Biophysical Profile (BPP)
Total Questions : 3
Showing 3 questions, Sign in for moreA nurse is explaining when a biophysical profile (BPP) is usually performed.
At what gestational age is a BPP typically performed?
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.
Choice A is wrong because a BPP is not usually performed at 12-14 weeks of gestation.This is too early to assess the fetal biophysical parameters reliably.
Choice B is wrong because a BPP is not usually performed at 20-22 weeks of gestation.This is also too early to assess the fetal biophysical parameters reliably.
Choice C is wrong because a BPP is not usually performed at 24-26 weeks of gestation.This is still too early to assess the fetal biophysical parameters reliably.
A nurse is caring for a client who has diabetes mellitus and is at 36 weeks of gestation.
The nurse should expect the provider to order which of the following tests to assess fetal well-being?
Explanation
A BPP is a test that combines an ultrasound and a nonstress test (NST) to assess fetal well-being.It measures fetal heart rate, breathing, movement, muscle tone, and amniotic fluid level.A BPP is typically performed after 28 weeks of pregnancy, especially if there are any risk factors or complications.
Choice B.Nonstress test (NST) is wrong because it only measures fetal heart rate in response to movement or contractions.
It does not assess other aspects of fetal well-being such as breathing, movement, muscle tone, and amniotic fluid level.
Choice C. Contraction stress test (CST) is wrong because it measures fetal heart rate in response to induced contractions of the uterus.
It does not assess other aspects of fetal well-being such as breathing, movement, muscle tone, and amniotic fluid level.
Choice D. 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.
A nurse is reviewing the results of a biophysical profile (BPP) for a client who is at 38 weeks of gestation.
The nurse should recognize that a total BPP score of which of the following indicates acute fetal asphyxia?
Explanation
A biophysical profile (BPP) score of 4 or less indicates acute fetal asphyxia.A BPP score is calculated by adding the scores of five parameters: fetal breathing movements, fetal body movements, fetal tone, amniotic fluid volume and nonstress test.
Each parameter is scored as either 0 (abnormal) or 2 (normal), except for the nonstress test which is scored as either 0 (nonreactive) or 1 (reactive).A total score of 8 or more is considered normal, while a score of 6 or less is considered abnormal and requires further evaluation or delivery.
Choice B is wrong because a BPP score of 6 or less, not 6 or more, indicates acute fetal asphyxia.
Choice C is wrong because a BPP score of 8 or less is considered borderline and may require repeat testing or delivery depending on the clinical situation.
It does not necessarily indicate acute fetal asphyxia.
Choice D is wrong because a BPP score of 10 or less is considered normal and does not indicate acute fetal asphyxia.
