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.)
A.
Fetal breathing movement
B.
Fetal tone
C.
Reactive fetal heart rate
D.
Amniotic fluid volume
E.
Fetal position
The correct answer and Explanation is :
The correct components of the Biophysical Profile (BPP) score are:
- A. Fetal breathing movement
- B. Fetal tone
- C. Reactive fetal heart rate
- D. Amniotic fluid volume
Explanation:
The Biophysical Profile (BPP) is a prenatal test used to assess the health and well-being of a fetus, typically in the third trimester of pregnancy. It combines an ultrasound evaluation with a nonstress test (NST) to evaluate five specific criteria, each worth 2 points, for a total of 10 points. These criteria are:
- Fetal Breathing Movements (FBM): This assesses the presence of fetal breathing movements (the movement of the diaphragm). At least one episode of rhythmic breathing lasting at least 30 seconds within 30 minutes is considered normal.
- Fetal Tone: This evaluates the fetus’s muscle tone by looking for movements like flexion and extension of the limbs. At least one episode of active extension with return to flexion of a limb or trunk indicates normal fetal tone.
- Fetal Movement: The ultrasound assesses fetal body movement. At least three movements of the body or limbs within 30 minutes are considered normal.
- Amniotic Fluid Volume (AFV): This assesses the amount of amniotic fluid. An adequate volume indicates the fetus is producing urine and swallowing properly. A single fluid pocket measuring at least 2 cm in two planes is considered normal.
- Reactive Fetal Heart Rate (FHR) (measured via nonstress test): This evaluates the fetal heart rate response to fetal movements. Two or more accelerations in 20 minutes is a sign of a healthy fetal autonomic nervous system.
Each component is scored either 0 (abnormal) or 2 (normal). A BPP score of 6 is borderline, potentially indicating fetal compromise, depending on other clinical findings. Immediate follow-up or delivery may be considered, particularly at 40 weeks of gestation.
Option E (Fetal Position) is not included in the BPP score.
