Biophysical Profile (BPP)

  • BPP is a prenatal screening test that combines an NST with an ultrasound to assess five fetal biophysical variables: FHR, fetal breathing movements, fetal body movements, fetal tone, and amniotic fluid volume

    •            

    • BPP can evaluate fetal well-being and identify fetal hypoxia or distress
    • BPP is usually performed after 28 weeks of gestation or earlier if there are risk factors such as diabetes mellitus, hypertension, IUGR, .
    • BPP involves performing an NST and an ultrasound for 30 minutes
    • BPP assigns a score of 0 or 2 to each of the five variables based on predefined criteria
    • A total BPP score of 8 to 10 is normal and indicates a low risk of fetal asphyxia
    • A total BPP score of 6 is equivocal and may indicate chronic fetal asphyxia
    • A total BPP score of 4 or less is abnormal and indicates acute fetal asphyxia
    • A low BPP score requires further evaluation such as a CST or delivery depending on the gestational age and fetal condition

    • BPP has no risks or complications for the pregnant person or the fetus

Questions on Biophysical Profile (BPP)

Correct Answer is A

Explanation

Amniocentesis is wrong because it is a procedure that involves inserting a needle into the uterus to collect a sample of amniotic fluid for testing. It does not assess fetal well-being directly, but rather tests for genetic or chromosomal abnormalities, infections, or lung maturity.

Correct Answer is D

Explanation

A biophysical profile (BPP) is typically performed after 28 weeks of gestation to evaluate the fetal well-being. A BPP measures five parameters: fetal heart rate, fetal breathing movements, fetal body movements, fetal tone and amniotic fluid volume. Each parameter is scored as 0 (abnormal) or 2 (normal), and the total score ranges from 0 to.

A BPP score of 10 or less is considered normal and does not indicate acute fetal asphyxia.
