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
“I will have sensors placed on my abdomen to monitor the FHR and uterine contractions.” This statement indicates the client understands the test procedure of a CST, which is a test that triggers contractions and registers how the baby’s heart reacts.
The test is done by placing two sensor belts around the abdomen, one to measure the baby’s heartbeat and the other to measure contractions.
The client may receive oxytocin through an IV to induce contractions.
Choice B is wrong because the client does not need to fast for 24 hours before the test.
There is no evidence that fasting is required for a CST.
Choice C is wrong because the client will not be sedated during the test.
Sedation is not necessary for a CST and may interfere with the results.
Choice D is wrong because the client does not need to drink plenty of fluids before the test.
There is no evidence that drinking fluids is required for a CST.
Correct Answer is B
Explanation
This is because cramping and vaginal bleeding after an amniocentesis may indicate a possible miscarriage or placental abruption, which can compromise fetal oxygenation and perfusion.
Monitoring fetal heart rate can help detect signs of fetal distress and guide further interventions.
Choice A is wrong because administering Rho(D) immune globulin is indicated for Rh-negative mothers who undergo amniocentesis to prevent isoimmunization, but it is not a priority action in this scenario.
Choice C is wrong because assessing maternal vital signs is important to monitor for signs of infection, hemorrhage, or shock, but it is not as urgent as monitoring fetal well-being.
Choice D is wrong because obtaining an order for an ultrasound exam can help confirm the diagnosis and evaluate the placenta and amniotic fluid, but it is not the first action to take in this situation.
