A nurse is preparing a client for a biophysical profile (BPP).
The nurse should instruct the client that the test involves which of the following procedures?
An ultrasound and a nonstress test.
An ultrasound and a contraction stress test.
A Doppler ultrasound and a nonstress test.
A Doppler ultrasound and a contraction stress test.
The Correct Answer is A
The test involves an ultrasound and a nonstress test.
A biophysical profile (BPP) is a way to check on the overall fetal health by observing the fetus’s heart rate, breathing, movement, muscle tone, and the amount of amniotic fluid surrounding the fetus in the uterus.
It is typically performed after 28 weeks of pregnancy, especially for high-risk pregnancies or if there is a chance of complications.
Choice B is wrong because a contraction stress test is not part of a BPP.
A contraction stress test measures how the fetus’s heart rate changes during contractions induced by oxytocin or nipple stimulation.
It is a different test from a nonstress test, which measures the fetus’s heart rate while moving and at rest without any stimulation.
Choice C is wrong because a Doppler ultrasound is not part of a BPP.
A Doppler ultrasound uses sound waves to measure the blood flow in the umbilical cord and other blood vessels.
It is a different type of ultrasound from the one used in a BPP, which uses sound waves to create images of the fetus and the amniotic fluid.
Choice D is wrong because it combines two incorrect components from choices B and C. A BPP does not involve a Doppler ultrasound or a contraction stress test.

Correct Answer is A
Explanation
An NST is a test that measures the fetal heart rate in response to fetal movement.
It is a non-invasive and simple way to assess fetal well-being.
An NST may be recommended to further evaluate fetal well-being if the CST result is equivocal, meaning that occasional but not persistent late decelerations are present.
Choice B. Amniocentesis is wrong because it is an invasive procedure that involves inserting a needle into the uterus to collect amniotic fluid for genetic testing or fetal lung maturity.
It is not used to evaluate fetal well-being in response to contractions.
Choice C. Magnetic resonance imaging (MRI) is wrong because it is an imaging technique that uses magnetic fields to create detailed pictures of the fetus and the placenta.
It is not used to evaluate fetal well-being in response to contractions.
Choice D. Chorionic villus sampling (CVS) is wrong because it is an invasive procedure that involves inserting a catheter or a needle into the placenta to collect chorionic villi for genetic testing.
It is not used to evaluate fetal well-being in response to contractions.
Normal ranges for CST are negative (normal) or positive (abnormal).
Equivocal and unsatisfactory are special categories of test outcomes that require further testing.
Normal ranges for NST are reactive (reassuring) ornon-reactive (non-reassuring).
Correct Answer is D
Explanation
The correct answer is choice D. The client has a history of placenta previa.
Placenta previa is a condition where the placenta covers all or part of the cervix, blocking the baby’s exit from the uterus.
This can cause severe bleeding during pregnancy and delivery and increase the risk of complications for both the mother and the baby.
Therefore, the nurse should report this condition to the provider before performing an amniocentesis.
Choice A is wrong because having Rh-negative blood type is not a contraindication for amniocentesis.
However, the client may need an injection of Rh immunoglobulin after the procedure to prevent Rh sensitization.
Choice B is wrong because having a history of preterm labor is not a contraindication for amniocentesis.
However, the client may need to be monitored closely for signs of preterm labor after the procedure.
Choice C is wrong because having a history of gestational diabetes is not a contraindication for amniocentesis.
However, the client may need to have their blood glucose levels checked before and after the procedure.
Amniocentesis is a diagnostic procedure that involves removing and testing a small sample of amniotic fluid from the uterus for genetic or chromosomal conditions, such as Down syndrome, Edwards syndrome or Patau syndrome.
It can also be used to diagnose fetal infections, treat excess amniotic fluid, or test fetal lung maturity
