A nurse is teaching a pregnant client about the advantages and limitations of nonstress test (NST).
Which statement by the client indicates a need for further teaching?
“The test is safe and simple for me and my baby.”
“The test is inexpensive and widely available.”
“The test can tell me if my baby has any birth defects.”
“The test can be repeated as often as needed without any harm.”
The Correct Answer is C
The test can tell me if my baby has any birth defects.
This statement indicates a need for further teaching because a nonstress test (NST) does not detect birth defects. An NST is a prenatal test that measures the fetal heart rate and movement to assess the health and oxygen supply of the fetus. It is usually done for high-risk pregnancies or when there are concerns about fetal well-being.
Choice A is correct because an NST is safe and simple for both the pregnant person and the fetus. It is a noninvasive test that does not pose any physical risks or stress.
Choice B is correct because an NST is inexpensive and widely available. It is a common test that can be done in most healthcare settings with minimal equipment.
Choice D is correct because an NST can be repeated as often as needed without any harm. It can be done at certain intervals or during delivery depending on the situation.

Correct Answer is ["A","E"]
Explanation
Maternal medications and technical errors can contribute to a nonreactive nonstress test (NST), which means that the fetal heart rate (FHR) does not increase with fetal movement.Some medications, such as narcotics, antihypertensives, and magnesium sulfate, can affect the FHR and its variability.Technical errors, such as poor transducer placement or loose belts, can also interfere with the accuracy of the NST.
Choice B is wrong because a fetal sleep cycle usually lasts 20 to 40 minutes, and the NST can be extended or repeated if the FHR is not reactive within 20 minutes.
Choice C is wrong because maternal obesity does not affect the FHR or its reactivity, but it may make it harder to obtain a clear signal from the transducer.
Choice D is wrong because fetal breathing movements are a sign of fetal well-being and do not cause a nonreactive NST.
A normal NST will show a baseline FHR between 110 and 160 beats per minute with moderate variability (5 to 25 interbeat variability) and two qualifying accelerations in 20 minutes with no decelerations.An acceleration is defined as an increase in the FHR of at least 15 beats per minute for at least 15 seconds.
Correct Answer is A
Explanation
To assess fetal oxygenation.The primary purpose of a nonstress test (NST) is to check the baby’s heart rate before birth and see how it responds to movement and contractions.The test can help determine if the baby is healthy and has enough oxygen.The test is usually done in the third trimester of pregnancy, especially if there are any risk factors or concerns.The test is simple and noninvasive.
Choice B is wrong because measuring fetal growth is not the main goal of an NST.
Fetal growth can be assessed by other methods, such as ultrasound or fundal height measurement.
Choice C is wrong because evaluating fetal anomalies is not the main goal of an NST.
Fetal anomalies can be detected by other tests, such as amniocentesis or chorionic villus sampling.
Choice D is wrong because monitoring fetal activity is not the main goal of an NST.
Fetal activity can be monitored by other ways, such as counting kicks or using a handheld Doppler device.
