Non-Stress Test (NST)
Non-Stress Test (NST) ( 5 Questions)
During a Non-Stress Test (NST), the fetal heart rate (FHR) increases by at least 15 beats per minute for at least 15 seconds twice or more in a 20-minute period.
How should the nurse interpret this finding?
A reactive NST indicates adequate fetal oxygenation and normal fetal neurological function. This means that the fetal heart rate increases by at least 15 beats per minute for at least 15 seconds twice or more in a 20-minute period. This is a sign of a healthy and active fetus.
A nonreactive NST does not necessarily mean that there is a problem with the fetus. It could mean that the fetus is asleep, not moving enough, or has a medication effect. A nonreactive NST requires further evaluation such as a biophysical profile (BPP) or a contraction stress test (CST) to confirm fetal well-being.
NST has some risks and complications for the pregnant person or the fetus. For example, NST may cause anxiety, false-positive results, or unnecessary interventions if the test is not interpreted correctly.
NST is not a prenatal screening test that measures the FHR in response to fetal movements. NST is a prenatal diagnostic test that measures the FHR in response to uterine contractions.

Choice B is wrong because a nonreactive NST does not necessarily mean that there is a problem with the fetus.

Choice C is wrong because NST has some risks and complications for the pregnant person or the fetus. For example, NST may cause anxiety, false-positive results, or unnecessary interventions if the test is not interpreted correctly.
Choice D is wrong because NST is not a prenatal screening test that measures the FHR in response to fetal movements. NST is a prenatal diagnostic test that measures the FHR in response to uterine contractions.
Fetal movements are recorded by the pregnant person using a button during the test.
