A client with a history of diabetes mellitus (T1 D) is 32 weeks pregnant.The client returns to the clinic for a scheduled ultrasound and non-stress test.
What should the nurse expect the non-stress test to determine?
Mother’s ability to tolerate the discomfort of labor.
Fetal lie.
Well-being of the fetus.
Maternal readiness for labor.
The Correct Answer is C
A nonstress test (NST) is a test in pregnancy that measures fetal heart rate and reaction to movement. Your pregnancy care provider performs a nonstress test to make sure the fetus is healthy and getting enough oxygen. It’s safe and painless, and gets its name because it puts no stress (nonstress) on you or the fetus.
Choice A is wrong because a nonstress test does not measure the mother’s ability to tolerate the discomfort of labor. A stress test is a different procedure that involves stimulating contractions and monitoring how the fetus responds.
Choice B is wrong because a nonstress test does not measure fetal lie, which is the position of the fetus in the uterus.
Fetal lie is usually determined by ultrasound or physical examination.
Choice D is wrong because a nonstress test does not measure maternal readiness for labor. A nonstress test typically happens after 28 weeks of pregnancy, when fetal heart rate starts reacting to movements.
Maternal readiness for labor is assessed by other factors, such as cervical dilation and effacement.

Correct Answer is B
Explanation
he correct answer is choice B. Sufficient perfusion and circulation of the fetus.This is because the fetal heart rate is within the normal range of 110 to 160 beats per minute, and there is moderate beat-to-beat variability, which indicates a healthy nervous system.
Choice A is wrong because insufficient perfusion of the placenta would cause fetal distress and abnormal fetal heart rate patterns, such as late decelerations or minimal variability.
Choice C is wrong because maternal hypoxia would not directly affect the fetal heart rate, unless it leads to placental insufficiency or uterine hyperstimulation.
Choice D is wrong because fetal hypoxia would cause signs of fetal distress, such as tachycardia, bradycardia, or absent variability.
