A nurse is preparing a client for a fetal non-stress test (NST).
Which of the following instructions should the nurse give to the client?
“You will need to fast for 8 hours before the test.”
“You will need to drink plenty of fluids before the test.”
“You will need to lie on your back during the test.”
“You will need to press a button when you feel the baby move.”
The Correct Answer is D
“You will need to press a button when you feel the baby move.” This is because a non-stress test (NST) is a pregnancy screening that measures fetal heart rate and reaction to movement. The test is performed to make sure the fetus is healthy and getting enough oxygen. By pressing a button when the baby moves, the patient can help the provider record the changes in the fetal heart rate.
Choice A is wrong because the patient does not need to fast for 8 hours before the test. There is no dietary restriction for an NST.
Choice B is wrong because the patient does not need to drink plenty of fluids before the test. However, drinking some fluids may help stimulate fetal movement.
Choice C is wrong because the patient does not need to lie on their back during the test. In fact, lying on the back can compress the blood vessels and reduce blood flow to the fetus. The patient can lie on their side or recline on a chair or exam table.

Correct Answer is A
Explanation
Reactive NST.This means that the fetal heart rate (FHR) increases by at least 15 bpm for at least 15 seconds twice in a 20-minute period.This indicates that the fetus is well-oxygenated and not in distress.
Choice B is wrong because a nonreactive NST means that the FHR does not show the expected accelerations, which could indicate fetal hypoxia or other problems.
Choice C is wrong because a positive NST is another term for a contraction stress test (CST), which measures the FHR response to uterine contractions.A positive CST means that the FHR shows late decelerations, which indicate uteroplacental insufficiency.
Choice D is wrong because a negative NST is also another term for a CST, but it means that the FHR does not show late decelerations, which indicate normal fetal oxygenation.
