Introduction ( 5 Questions)
A nurse is evaluating the results of a fetal non-stress test (NST) for a client who has diabetes mellitus and is at 36 weeks of gestation.
The nurse notes that the fetal heart rate (FHR) baseline is 150 bpm, with occasional increases of 20 bpm that last for 20 seconds.
There are no decelerations of the FHR.
How should the nurse document this finding?
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.
A nonreactive NST means that the FHR does not show the expected accelerations, which could indicate fetal hypoxia or other problems.
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.
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.
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.
