mellitus. The nurse uses vibroacoustic stimulation to elicit fetal movement and acceleration of FHR. What are the indications for using this method?

Correct Answer is ["E"]

Explanation

A nurse is providing discharge instructions to a client who had a nonreactive nonstress test (NST) followed by a biophysical profile (BPP) with a score of 8/10. Which of the following statements by the client indicates an understanding of the teaching?

A nurse is assessing a fetal heart rate (FHR) tracing for a client who is in active labor. The nurse notes that the baseline FHR is 150 bpm with absent variability and recurrent variable decelerations with slow return to baseline. What category of FHR tracing does this represent?

A nurse is caring for a client who is undergoing an oxytocin-stimulated contraction stress test (CST). The nurse observes three contractions in 10 minutes with no late decelerations of the fetal heart rate (FHR). Which of the following actions should the nurse take?

A nurse is using vibroacoustic stimulation (VAS) to stimulate fetal movement during a nonstress test (NST). What action should the nurse take when applying VAS?
