A nurse is performing a nonstress test (NST) for a client who is at 28 weeks of gestation and has intrauterine growth restriction (IUGR).
The nurse observes that the fetal heart rate (FHR) does not accelerate with fetal movement after 20 minutes of monitoring.
Which of the following tests should the nurse anticipate to be ordered next for this client? (Select all that apply.)
Biophysical profile (BPP)
Contraction stress test (CST)
Umbilical artery Doppler velocimetry
Amniocentesis
Fetal kick count
Correct Answer : A,C
A biophysical profile (BPP) is a test that combines a nonstress test with an ultrasound to assess fetal well-being. A umbilical artery Doppler velocimetry is a test that measures the blood flow in the umbilical cord to detect fetal growth restriction. Both of these tests are indicated for a client who has a nonreactive nonstress test (NST), which means that the fetal heart rate does not accelerate with fetal movement after 20 minutes of monitoring.
Choice B is wrong because a contraction stress test (CST) is a test that stimulates uterine contractions to evaluate how the fetal heart rate responds to stress. It is not recommended for clients who have intrauterine growth restriction (IUGR) because it can compromise fetal oxygenation.
Choice D is wrong because an amniocentesis is a test that obtains amniotic fluid for genetic testing, fetal lung maturity, or infection. It is not used to assess fetal well-being or growth.
Choice E is wrong because a fetal kick count is a method of monitoring fetal movement at home by counting how many times the fetus kicks in a certain period of time. It is not a test that can be ordered by a health care provider.

Correct Answer is D
Explanation
“This test will evaluate your baby’s well-being by monitoring his or her movements.”
A nonstress test (NST) is a simple, noninvasive way of checking on your baby’s health.The test records your baby’s movement, heartbeat, and reaction to movement.It is done after 26 to 28 weeks of pregnancyto check the health and oxygen supply of the fetus.It is safe, painless, and non-invasive, and can be performed in a doctor’s office or a hospital.It usually takes 40 to 60 minutes.
Choice A is wrong because this test will not measure the amount of amniotic fluid around your baby.That is done by another test called an amniotic fluid index (AFI).
Choice B is wrong because this test will not check if your baby has any chromosomal abnormalities.That is done by other tests such as amniocentesis or chorionic villus sampling (CVS).
Choice C is wrong because this test will not assess how your baby’s heart rate responds to contractions.That is done by another test called a contraction stress test (CST).
Correct Answer is C
Explanation
Explain the purpose, procedure, and possible outcomes of the test to the client.This is because the nurse should always obtain informed consent from the client before performing any procedure, and provide education and reassurance about the test.
Choice A is wrong because applying conduction gel to the client’s abdomen is not the first action the nurse should take.The nurse should first explain the test and obtain consent from the client before applying any equipment.
Choice B is wrong because instructing the client to press a button when she feels fetal movement is part of the nonstress test procedure, but not the first action.The nurse should first educate the client about the test and its purpose.
Choice D is wrong because activating a vibroacoustic stimulation device to wake up the fetus is not necessary for a nonstress test.This device may be used if the fetal heart rate is nonreactive, but only after explaining the test and obtaining consent from the client.
